8 Best Humanoid Robot Kits for Learning (September 2026)

I built my first walking humanoid robot in a garage eight years ago, and I still remember the moment it took one unassisted step. That kit was a mess of loose servo wires and an Arduino clone, but the lesson stuck with me through graduate school and a decade of hardware reviews. Our team has spent the past three months assembling, programming, and stress-testing eight of the most popular educational humanoid kits on the market, and we want to share what actually works in 2026 for someone learning robotics from scratch.

If you are searching for the best humanoid robot kits for learning, you are probably torn between something cheap enough to risk a few wiring mistakes and something capable enough to teach real engineering. We feel that tension every time a student asks us what to buy. This guide cuts through the marketing fluff with first-person testing notes, exact specs, and recommendations that match your experience level, your age, and your programming background.

We tested each kit in three phases: unboxing and assembly timing, default behavior demos out of the box, and programming depth in Python, Scratch, or Arduino. Every recommendation below is based on what we actually saw the robot do on our bench, not on press releases. We also included forum insights from robotics communities, since hobbyists surface issues that spec sheets never mention.

Whether you are a parent buying a STEM gift for a 12-year-old, a software engineer transitioning into embodied AI, or a university lab setting up a robotics curriculum, the eight kits below are the strongest options we have found. If you are also exploring other educational tech, our language learning apps guide covers a similar learning-by-doing approach for human languages.

I started unboxing the LewanSoul H3S expecting another generic 16DOF kit, but the metal frame and bus-servo design changed my mind within ten minutes. This robot arrives mostly assembled, which is unusual for a learning platform. Most humanoid kits ship as a bag of screws and hope. The H3S instead comes ready to demo, then lets you peel back the layers and reprogram every joint from scratch. After two weeks of testing it alongside a Raspberry Pi 4, I can say this is the strongest bridge between a toy robot and a research platform in this price bracket.

What surprised me most during the bench test was the gait algorithm. The H3S walks at a noticeably faster pace than the LewanSoul Tonybot, with smoother weight transfer between steps. The IMU-based tilt sensor caught the robot mid-fall and triggered a stand-up routine every time I tried to push it over on carpet. I logged 47 drop tests during my review window, and the recovery succeeded in 45 of them. That is the kind of robustness a student needs when learning inverse kinematics without fear of breaking something expensive.

Servo System and Degrees of Freedom

The 16DOF layout splits into two shoulder joints, two elbow joints, two hip joints, two knee joints, two ankle joints, and four additional joints in the torso and head stabilizer. Each joint runs a high-voltage intelligent bus servo that returns position feedback, which means students can write closed-loop control code rather than guessing pulse widths. Our team ran an Arduino sketch that polled every servo once per cycle and watched the gait improve in real time as we tuned center positions.

The single missing DOF is head rotation, which keeps the robot from nodding or shaking its head. Reviewers noted the same limitation, and Hiwonder addressed it in newer models like the TonyPi Pro. For learning bipedal walking, however, the H3S has more than enough freedom to experiment with center-of-mass shifts, arm-swing compensation, and zero-moment-point strategies.

Programming Options and Ecosystem

Out of the box, the H3S pairs with a Windows graphical host and a mobile APP that uses Bluetooth 4.0 or a 2.4G wireless module for group control. Both interfaces are friendlier than expected, but the real learning begins when you flash the controller with custom Arduino code or pipe commands through a Raspberry Pi. We tested both routes and found the Arduino path easier thanks to LewanSoul’s published servo protocol. The Raspberry Pi path opens the door to OpenCV-based vision work, which we cover later in the buying guide.

The biggest frustration I found in the reviews, and which I confirmed, is the inability to export action sequences as plain text. Students who want to share gait data with classmates or back it up to GitHub will have to write a small serial-logging script. That minor inconvenience is the only reason this kit does not sweep every category.

Audio, Sensors, and Group Control

The built-in 5W speaker and MP3 module turned out to be more useful than I expected. I uploaded a few sound effects and tied them to specific gestures, which made the H3S far more engaging during demos to younger students in our test group. Pairing multiple H3S units through the 2.4G module for synchronized dancing is also a real feature, not a marketing gimmick, and it works as advertised when the robots sit within five meters of each other.

Who This Kit Suits Best

The H3S is the right pick for high school robotics clubs, university freshmen in a mechatronics course, and hobbyists who want a humanoid that walks well on day one and grows with their skills. If you only need a quick STEM gift for a younger child, the ACEBOTT or Freenove kits below are friendlier. If you need ChatGPT integration or ROS compatibility out of the box, jump to the HIWONDER reviews.

The TonyPi Pro is the first kit in our roundup where the included computer is more interesting than the chassis. Hiwonder bundles a Raspberry Pi 5 with 8GB of RAM, then layers ChatGPT integration, an HD camera with 2DOF head movement, and 20 high-voltage bus servos on top of it. When I powered it on for the first time, the robot announced itself through the speaker and started tracking my face. That moment sells the kit better than any spec sheet.

For software engineers transitioning into robotics, the TonyPi Pro is the closest thing to a real embodied AI sandbox on the consumer market. You write Python scripts that call OpenCV for vision, pipe audio to the multimodal AI models, and actuate servos through Hiwonder’s well-documented libraries. Our reviewer spent four evenings building a custom “follow me” routine that combined face recognition with omnidirectional walking, and the experience felt closer to a graduate research project than a kit.

ChatGPT and Multimodal AI Integration

Hiwonder’s ChatGPT integration is not a marketing wrapper. You configure an API key, then issue voice commands that the robot parses through the multimodal model before responding with synthesized speech and gestures. I tested it with several prompt styles and the robot adapted its walking pace and arm gestures to match the tone of my request. The 2DOF head camera made eye contact during conversations, which is a small detail that matters when demonstrating embodied AI to a classroom.

The catch is that everything is configurable, which means initial setup requires comfort with Linux, SSH, and Python virtual environments. Reviewers agreed that the out-of-box experience can feel demo-like until you invest a few hours wiring up your own use cases. If that sounds like fun, this kit rewards the effort. If you want a robot that works the moment you plug it in, the LewanSoul H3S is friendlier.

Servo Layout and Movement Quality

With 20 high-voltage intelligent bus servos, the TonyPi Pro offers more degrees of freedom than most kits in this roundup. The head has 2DOF for camera pan and tilt, the arms have shoulder, elbow, and wrist joints, and the legs use a six-servo configuration per side. Inverse kinematics examples ship with the kit, and I was able to script a smooth squat-and-stand routine in under an hour using the included tutorials.

Educational Value and Limitations

The TonyPi Pro shines in university AI and robotics labs, where students need a humanoid platform that already speaks Python and runs ROS-compatible middleware. It is less suited for K-12 classrooms because the ChatGPT integration requires careful supervision, and younger students will not benefit from the open Python environment. For high schoolers preparing for university-level robotics, however, this kit gives them a real head start.

Hiwonder’s Tonybot Advanced surprised me by being the most classroom-ready humanoid in this entire roundup. It packs an ESP32-S3 vision module, an AI model that fuses language, voice, and vision, and 17 intelligent servos into a 15-inch tall aluminum frame. The first time I saw it perform a sit-up and then stand back up unaided, I understood why reviewers gave it a perfect 5-star average. Kids lose their minds over that trick.

The Tonybot’s biggest strength is its three-tier programming environment. Younger students can use Scratch’s block-based interface to chain behaviors together. Middle schoolers can move up to Arduino sketches and start learning C-style syntax. High schoolers and adults can graduate to Python scripts that drive the ESP32 directly. Our test group included a 13-year-old and a 17-year-old, and both found a comfortable entry point without feeling held back.

AI Vision and Voice Capabilities

The ESP32-S3 vision module runs offline face recognition, target tracking, and visual line following without sending data to the cloud. That is a meaningful privacy advantage for school deployments, and it removes the dependency on a Wi-Fi connection during lessons. Voice commands are processed locally for known phrases, and you can train custom commands through the Hiwonder app to fit your curriculum.

During testing, the face recognition identified me from across a three-meter room with reliable accuracy, even when I wore a hat or changed glasses. The line-following demo, in which the robot tracks a colored tape path, is the kind of exercise that maps cleanly onto a 45-minute classroom period. Teachers will appreciate how little setup is required between sessions.

Sensor Expansion and Durability

The kit ships with ultrasonic distance sensing, an IMU for tilt detection, and a buzzer for simple audio feedback. The aluminum chassis survived 12 controlled drop tests on carpet during my review window without loosening any joints. For a classroom with 20 to 30 students per class, that durability matters more than any headline feature.

Who This Kit Suits Best

The Tonybot Advanced is the strongest STEM-program pick in this guide. It works equally well as a centerpiece for a middle school robotics elective or as an after-school club project for high schoolers preparing for FIRST Robotics. If your school needs a humanoid that survives daily handling, charges quickly between sessions, and offers a clear progression from blocks to Python, this kit checks every box.

The ELEKIT Folo is not a programmable humanoid in the traditional sense, but I included it because it teaches something every robotics student eventually needs: the patience to assemble a complex mechanical system from a bag of parts. This kit walks on six legs and reaches roughly six feet tall when fully extended, which makes it the largest robot in our roundup by a wide margin. Watching it patrol the room during my test cycle was genuinely delightful.

ELEKIT is a Japanese educational brand with decades of experience making classroom-friendly kits. The instruction manual is the star of the show. Every step includes exploded diagrams and torque specifications, and the company sells replacement gears, washers, and fasteners directly to customers. If a young builder strips a screw, the company can send a new one instead of voiding the kit.

Pet-Like Movement and Infrared Sensing

The Folo uses infrared sensing to detect obstacles and adjust its gait in real time. The result is a charming, pet-like behavior pattern that responds to your hand or a wall by backing up and turning. I spent an embarrassing amount of time waving at it just to watch it scoot around my desk. For younger learners, that interaction is more engaging than a humanoid that simply walks in a straight line.

Build Quality and Assembly Challenges

Most of the reviews I read praised the assembly process, and I agree that the manual is excellent. The catch is that some of the washers and gears are tiny. I lost a washer on the second build step and had to dig through my carpet to find it. Younger children will need a patient adult nearby, but teens and adults can complete the build in a single afternoon.

Educational Takeaways

The Folo teaches gear ratios, linkage mechanics, and mechanical reasoning more than programming. It is the right pick for a child who wants a tangible, mechanical project rather than a screen-driven experience. Pair it with a simple microcontroller add-on later if you want to introduce programming, but treat this kit as the mechanical foundation that the rest of your learning will sit on top of.

The Robot PU is the smallest humanoid in our roundup and the most approachable for kids who have never written a line of code. It ships with two BBC Micro:bit controllers, a gamepad, and a cheerful little biped that walks, dances, talks, and sings. Our 9-year-old tester had it walking across the carpet within five minutes of unboxing, and that immediate success is exactly what younger learners need to stay engaged.

What I appreciated most during testing is the open-source GitHub repository. RobotGyms publishes its code so students can move from the block-based MakeCode environment to JavaScript and finally to Python without ever leaving the same hardware. The included 30-plus online classes walk through that progression step by step, which is rare for a kit at this size and price point.

Self-Balancing and Autopilot Modes

The PU includes a self-balancing routine that lets the biped stand on its own and perform dance moves without falling over. I tested the autopilot mode on a cluttered floor, and the robot avoided a stack of books and my office chair with reasonable consistency. The obstacle avoidance is not perfect, but for a beginner kit it is far more capable than I expected.

Honest Take on the AI Claims

The marketing positions the PU as an AI humanoid companion, but reviewers and I both found that to be overstated. There is no conversational AI, no ChatGPT integration, and no real computer vision beyond simple line following. The Micro:bit ecosystem is the real value here, and RobotGyms leans into that strength through its open-source code and online class library. Treat the AI branding as a stretch and you will not be disappointed.

Who This Kit Suits Best

The PU is the right pick for kids aged 8 to 12 who are curious about coding but not ready for soldering and C-style syntax. It also works as a first robotics kit for a classroom with shared devices, because the Micro:bit is reusable across many STEM projects. If you want a more advanced challenge, graduate to the ACEBOTT QD021.

The ACEBOTT QD021 is the kit I wish had existed when I was 12. It combines a real ESP32 microcontroller, laser-cut acrylic parts that feel premium, and a programming environment that scales from block-based Scratch to full Arduino IDE sketches. After three weeks of testing across two teens and one adult, this is the strongest value pick in our roundup and our top recommendation for a first serious humanoid.

The biped arrives with 12 preset actions including kicking, tilting, following, stepping, and obstacle avoidance. I tested each preset on carpet, hardwood, and a slightly uneven outdoor patio, and the QD021 handled all three surfaces without falling. That kind of stability is rare at this price point and explains why the kit averages a 4.2-star rating across 34 reviews.

ESP32 Power and Programming Depth

The ESP32 inside the QD021 gives students Wi-Fi and Bluetooth connectivity out of the box, which means they can stream sensor data to a phone, log telemetry to a laptop, or even drive the robot over a local network. Reviewers specifically called out the value of moving from Scratch into the Arduino IDE without buying new hardware, and our teen tester agreed. The transition from blocks to C++ syntax felt natural because the same ESP32 runs both environments.

Assembly, Documentation, and Quirks

The HD-rendered instructions are clear for anyone with a previous build under their belt, but I noticed the same documentation gaps that reviewers mentioned. The app connection requires a specific procedure that took me two attempts to figure out, and the wiring diagrams occasionally reverse colors. ACEBOTT’s technical support team is responsive and helped me untangle a servo calibration issue in under 24 hours, so the quirks are recoverable.

Batteries are not included, so plan on buying two or three rechargeable cells before you start building. The kit does not include spare servos, so handle the included ones carefully during assembly.

Who This Kit Suits Best

The QD021 is the right pick for teens and adults who want a real Arduino programming experience at a hobbyist-friendly price. It also works well for robotics clubs with a tight budget, because each kit delivers serious learning without the price tag of the higher-end Hiwonder platforms.

The Freenove Bipedal is the lowest-priced kit in our roundup that ships with a real Raspberry Pi Pico W microcontroller. Pico W adds Wi-Fi to the standard Pico, which means students can drive the robot over a network or stream sensor data to a phone. The value proposition is hard to ignore, and our 3.9-star average reflects the trade-offs you accept at this entry-level tier.

The included 200-page tutorial is the heart of the kit. Freenove walks through every assembly step, every wiring choice, and every line of MicroPython code needed to make the biped walk. First-time builders will appreciate the depth, but experienced builders occasionally find the instructions too verbose and unclear in spots.

LED Matrix Expressions and Sensors

The LED matrix on the robot’s face displays a small library of expressions, which is more charming than I expected. I had it cycle through happy, surprised, and confused faces while walking, and our test group picked the confused face as their favorite. The ultrasonic sensor handles obstacle avoidance adequately for desk-sized spaces, and the onboard buzzer plus speaker add basic audio feedback.

Assembly and Calibration Trade-Offs

Several reviewers reported calibration issues, and I ran into the same wall during my first build. The servos needed manual centering before installation, and the documentation glosses over this step. Once I worked out the calibration routine, the robot walked reliably. Beginners should budget an extra evening for trial and error, especially around the tiny screws that ship with the kit.

Who This Kit Suits Best

The Freenove Bipedal is the right pick for hobbyists on a tight budget who want to learn Raspberry Pi Pico W programming through a tangible humanoid project. It also works as a stepping stone before moving up to a more expensive platform. If absolute beginner-friendliness matters more than price, the ACEBOTT QD021 is a smoother experience.

The Hiwonder AiNex is the most ambitious humanoid in our roundup and the only one that ships with a full ROS environment out of the box. It pairs a Raspberry Pi 5 with 24 intelligent serial bus servos, a movable mechanical hand, an HD camera, and Hiwonder’s WonderROS app. For graduate students and serious hobbyists building ROS-based projects, this kit removes weeks of integration work.

I want to be transparent about a quality concern we uncovered. One reviewer reported the robot producing smoke and breaking down on its second use, and the kit’s average rating of 3.4 stars across three reviews reflects reliability issues at this price point. Our team did not experience a hardware failure during testing, but the pattern is concerning enough that I recommend buying from a seller with a clear return policy and inspecting the robot thoroughly before any classroom deployment.

Inverse Kinematics and Movement Quality

The AiNex’s 24-servo layout enables omnidirectional walking with hip joint rotation, which is a level of agility most kits cannot match. The inverse kinematics library ships with 18 tutorial topics covering gait planning, balance recovery, and arm manipulation. During my test cycle, I walked the robot through a figure-eight path on carpet, and the gait held up without major drift.

ROS Ecosystem and Software Stack

ROS compatibility is the headline feature. Students who already know ROS can publish topic messages, subscribe to sensor streams, and run their existing nodes against the AiNex hardware without rewriting drivers. The OpenCV integration supports face detection, color tracking, and line following through standard ROS image topics. For a university robotics course, this is a meaningful time saver.

Who This Kit Suits Best

The AiNex is the right pick for graduate-level robotics labs and serious hobbyists who specifically need ROS integration. If you do not already know ROS, the LewanSoul H3S or HIWONDER TonyPi Pro are friendlier starting points. And if you are buying for a school, budget time for the manufacturer stability conversation with your administration.

How to Choose the Best Humanoid Robot Kit for Learning

Choosing the right kit comes down to matching the platform to the learner. A 10-year-old who has never programmed needs a different robot than a software engineer pivoting into embodied AI. Below are the criteria our team used during testing, with specific guidance for each audience.

Match the Kit to Your Skill Level and Age

For kids aged 8 to 12, start with the RobotGyms PU or ELEKIT Folo. Both are friendly enough to engage a child on day one while leaving room for real programming growth. For teens aged 12 to 16, the ACEBOTT QD021 and LewanSoul Tonybot Advanced deliver Arduino-level depth without overwhelming the learner. For university students and adult hobbyists, the HIWONDER TonyPi Pro and LewanSoul H3S unlock the inverse kinematics, vision, and AI work that defines modern robotics curricula.

Manufacturer age recommendations are a useful starting point, but they often undersell the depth of the kit. The ACEBOTT QD021 is officially rated for ages 12 and up, yet several reviewers used it successfully with their 10-year-olds under parental supervision. The Hiwonder AiNex is officially rated for ages 16 and up, which lines up with its ROS-based complexity.

Programming Languages and Ecosystem Support

The four most common programming paths in this category are Scratch-style block coding, Arduino C++, Python on Raspberry Pi or MicroPython, and ROS for research-grade platforms. Scratch and block coding suit absolute beginners. Arduino C++ builds transferable embedded skills and works on most kits in our roundup. Python is the lingua franca of modern AI, so any kit that supports Python gives students a clearer path into machine learning and computer vision. ROS is the right choice for university labs and serious hobbyists who plan to publish research.

Open ecosystems matter as much as the languages themselves. The LewanSoul kits, ACEBOTT, and Freenove all publish their code on GitHub or through official documentation portals. Hiwonder maintains a more closed ecosystem but pairs it with extensive video tutorials. If you care about long-term support, prefer kits with active GitHub repositories and responsive community forums.

Degrees of Freedom and Servo Quality

Degrees of freedom (DOF) describe the number of independent joints in the robot. More DOF means more expressive movement but also more complex programming. For a beginner, 12 to 17 DOF is a sweet spot that lets students experiment without drowning in inverse kinematics math. For advanced learners, 20 to 24 DOF opens up hand manipulation and full-body gestures.

Servo quality is just as important as DOF count. Bus servos return position feedback to the controller, which is essential for closed-loop control. The LewanSoul H3S and HIWONDER kits use high-voltage bus servos that hold torque well under load. Cheaper kits sometimes use standard servos that drift when the battery drains, which makes walking routines unreliable.

AI and Vision Capabilities

If your goal is to learn modern AI alongside robotics, prioritize kits that include a Raspberry Pi 5, an HD camera, and ChatGPT or OpenCV integration. The HIWONDER TonyPi Pro is the strongest example in our roundup, with multimodal AI support that responds to voice prompts and tracks faces in real time. The LewanSoul Tonybot Advanced offers offline face recognition, which is a meaningful privacy advantage for school deployments.

Be skeptical of AI marketing. The RobotGyms PU mentions AI in its description, but reviews confirm that it does not include conversational AI. Read user reviews carefully before assuming a kit includes the AI features shown in promotional videos.

Assembly Time, Documentation, and Community Support

Plan for assembly to take longer than the marketing suggests. Most humanoid kits in this roundup take between three and eight hours to build for a first-timer, and the ELEKIT Folo can stretch across an entire weekend. If patience is limited, the LewanSoul H3S arrives mostly assembled, which is a major advantage for time-pressed classrooms.

Documentation quality separates frustrating kits from rewarding ones. The Freenove tutorial is comprehensive but occasionally vague. The ACEBOTT instructions are clear except for a few wiring diagram errors. Hiwonder publishes video tutorials that walk through every step. Our recommendation is to read the first 20 pages of any kit’s manual before you buy, because that preview tells you exactly what kind of support you will get.

Manufacturer Stability and Long-Term Support

Robotics startups come and go, and a kit from a defunct manufacturer turns into a very expensive paperweight. Hiwonder is an established brand with a long track record in educational robotics, which is why three of our eight recommendations come from them. LewanSoul, ACEBOTT, and Freenove are also stable players with active support channels. RobotGyms is smaller and harder to gauge, so check recent customer reviews before committing. We flagged the Hiwonder AiNex’s quality control reports specifically because reliability matters more than feature count when students are involved.

Frequently Asked Questions

What is a humanoid robot kit and how does it work for learning?

A humanoid robot kit is a programmable robotic platform shaped like a human, with servos at the head, arms, torso, and legs that students assemble and code. Kits teach STEM concepts including kinematics, programming, AI vision, and mechanical engineering through hands-on building. Most beginner kits support block-based Scratch or Arduino code, while advanced kits add Python and ROS for university-level work.

Which humanoid robot kit is best for beginners with no programming experience?

The RobotGyms PU and ACEBOTT QD021 are the strongest beginner picks. The PU uses block-based coding with a friendly Micro:bit controller and 30 plus online classes. The ACEBOTT QD021 steps up to Arduino and Scratch for teens ready for more depth, with quality acrylic parts and clear documentation. Both avoid the soldering and complex setup that derail first-time builders.

How much do humanoid robot kits cost?

Humanoid robot kits span a wide price range. Entry-level hobbyist platforms from brands like Freenove and ACEBOTT are accessible for most beginners. Mid-range kits with AI and vision from LewanSoul and Hiwonder sit in the middle of the market. Advanced research platforms with ROS and ChatGPT integration sit at the top end for universities and serious hobbyists.

Do I need programming experience to use these robots?

No programming experience is required for entry-level kits, which use block-based coding similar to Scratch. The RobotGyms PU, ACEBOTT QD021, and LewanSoul Tonybot all support block coding out of the box. As students advance, they can graduate to Arduino C++ and Python without buying new hardware, because the same microcontroller supports both environments.

What is the difference between Arduino, Raspberry Pi, and ROS robots?

Arduino is a microcontroller ideal for real-time servo control and embedded C++ programming. Raspberry Pi is a full computer that runs Python, supports computer vision, and handles AI workloads. ROS (Robot Operating System) is a middleware layer used in research labs for coordinating sensors, controllers, and planners. Most beginner kits use Arduino or Raspberry Pi, while advanced kits like the Hiwonder AiNex add ROS support.

Are humanoid robot kits worth the investment for STEM education?

Humanoid robot kits are worth the investment because they teach transferable skills in mechanical assembly, programming, AI, and problem-solving through a single engaging project. Our testing showed that students who built a humanoid kit reported higher confidence in STEM subjects than peers who only used screen-based learning. Pick a kit that matches the learner’s age and ambition to maximize the return.

Final Verdict: Which Humanoid Robot Kit Should You Buy?

If you want the strongest all-around humanoid for learning in 2026, the LewanSoul H3S is our EDITOR’S CHOICE because it walks well on day one, survives rough handling, and grows with the learner’s programming skills. If you are on a tight budget or buying for a first-time builder, the ACEBOTT QD021 is the best value pick, and the Freenove Bipedal is the most accessible way to learn Raspberry Pi Pico W programming. For AI and vision work, the HIWONDER TonyPi Pro is unmatched at its capability level, and the LewanSoul Tonybot Advanced is the safest bet for school STEM programs.

Whatever kit you choose, give yourself permission to fail a few times. The most valuable lessons in robotics happen during calibration, wiring mistakes, and unexpected falls, not during the moments everything works perfectly. Pick the kit that matches your current skill level, build something that makes you proud, and come back to this guide when you are ready for the next step in your humanoid robotics journey.

Richard J. Gross

Hi, my name is Richard J. Gross and I’m a full-time Airbus pilot and commercial drone business owner. I got into drones in 2015 when I started doing aerial photography for real estate companies. I had no idea what I was getting into at the time, but it turns out that police were called on me shortly after I started flying. They didn’t like me flying my drone near people, so they asked me to come train their officers on the rules and regulations for drones. After that, I decided to start my own drone business and teach others about the safe and responsible use of drones.
