About this item
- A two-wheeled inverted-pendulum robot: an IMU senses the tilt, and the ESP32 drives two steppers hundreds of times a second to keep it upright.
- Once it balances, steer it from your phone over Wi-Fi, and tune the controller live from a web page served by the robot itself.
- Steppers make this kit forgiving: no encoder calibration or motor matching, and precise wheel speed control out of the box.
- It's a satisfying first robotics project and a good platform for experiments in PID, LQR and sensor fusion.
- Included: ESP32-C3 controller, MPU-6050 IMU, two NEMA 17 steppers with silent drivers, a 3S LiPo battery with XT60 connector, a 5 V regulator, the printed chassis and wheels, wiring harness, screws, build guide and firmware.
