Two stepper motors drive the wheels, controlled by a DRV8825 motor driver, while an MPU-9250 accelerometer and gyroscope unit measures the angle and acceleration of the system.
Self-balancers are a milestone in your robot building life. They stand on two-wheels, using a PID control loop to actuate the two motors using data from some type of Inertial Measurement Unit (IMU).
One of the challenges in building a balancing robot is tuning the control algorithm. The Proportional-Integral-Derivative (PID) controller is commonly used for this purpose.
An innovator has built a self-balancing one-wheeled robot. Developed using 3D-printed components, the latest innovation can stand still.
