The device uses an Arduino Pro and an MPU-6050 accelerometer and gyroscope. The original design uses machined aluminum, but 3D printing should work, too.

The Arduino Pro Mini is connected to the MPU-6050 sensor and the stepper motors. The sensor data is processed by the Arduino, which then sends commands to the stepper motors to adjust the robot ...
