The Balboa 32U4 popping itself up and driving in a figure-eight pattern while balancing and playing circus music with its buzzer.
The Balboa 32U4 is a small, user-programmable balancing robot based on the Arduino-compatible ATmega32U4 AVR microcontroller and featuring two H-bridge motor drivers, quadrature encoders for closed-loop motor control, a full inertial measurement unit (3-axis accelerometer, gyro, and magnetometer) for estimating orientation and balancing, and an optional interface for connecting a Raspberry Pi to make a Raspberry Pi-controlled balancing robot.
