16-299: Elegoo balancing robot lab info. (2025 version)


The lab will involve working with this robot: ELEGOO Tumbller Self-Balancing Robot Car Kit Compatible with Arduino IDE, which is a Two Wheeled Inverted Pendulum (TWIP), like a Segway.


The original V1.1 Tumbller seems to be always sold out on the Elegoo site but is available on amazon.com. This year we are modifying the controller board and using a new processor, the Nano RP2040 Connect, to get the full signals from the encoders to directly measure what direction the wheel is turning, get better wheel velocity measurements, sample the IMU faster, and generally sample faster and have a lot more compute power. See Info on robot hardware for more information.
