Learn how to build and code a high-performance wall follower. The wall follower can negotiate complex positive and negative turns at high speeds. We are using LEGO Spike Prime with VL53L0X time-of-flight laser distance sensors. An LMS-ESP32 board translates the i2c signal from the sensors to something Pybricks can read and work with. This video is a full building and programming guide.
