Autonomous Robot Racer: Scratch Mode

In this project, you’ll learn how to make an autonomous wall-detecting robot. This robot uses an Arduino Nano and Scratch to avoid walls and race around the track. The Tompkins County Public Library uses this robot to hold weekly robot racing events. This is one of several autonomous robot racers developed at TCPL. More robot Instructables coming soon!
