MIYBot is a educational robot that I have been working on for many years. MIYBot is a robot circuit board that makes it much easier to build a robot. It uses a Adafruit Trinket Pro as a brain, HC-SR04 ultrasonic sensors, Pololu line sensors, and continuous rotation servos for motors. In the fall of 2015, I wrote extensive documentation for the MIYBot as a project for a grad school class at Georgia Tech.
The thing that sets this apart from others is that it allows for the robot builder to design the wheels and body for their own personal robot. In fact, I had 7th graders build 70 or so MIYBots during the Spring of 2016!
