This video demonstrates my first successful robot. It consists of a Basic Stamp microcontroller, a snap circuits car, and the head of a toy robot. A servo motor rotates the head, which contains infrared sensors to detect obstacles. The motors are controlled by relays, and their power supply is completely separate from the rest of the system. The robot is surprisingly good at detecting obstacles, but as you can see in the video, it tends to get stuck in corners.
It seems to default to the right when it detects an obstacle, so making it turn 90 to the right instead of left when it backs up should eliminate that issue.
That's a good idea, thanks! I'll try changing the code to fix that.
