Instructiuni

The line-tracking mouse is an excellent, low-cost robot for someone who has previous soldering experience and would like to get started with robots. This kit features two independent gearboxes, two printed circuit boards, a plywood base, and a clear, mouse-shaped body.

This kit includes three infrared sensors along the bottom of the robot and a microphone that allows you to start the robot by clapping or tapping its body. Three LEDs show you what the robot “sees”, and two other LEDs light up when their corresponding motors are on. The mouse runs off of four AA batteries.
