What this robot can do: TriBot is a flexible and fast 3-wheeled driving robot! It takes advantage of all four sensors to do the job you program it to do. TriBot can grab a ball when you give it a sound command (through its Sound Sensor ), can be programmed to follow a line with its Light Sensor , can feel objects with its Touch Sensor , and can see with its Ultrasonic Sensor . Build TriBot’s driving base in just 30 minutes with the QuickStart Guide! (Included in the LEGO Mindstorms NXT kit) See how easy it is to program TriBot to follow a line You’ll need to attach TriBot’s Grabber (instructions in the LEGO MINDSTORMS NXT Software Robo Center).

This simple program enables TriBot to power 1 motor when the light sensor detects dark, and a second motor when the light sensor detects light. Use this program to have TriBot follow a line, modify it, or create one of your own!
