E-puck

E-puck is a small robot that can be programmed to do different tasks. It has wheels, a few lights, a few sensors, and a small processor. You can connect it to a computer and use a special program to give it instructions. For example, you can use it to make it go forward, backward, turn around, and even make decisions based on what it detects with the sensors, like avoiding obstacles.
