help with robot project

hi i'm doing a project for my school and decided to do robot. i've search on the internet but i culdn't find anything, what i want to do is a car robot with sensors that avoid things, or maybe just radio control car. thanks for your help :wink:

i hope you can help me.

To avoid obstacles, you may use bumpers or light sensors (included IR) or ultrasonic sensors.

However, I suggest you to use bumper for beginning. It's easy to build.

As the bumper kick the obstacle, you turn your robot to the opposite side, and continue travelling. It's first base of RUGWARRIOR robot. It's famous. You may follow it. Search on google for details. I don't remember the site.
