Another wall avoiding robot with video.

(This video was a project for school. The robot wasn't but the actual video was. It shows how my robot works, and yes.. it only turns one direction. I am still on a budget.)

Please leave suggestions on how to improve the robot. I also need somehelp on ideas to improve the chassis. Thanks!
