School project robot ideas...

[dead5raka]

So I'm building this robot as a project for out computer class. The base is a Lynxmotion Tri-track platform (big, sturdy, powerful), i'm also using BS2 and two parallax hb-25 motor controllers. I have one ultrasonic rangefinder and two IR rangefinders, 2 servos and 2 continuous rotation servos.
Does any of you have any ideas about what i could build, and what would this robot do? I can't build something really big and complicated due to a lack of tools and equipment. I have some programming experience in pbasic (parralax's version of basic)

ideas are welcome
