How can I make a cheap semiautonomuos robot?

Just for referance I would like to make a semiautonomous robot for around $150.  I would like to have the robot to where it could make desitions on its own or I could flip a switch and control it by RC.  I would like it to be on wheels and make it programable.  Can someone help me?

The answer will greatly depend on to what extent you want it to be able to "make its own decisions". Driving around randomly and avoiding bumping into things isn't that hard, but intelligently navigating a space is much more complex.

You might start looking for something similar to your idea from the robot contest held a while back.
