Science Buddies: "Ask an Expert"

I have to submit a science project in a month, and I don't know what to do. I've chosen Physics, and I'm thinking of making a robot, but the materials are hard to get. Suggestions? Or other ideas?

HealDWorld,

The key is to pick a subject you are interested in. For ideas or inspiration, check out the project ideas area of the forum at this link:

There are several robot projects that you can take a look at (and so much more). For a cheaper robot with easy to get components, take a look at the bristlebot idea.
