You also need to determine your use for the demo bot. Will you use it for young kids, high school students, and/or adults? T-shirt launchers are good for certain events, but if you are at a library it wouldn't be useful. Adults like seeing the workings of the robot, and young kids want something fun - shooting balls, shaking hands with the robot, etc.

We had this year's robot at a community event last night. The younger set liked catching moonrocks, the older students wanted to see a match, and a lot of the adults (at least engineering types) wanted to look at the motors and sensors.

Don't forget portability as well - we still our 2001 robot (which can shake hands - adapted from the ramp handle) because it is small and fits in a lot of regular cars.
