an idea for the non-crushing states. make a soda can launcher to shoot the cans up and into the trashcan. There are many ways you could do it, springs, pneumatics, etc. the higher you shoot the cans into the air, the bigger a crowd you'll draw. extra credit for making the contraption as rube goldbergian as possible. super bonus points for making an electric one that uses induction to launch the cans.

One point here is that driving a robot around uses a lot of power. You might need to switch from motorcycle batteries to actual car batteries, as most unremarkable car batteries have 2x-5x the capacity of the batteries we use.
