Let's Make Robots!

tractor-trailer coupling with power transfer

This is an idea for two (or more) cooperative robots. One passive bot (with wheels, but without motors) and one active bot (with motors). The motor-bot (the tractor) would pull the lame bot (the trailer). The trailer has a power source on board. The tractor wants to recharge its battery from that source.

The big idea is so big, I won't even mention it here. Yet.
