I was toying around with something like this. A foot like thing would come
down, lift the whole vehicle up off the ground, then turn it right or left 90
degrees (maybe even a variable angle), and set it back down. It does look like
a three motor problem. It would be nice to pull it off with only the parts in
the box. It doesn't need to go backwards, perhaps the drive motor could power
the foot down when it is in reverse.
