All very entertaining folks. At 2 cents for each opinion, it still adds up to only about a buck two ninety-eight? So I'll add mine to round out the mix.

Not enough emphasis on the "loco" part of the motion. Let's try off-center special wheels that will truly supply loco-motion and the chugga-chugga motion like a railroad train as in the song lyric. It won't matter if the playing field is level. All the robots will be bopping around.

I hope you all bought a good supply of pool noodles as Bill advised way long ago.
