Battery goes underneath with two friction drive motors that attach to back wheels. which allow left right forward or back motion. front wheels drift in any direction as you would expect. Driver sits in cart and controls via blutooth ap. Steering is achived by powering on the left or right motors. kit comes with a livetime warranty or 3 months which ever comes first.

You'd have to stop the rear wheels castoring, otherwise it would just go in random directions.

The motors and powerpack from a "hoverboard" could be a good starting point for the propulsion system.

Oh, and what [FT] said ...
