Converting the tank drive commands to velocity and steering would not be too hard.

Velocity = (L + R) / 2
Turn      =  (L - R) / 2

Though, the cart won't react the same way as a First robot.
Mainly because the cart can't turn in place, only in arcs.

I would keep the steering control type as close to the original as possible (ie a turn-table would be fine because it is still a type of rotary interface that has a one-to-one relation with the cart's steering, like the original steering wheel)
