Independant drive to the two treads in the set will work, power one forward
and the other backward and you'll spin on the spot - depending on carpet
properties!

Paint your ceiling white, point the IR tower upwards and bounce the signal
off that. Works well for me in a room 7m x 4m with an "artex" (ie rough)
ceiling - despite what the manual says about line of sight and max distances
(although you do need a fresh battery in the IR tower)
