This remote control program uses two sliders (one for
speed and one for steering) to control the twin cars together as a pair.
It controls all four motors individually and does the calculations to
apply the appropriate motor speeds given the geometry of the model.
This alternate remote control program uses a D-pad for
the basic movement directions and also adds two additional buttons to
execute "gate" turns. One advantage of this type of control vs. a pair
of sliders is that you can use it with one hand or just a mouse from a
computer without multi-touch.
