This tiny little robot packs 4-Wheel drive plus a extra third motor for expansion all into a very compact package that makes for a very small robot that can maneuver in very tight spaces. Two motors with gears drive all four wheels using "Skid Steer" to turn, and the third motor is hiding inside and drives a shaft that pokes out to drive an arm or other accessory that you can add. See the Mini Forklift as an example.

You can drive this robot with the standard remote control ("Drive") function, or you can take a look at the two programs provided here that show different and unusual ways to move. Study the programs to see what you can learn from them.
