(Hm...very interesting, Dr. Watson. The mystery will be solved in Houston.)

Torque and Speed are directly related if you look at a Torque-Speed curve of a motor. As one goes up, the other goes down. Torque is the pushing power of the robot. It is also what causes the acceleration of the robot.

With that said, using 4 motors, a lot more torque can go to the wheels, causing the robot to accelerate much faster. Even though they have the wheels geared rather high, they get up to speed rather quickly. Once they get up to speed, torque isn't a factor, so speed takes over, which allows them to go rather fast.

It's more complex that that, but that's the gist of it.


As for hooking up two motors in unison, it's not unheard of. We (269) have 2 chiaphua motors connected in unison on our transmission for the differential. It's needed for our car-style steering, which allows us to move in radial and linear movements much like 16. Although we are not as fast as 16, our radial motion allows us to get to the wall faster than ordinary robots.
