Is a shifting transmission really necessary?

John,

We design for a higher max current draw. With the addition of the little blue battery this year it is possible to increase the max current draw of the drive system without putting the controller to sleep if you momentarily drop under 8 volts.

Our efficiency is such that we can achieve 10 ft/sec. max speed (which is all we feel we need) and we are also able to break all four knobby pneumatic tires loose at the low end.

In 2003 we had a 4 motor system with a robot weighing 115#. This year we weighed 130# and had a 6 motor drive.

You are extremely correct: It is important to get there fast. Once you are there, you want to be able to stand your ground. We have been able to accomplish both with a one speed gearbox.

Thanks for the comments all,

Jay
