Re: pic: New Drive System for 703
Billfred is right on track. 703 has not used chain or belt in our main drive system since 2003. We love the reliability and ease of maintainance that comes with an all gear drivetrain. Could we have done the same with a 6WD and got most of the benefit? Sure. But then we would have needed a whole bunch of idler gears to get the power from the gearbox to the front and back wheels. Besides, we wanted to keep all of the charactoristics of our treads but not have any broken belts. This does that. And it is cool.

The weight is a little more than our previous system. We figure that the running chassis with all the motors, wiring, controls, and battery will be about 52lbs before we add any game playing features. We're not worried about it for this year's game.

The cost is actually less that the breco-flex belt system we have used in the past. The gears are cut from pinnion stock, and we make all the wheels in our school shop.
