Re: Gearing That Cannot Overcome Static Friction

we dont know what the game will be this year, but high speed may not be what you need.

Remember a few years back, teams pulling two mobile goal platforms around with one robot - geared down to speeds like 6 inches per second, and lifting the goals in the air to get extra traction? Maybe thats what they are thinking - several gears to get very low speeds with super pushing power, and everything in between up to a normal 10 or 12 F/S?

Making a transmission that shifts quickly is part of the challenge.

One other thing Ive noticed - Ive yet to see a FIRST transmission that has a clutch, like a car does. Im sure they didnt have torque converters either, so how they get away with shifting under power, with no clutch, is beyond me!

I can do it with my car, by matching the engine rpms while I upshift - but that has taken years of practice to accomplish without mashing the gears.
