Help Needed with NXT

[That_LEGO_Guy]

My current build is using a PTO and pneumaticPTO transmissions from something unfinished (the unimog on my flickr if you are wondering): it has 3 motor inputs, 1 for selecting the output(there is 4 points/gears) and 2 to drive them, and 8 outputs.

current idea order may be switched around as all that is built are the 2 transmissions:

gear 1: left drive: left track right drive: right track

gear 2: left drive: pneumatic pump right drive: pneumatic valves (it can run 4 different valves from one rotating shaft)

gear 3: left drive: front pto right drive: second front pto

gear 4: left drive: rear pto right drive: second rear pto

So what I need it to do: control this from ether a laptop or smart phone via bluetooth.

the drive motors only need forward and reverse no variable speed needed

but the selector, there is 8 rotations between each gear/selections and 4 gears/selections, I need to, with an input, rotate 8 times then stop.

i.e. press the up direction key and the selector will rotate 8 times and stop, gear 1 to 2, press the down direction key and the selector will rotate 8 times in the opposite direction and stop, gear 2 to 1.

Hopefully this makes sense and is it possible?

You could do this via a PC or a Mobile phone if you can could. Look at NXTRemote for Android or MindSquall for PC

Or LeJOS allows PC control.
