Originial Lego Robot - 4WD, 4W steer, 5 spd transmission

This is a robot I have been working on for about a year. Eventually it will be totally autonomous and controlled via bluetooth, but for now it is simply a motorized chassis. Couple things to note - the dual-layered suspension (independent a-arms at each of the 4 wheels and independent a-arms linking the front and rear ends to the center. 3 differentials (front, rear, center) allowing any of the 4 wheels to spin independently - dicated by the level of resistance at each wheel. And of course the working 5 speed manual transmission.

Whats the NXT motors for that are not plugged in?

[zakeunc]

those were the motors that would control steering. the bot is drastically different from this now though. come back soon for an update! I guarantee it will blow your mind.

[animatorSimen]

use the xl motors instead, they're so f.... strong. The rc motors need a rc unit to not stop.

Dude, I would like to know how you bulit that tranny. I've been trying to bulid something like that, only 3 speed and reverse with neutral in the middle, just like a stickshift vehicle. Also for an engine, I'd use those pneumatic pumps and cyclinders.
