Im going to attempt to describe how this works in words...bear with me. I'm not sure how familar you are with a snowmobile transmission works but this is on variation of it. What I've done is have the motor spin the cone shaped object. This cone will spin a timing belt. and depending on the power needed by the robot the belt will slide up and down the cone. The spool shaped object is the output shaft to the wheel/track/etc. This whole system works of the tension of the springs and the belt and is mechanically automatic. The green thing is the tensioner on the belt. Currently this is my last ratio only because I don't believe a belt could handle the high RPM of the atwoods(my team only uses the atwoods in the drivetrain).

Please keep the questions coming...

-Thanks
