Drivetrains in Ultimate Ascent

[mathking]

1014 is using six (4") wheel drive, with two omni wheels at the front (as determined by where discs are released) and two pairs of traction wheels, one pair in the middle and one in the back back. With tougbox mini at a 12.75:1 ratio. It is not fast but is very maneuverable and has good pushing power. No drop center. The omni wheels allow the robot to turn almost in place.

We're running 4WD WCD, direct-driven via VexPro single speed gearboxes and a 2nd VexPro gear stage to 4" AM Performance wheels. Can't remember what the final ratio is, but the speed is roughly 11.6ft/s before losses. The wheelbase is 30" wide x 18.5" long. Center of Gravity is biased 4" forward of front/rear center, and is nearly perfectly balanced left/right. It took us 1.5 weeks to fab it, and most of that was waiting to figure out what the frame would look like due to climbing and/or floor pickup. It weighs only 24.5 lbs and cost less than the kitbot because we made everything in-house.

Man does it fly too.
