Beutiful robot, of course. I'm curious as too what motors you guys used in the drive train and how fast the 'bot goes. Also did you reverse one of the drill motors so as to get an equal amount of power out of them?
This season, our drivetrain is very, very simple; at least, by our standards.

If you're familiar with our drivetrain from last season, you'll understand that we focused exclusively on building a powerful, versatile design that brought us great success.

This season, we opted to focus on other parts of the robot, and we simplified the drivetrain slightly.

We're using the Bosch motors, mounted in the provided mounts. Their transmissions are locked in high gear. The output of the provided transmissions pass through a shift-on-the-fly transmission based heavily on the White Paper provided by Dave Lavery and Team 116 for a two motor, shifting transmission.

We decided tp use a single motor per side to save weight and because our strategy called for maneuverability over power.

Our top speed, after a 1:3 reduction from the motor's output shaft (1:1 in the transmission, then 1:3 with chain and sprockets) is approximately 8 ft/s. Our low speed, after a 1:9 reduction (1:3 in the transmission and 1:3 with chain and sprockets) is approximately 3 ft/s.

We didn't reverse the drill motors and we have corrected for offset in power with programming. Admittedly, however, we were very surprised to see just how noticeable the difference is.
