It works quite well, actually. Using chain drive (instead of gears or belts) makes it tolerant of small misalignments which lets us use the robot frame to locate the components. That saves weight over a self-contained transmission assembly.
Shifting is very positive. and using a single air cylinder and linked clutches makes sure both transmissions are in the same gear.
We built a speed sensor circuit to give more positive speed control and allow us to go to automatic shifting, but ran out of time and weight to put it on the robot. Something to add next year.
