Finally a pic of the gearbox all done.
You can see the Atwood and the Drill both connected, and the pneumatic shifter in place (for high and low gears).
There are 2 of these on the bot - 1 for each side.
We’ve been driving the bot around for several days now…it’s a beast (it has had an encounter with a wall…lets just say the bot won)…In high gear (around 9fps) it can easily pull a 200 LBS person accross the carpet. In low gear (about 2fps) it is basically unstoppable
