That is a good gearbox, but you do NOT want your robot to go 20 ft/s. You really, really won't be happy with the results. 20 ft/s is far too fast to control easily. You'll find yourself constantly shifting into low gear to do pretty much anything. You should really aim for a top speed of no more than 14 ft/s.
