A common, cheap cordless drill available here from the local large hardware store (bunnings) is the 14.4v “XU1” (not to be confused with the history-making car). The same shop also sells plastic trolly wheels with rubber tread that fit perfectly onto the output shafts of these drills.
Does anybody have any opinions on using a TReX to drive a pair of these? I dont have the exact specs on hand of the drill, but there are many other nearly identical drills being used for robotics - i am sure somebody has an opinion. I will be looking at driving it from a pair of 12AH 6v SLA’s, providing 12v to the motors
