Robot wheel torque to weight calculation help
It's been a while since I've had a physics class and I'm scratching my head to remember how to figure out the following problem. If I have a pair of motors for a robot wheeled base that have a torque of 6 lb/in each and, lets say, a 5 inch wheel, how heavy of a robot can I build? I'm starting to build a robot base that I would like to future proof so I can add extra electronics and hardware and start with a battery with plenty of power (which of course means more weight). I'd like to avoid building the robot and find out later that the motors don't deliver enough force. Any ideas?
