Scalability
- Mechanically, this can be scaled up to whatever size stepper motor is available. with proper geometry, allowed forces can be large.
- Basics: if we have a 50lb force with a 1/2" pulley and 15mm GT2 belt - we can get to 500 lb pull readily on a 5" pulley! Good forces are allowed. We can probably get 5 kg load on the end effector for an industrial welding robot.
