Maximum Weight for robot
Posted: Wed Jun 03, 2015 7:29 pmIf I wanted to make a robot, how do I determine the maximum weight it can carry if I know the motor's torque rating and the size of my wheel?
rotating torque normally calculate in kg-cm, or Nm, or other unit. Let's take kg-cm, say a motor with the torque of 12kg-cm, this means the motor is able to turn 12kg if the load is 1cm away from the center shaft. If your wheel is 10cm, so it can only drive 12kg/10 = 1.2kg only. That is on book.
The actual case, there is a lot of friction which will reduce the total torque.
