The Robot Torque Arm Calculator is intended to help you choose the right motor for each joint of your robotic arm. The torque (T) required at each joint is calculated as a worst case scenario (lifting weight at 90 degrees). Ensure your units are consistent. Most common units are kg-cm and oz-in. Take a look at the Tutorial for more information. L: length from pivot to pivot. M: link mass A: Actuator (servo or other) mass. Note: same units as for link masses. A1 can represent the load being lifted. Use the image above to help you determine which torque corresponds to which joint. Note the numbering starts with the extremity of the arm, so the final torque is the one lifting the entire arm. The torque shown is the STALL TORQUE you can use for your search. Lowering the overall efficiency increases the required torque at each joint.
