Reddit user asks for help calculating robot arm joint torque to select servos
1 reports · 1 sources
A Reddit r/robotics poster asked how to calculate the torque for each joint of a robot arm using J=mgr (in kg.cm) in order to choose suitable servos for each joint, and gave the conversion 1 N·m≈10.1 kg·cm. The post only lists the theoretical formula and does not give the robot arm model, number of joints, or measured data; the poster hopes someone can guide them on how to apply the formula to a specific project, or recommend a YouTube video that explains the basic concepts.
