🦾 Robot Arm: Gravity Torque, Payload Capacity and Motor Limits (2D)

Side view of a three-joint robot arm holding a payload, with each joint coloured by how close its motor is to its torque limit. Set the shoulder, elbow and wrist angles, the payload, the joint acceleration, the size of the arm and the shoulder torque limit, and see the holding torque and the acceleration torque at each joint, the most loaded joint and the largest payload the pose allows. Virtual work, the inertia matrix, the payload limit and the work done against gravity are checked numerically, with four in-page numerical checks.
