Abstract
The problem of minimum joint torque motion is considered in the low-level control. The optimum motion is obtained by a local optimisation that uses the calculated derivatives of the cost function represented as a square norm of the joint torques. The experiments are carried out with planar mechanisms lifting loads. It is shown that standard control schemes which include simple singularity-avoidance algorithms and limited joint velocities can be used for this purpose.
