Abstract

The authors propose a trajectory-planning algorithm to minimize the maximum torque required to produce a prescribed trajectory with a pick-and place robot. This is done with a scheduling of the velocity of the moving plate, while following the Adept path. Simulation tests are conducted with the dynamics model of an isostatic Schönflies-motion generator, but the proposed algorithm can be applied to any architecture capable of producing Schönflies motions. Results show a reduction of more than 40 % of the maximum torque required from the actuators, regardless of the cycle time, when traversing the path at 1 Hz and higher.
