This paper presents Gateway Configuration as a new concept for fast operation of a Scara parallel robot with low energy consumption. The mechanism and its kinematic problem are presented together with dynamics model. The control scheme presented consist on a conventional PID and a pre-feedforward term. For a specific trajectory we have compared the results of a conventional configuration and two gateway ones. The simulated results demonstrate that Gateway Configurations provide a high-quality end-effector position tracking with a very low energy consumption. Although results are presented for a particular trajectory, in the case of a Scara parallel robot multiple trajectories can be found in terms of Jacobian matrix and elbows mechanism distance. The results presented here allow to design an ultrafast manipulator for pick and place operations.

Abstract
This paper presents Gateway Configuration as a new concept for fast operation of a Scara parallel robot with low energy consumption. The mechanism and its kinematic problem are presented together with dynamics model. The control scheme presented consist on a conventional PID and a pre-feedforward term. For a specific trajectory we have compared the results of a conventional configuration and two gateway ones. The simulated results demonstrate that Gateway Configurations provide a high-quality end-effector position tracking with a very low energy consumption. Although results are presented for a particular trajectory, in the case of a Scara parallel robot multiple trajectories can be found in terms of Jacobian matrix and elbows mechanism distance. The results presented here allow to design an ultrafast manipulator for pick and place operations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
