Abstract:
One exemplary embodiment is a system comprising an operator input device structured to move in response to operator-applied force and to selectably output feedback force to the operator. A first computing system is structured to receive input from the operator input device and provide an output. A second computing system is structured to receive the output and provide a robot control command subject to a force constraint. An industrial robot system is in operative communication with the second computing system and comprises a robotic arm structured to move in response to the command. The second computing system is structured process the output to impose a force constraint using a dual threshold hysteresis control. The first computing system is structured to apply a feedback force to the operator input device correlated to force associated with the industrial robot system.
