Robot system
Robot system which includes a master device configured to receive an operating instruction from an operator, slave arm, storage device configured to store operating sequence information that defines processing carried out by slave arm, and control device configured to control operation of slave arm. Control device includes a receiver configured to receive an input signal, motion controller configured to determine whether operating mode of slave arm is to be automatic, manual or correctable automatic mode and control operation of slave arm in determined operating mode, and continuation determinator configured to determine whether continuation of automatic mode is permitted. In a process at which slave arm is scheduled to operate in automatic mode, after motion controller suspends operation of slave arm in automatic mode at a given step of process, continuation determinator determines whether continuation of automatic mode is permitted based on input signal received by receiver when operation is suspended.

MULTIMODE CONTROL SYSTEM FOR MAGNETORHEOLOGICAL FLUID ACTUATOR UNIT
A control system is provided for controlling movements of an end effector connected to a clutch output of at least one magnetorheological (MR) fluid clutch apparatus. A clutch driver is configured to drive the at least one MR fluid clutch apparatus between a controlled slippage mode, in which slippage between a clutch input and the clutch output of the MR fluid clutch apparatus varies, and a lock mode, in which said slippage between the clutch input and the clutch output is maintained below a given threshold, the clutch output transmitting movement to the end effector. A motor driver is configured to control a motor output of at least one motor, the motor output coupled to the clutch input. A mode selector module is configured to receive signals representative of at least one movement parameter of the end effector, the mode selector module selecting a mode between the controlled slippage mode and the lock mode of the clutch driver based on the signals, and switching the selected mode based on the signals. A movement controller controls the clutch driver and the motor driver to displace the end effector based on at least one of the selected mode and on commanded movements of the end effector for the end effector to achieve the commanded movements. A method for controlling movements of an end effector connected to the MR fluid clutch apparatus is also provided.
