Abstract: A system for assisting a user in moving a device relative to a structure comprises a magnetorheological (MR) fluid actuator unit including at least one torque source and at least one MR fluid clutch apparatus having an input coupled to the at least one torque source to receive torque from the at least one torque source, the MR fluid clutch apparatus controllable to transmit a variable amount of assistance force via an output thereof. An interface is configured for coupling the output of the at least one MR fluid clutch apparatus to the device or surrounding structure. At least one sensor provides information about a movement of the device. A processor unit for controlling the at least one MR fluid clutch apparatus in exerting the variable amount of assistance force as a function of said information, wherein the system is configured for one of the MR fluid actuator unit and the interface to be coupled to the structure, and for the other of the MR fluid actuator unit and the interface to be coupled to the device for the assistance force from the MR fluid actuator unit to assist in moving the device.

Abstract: A system for assisting a user in strength training with a strength training device comprises a torque source. One or more magnetorheological (MR) fluid clutch apparatuses has an input coupled to torque source to receive torque from the torque source, the MR fluid clutch apparatus controllable to transmit a variable amount of torque via an output thereof. A modulation inter face couples the output of the at least one MR fluid clutch apparatus to a force transmission of the training device. One or more sensors provide information indicative of a training action by the user. A training processor comprises a training effort calculator module for receiving the information indicative of the training action and for characterizing the training action, a training assistance controller module for determining a level of force assistance from the characterizing of the training action, and an assistance generator module for controlling the at least one MR fluid clutch apparatus in exerting the force assistance at said level on the force transmission of the training device to assist the user in the training action. A method for assisting a user in strength training with a MR fluid clutch apparatus is also provided.
