A telepresence controller is provided for interaction with a remote telepresence session to control haptic interactions between an end effector and the remote telepresence session. Force sensor(s) monitor force(s) applied to an end effector. Position sensor(s) monitor a position of the end effector. The telepresence controller communicates with the remote telepresence session to exchange position data and force data indicative of concurrent haptic movements of the end effector and an object in the remote telepresence session. Magnetorheological fluid clutch apparatus(es) have an input adapted to be connected to a power source and configured to receive a degree of actuation (DOA) therefrom, the magnetorheological fluid clutch apparatus(es) having an output being actuatable to selectively transmit the received DOA to the end effector by controlled slippage. A force controller module determines a force input required on the end effector as a function of haptic events for the object in the remote telepresence session. A clutch driver module drives the magnetorheological fluid clutch apparatus with the controlled slippage being as a function of the force input.
