Abstract
A teleoperated MRI compatible arm system is provided that allow a physician to remotely operate. The system is passive, meaning forces and motions are generated by the operator and the device transmits them through a low-friction hydraulic transmission to the output end. The device enables manipulation in seven axes and exhibits one-to-one motion, allowing the physician to position and orient the needle during insertion. Moreover, the system is back-drivable and passively reflects patient respiratory motions and forces, a major roadblock to other devices explored in this space. The configuration of degrees of freedom and inputs allows the manipulation arm to maintain contact with the skin while also allowing the operator to insert the needle.
