We have collaborated with Stanford University researchers to utilize our patented hybrid hydrostatic actuator for the development of MRI-safe surgical robots. Robots developed with this actuator design can be constructed entirely out of plastic, making them inherently safe in high magnetic and electrical noise environments.
The novel toroidal piston and arced rolling diaphragm design enable a compact form-factor that can be scaled to meet any torque requirements. The use of pneumatic and/or hydraulic fluid provide the added benefit of precision force feedback, making it the well-suited for surgical and human-interaction use.
The study has been published in IEEE Transactions on Medical Robotics and Bionics and is available here.
