Modern medicine promotes the design and creation of innovative ideas. The goal of this project is to further the research in MRI compatible actuators. The proposed actuator design, known as the PRiSM, uses directed pneumatic pressure to generate rotational motion. To confirm the validity of this idea, multiple tests were designed and conducted. These tests showed that, at 60psi, the PRiSM can operate open-loop with an angular velocity of 7deg/s, while exerting a torque of 435N/mm. Optimized conditions yielded an overall maximum angular velocity of 178deg/s and an overall maximum torque of 747N/mm.
