Medical robotic systems can make surgical and rehabilitative interventions more efficient, accurate, accessible, and reliable while reducing the burden on health care systems. The need for such robotic technologies stems from the current long wait times for surgeries, therapies and rehabilitation sessions. Surgical, therapeutic, rehabilitation and other medical interventions can be...

This 2 DOF Ball Balancer experiment demonstrates how a camera can be used to measure X-Y position of a ball on a flat surface and then use these measurements to stabilize the ball to a desired position on the balance plate. In this example, we are using a Proportional-Derivative (PD) control but you can add the Integral control for a full PID control loop.
