The CORVUS Arm (Complete Operating room Robotics for Virtually Unassisted Surgery) is a 6 degree of freedom robotic arm (shown below) with a PRRRRR setup (a prismatic joint followed by 5 revolute joints in series). The prismatic (linear) joint runs along the side of the operating room (OR) table from the head to toe. Currently there is one CORVUS Arm on each side of the OR table. This setup allows a reachable workspace that covers the entire patient. The arm could hold any tool at the end, and could also perform tool changes during a surgical operation. The CORVUS team currently includes John O'Neill and Jason Lu.
