Publication number: 20160096271Abstract: According to some embodiments of the present invention, a cooperatively-controlled robot includes a robotic actuator assembly comprising a tool holder and a force sensor. The cooperatively-controlled robot further includes a control system adapted to communicate with the robotic actuator assembly and the force sensor, and an actuator in communication with the control system and mechanically coupled to a tool. The force sensor is configured to detect a vibrational force applied on the tool and send a signal to the control system based on the vibrational force. The control system is configured to receive the signal and determine a force to apply to the tool to damp the vibrational force. The control system then signals to the actuator to apply the determined force, and the actuator applies the determined force to actively damp a vibration of the tool.Type: ApplicationFiled: October 6, 2014Publication date: April 7, 2016Applicant: The Johns Hopkins UniversityInventors: Russell H.

Publication number: 20140360305Abstract: The present invention is directed to a tool holder for use with a surgical robot. The tool holder includes, a rotor fixed to the tool shaft, and a stator fixed to the robot. The stator includes a magnet, and a bearing surface. The rotor includes a magnetic material that attaches securely to the tool shaft, such that the tool is in the center of the rotor. The rotor rotates against the bearing surface on the stator, allowing the tool to rotate about its axis. To exchange tools, the user exerts force on the tool until the holding force of the magnet is exceeded and the tool detaches from the stator. A new tool is introduced into the vicinity of the stator such that the magnet attracts the magnetic material on the rotor. The present invention eliminates the need to slide the tool through a shaft of the tool holder.Type: ApplicationFiled: June 9, 2014Publication date: December 11, 2014Inventors: Kevin Olds, Russell H.
