Abstract
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.
