Abstract
Disclosed is a surgical robotic system comprising a robotic arm holding an end-effector and a control unit for controllably moving the robotic arm and maintaining the end-effector in at least one target position relative to a patient. The control unit can, based on a first input continuously applied onto the robotic arm, activate a hand guiding mode wherein the robotic arm is freely movable by the user; based on a second input different from the first input, continuously applied onto the robotic arm, activate a computed trajectory mode wherein the robotic arm moves to a target position according to a computed trajectory; when the computed trajectory is activated, detect that the end-effector meets a predetermined safety condition and automatically switch to a servo-controlled mode wherein the robotic arm is automatically movable to maintain the end-effector in the target position relative to a tracker attached to the patient.
