The present disclosure describes a method and system for performing robot-assisted surgical procedures. The system includes a robotic arm system assembly, an end effector assembly, and a hybrid control mechanism for robotic surgery. The robotic arm is a lightweight, bedside robot with a large range of motion, which can be easily manipulated to position endoscope and surgical instruments. The control console is mounted at the distal end of the robotic arm to enable robotic arm to follow operators arm movement, provide physical support, filter out hand tremor, and constrain motion. A universal adapter is also described as an interface to connect traditional laparoscopic tools to the robotic arm.
