This invention provides a robotic arm and surgical robot system. The robotic arm includes a suspension joint, a first joint arm, a second joint arm, a third joint arm, a motion detection mechanism, and a control unit. The first joint arm is mounted on the suspension joint and can move along a first arc trajectory. The second joint arm is mounted on the first joint arm and can rotate around a second central axis. The third joint arm is mounted on the second joint arm and can rotate around a third central axis and a fourth central axis, respectively. The motion detection mechanism detects the actual motion of each joint arm during the initial positioning. The control unit obtains the actual pose of the third joint arm after the initial positioning based on the actual motion of each joint arm, and controls the movement of the second joint arm based on the actual pose and the target pose for pose fine-tuning. By setting the second joint arm, the system meets the requirements of a large positioning space for the robotic arm and various surgical methods, reduces the size of the first joint arm, and improves the positioning accuracy of the operating instruments.
