A surgical robot and a control method and device for a robot arm (21) thereof. The surgical robot includes the robot arm (21) and the control device, the control device is configured for acquiring an external force applied on a power mechanism (22); acquiring an input operating command for task degrees of freedom of the power mechanism (22); combining the task degrees of freedom to analyze the external force to obtain target position and/or pose information of the power mechanism (22) at a base coordinate system, according to the target position and/or pose information, controlling a movement of joints of the robot arm to allow the power mechanism (22) to move within corresponding degrees of freedom. The operating command includes a completely matched first operating command, and a partially matched second operating command. The power mechanism (22) of the surgical robot can be precisely freely dragged or constraint control dragged.

A translatable end effector for a surgical robot includes a pair of linkage arms, an anchor adapted to be mounted to an arm of the surgical robot and a tool holder connected to the anchor through the pair of arms. The hinges at the anchor are pivotally and slidably coupled to the pair of arms to allow the arms to pivot and slide relative to the anchor hinges. The tool holder is configured to hold a surgical tool and has a pair of hinges that pivotally couple to the ends of the linkage arms. The hinges and the linkage arms are configured such that a longitudinal trajectory defined by the surgical tool is maintained as the tool holder translates upwardly and downwardly relative to the surgical robot arm.

A robotic snake comprising a plurality of friction anchors, a plurality of segments and a plurality of servo motors are disclosed. Each of the plurality of segments includes a first link and a second link connected at a first joint, a third link connected to the first link at a second joint, a fourth link connected to the second link at a third joint, a fifth link connected to the third link at a fourth joint. The simultaneous rotation of third link and fourth link of each of the plurality of segments results in a translational movement and/or a rotational movement. A plurality of servo motors is configured to rotate plurality of joints. The fifth link of one segment and first link of next segment of the each of the plurality of segments act as a quaternary link serially connects each of the plurality of segments.
