Abstract
A control method for a surgical robotic arm, a computer device and a surgical robotic arm are provided. The control method includes calculating a telecentric fixed point on an executing rod according to a target point and controlling a preoperative positioning assembly to advance a first movable platform of a telecentric manipulating assembly along a first coordinate axis of a movable coordinate system; calculating a first origin coordinate of an origin of the first movable platform in a stationary coordinate system according to the coordinate of the telecentric fixed point and the trajectory coordinate of an end point; calculating the length of a first telescopic element of the telecentric manipulating assembly according to the coordinates of a hinge point of the telecentric manipulating assembly in the stationary coordinate system; and controlling the first movable platform to move to a designated pose.
