Abstract
This application provides a robotic arm and a control method therefor. The robotic arm comprises a spatial positioning mechanism, a planar motion mechanism and a connection and rotation joint connecting the spatial positioning mechanism and the planar motion mechanism. The space positioning mechanism comprises a base, and a joint mechanism including multiple joints, with the joint at a head end thereof installed onto the base, and the joint at a tail end rotatably connected to the connection and rotation joint; a tail end of the planar motion mechanism is connected to a surgical instrument. Perpendicular line of a plane where the planar motion mechanism is located is perpendicular to rotation axis of the connection and rotation joint; and the intersection between the rotation axis and axis of the surgical instrument is an active remote-center-of-motion point, which facilitates setting of the active remote-center-of-motion point and reduces occurrence of multi-arm collision.
