Abstract

A system and method for movement control includes a controller coupled to a computer-assisted surgical device having a first movable arm coupled to a manipulatable device having a working end and a second movable arm coupled to an image capturing device. The controller is configured to receive first configurations for the first movable arm; receive second configurations for the second movable arm; receive a plurality of images of the working end from the image capturing device; determine a position and an orientation of the working end; determine a first movable arm position and trajectory for the first movable arm; determine a second movable arm position and trajectory for the second movable arm; determine whether motion of the movable arms will result in an undesirable relationship between the movable arms; and send a movement command to the first or second movable arm to avoid the undesirable relationship.
