Abstract

According to one exemplary embodiment, a manipulator device includes a base, first and second linear slides, a drive link, a drive member, a driven member and an end effector. The elements of the manipulator device cooperate to constrain the end effector to rotate about a remote center of motion that is displaced from a proximal center of motion as the drive link moves a carriage of the second linear slide along an arcuate path.
