Abstract
A surgical robot arm comprises a base connected to a terminal link () via a series of intermediate joints. The terminal link () comprises a drive assembly interface comprising drive assembly interface elements (). Each drive assembly interface element is configured to: engage an instrument interface element () of an instrument interface of a robotic surgical instrument when the surgical robot arm engages the robotic surgical instrument; and move relative to the drive assembly interface across a range of motion so as to, when engaged with the instrument interface element, transfer drive to that instrument interface element. The drive assembly interface elements are arranged across a plane perpendicular to the longitudinal axis of the terminal link such that the robotic surgical instrument is detachable from the surgical robot arm in a detachment direction parallel to the plane when each drive assembly interface element is anywhere within its range of motion.
