Dextre resembles a gigantic torso fitted with two extremely agile, arms. Total mass is about . The 3.5-metre-long body pivots at the "waist". The body has a Power Data grapple fixture at the 'head' end that can be grasped by the larger Space Station Arm, Canadarm2 so that Dextre can be positioned at the various Orbital Replacement Unit (ORU) worksites around the Space Station. The other end of the body has a Latching End Effector virtually identical to that of Canadarm2, so that Dextre can also be attached to Space Station grapple fixtures or the Mobile Base System.
