Dextre [Special Purpose Dexterous Manipulator] is designed so that only one arm can move at a time in order to avoid self-collision, achieve greater stability and maintain operational similarity with Canadarm2. The greater stability is provided by the immobile arm, which is first commanded to anchor Dextre to an ISS [International Space Station] stabilization point. At the tip of each arm, we find a "hand", known technically as the Orbital Replacement Unit/Tool Changeout Mechanism (OTCM). The OTCM consists of a set of parallel retractable jaws, which serve to grip payloads and tools. Each OTCM is also equipped with a retractable motorized socket wrench to mate and demate mechanisms on-orbit, as well as lights and a black and white camera. Dextre lower body is equipped with a pair of pan/tilt colour cameras that allow astronauts aboard the ISS, and engineers on the ground, to monitor the task, which is out of direct eyesight. 1, record 4, English, - orbital%20replacement%20unit%2Ftool%20changeout%20mechanism

Dextre [Manipulateur Agile Spécialisé] ne peut toutefois bouger qu'un bras à la fois afin d'éviter les autocollisions, d'assurer une plus grande stabilité et de conserver une similarité opérationnelle avec le Canadarm2. Sa grande stabilité lui vient du bras immobile qui est commandé pour ancrer Dextre à un point de stabilisation sur la Station spatiale internationale dès le début des activités. Au bout de chaque bras se trouve une «main», que l'on désigne techniquement par changeur d'outils et d'unités remplaçables sur orbite (OTCM). L'OTCM comprend un ensemble de mâchoires parallèles rétractables servant à la préhension de charges utiles et d'outils. Outre des lampes et une caméra noir et blanc, il est également équipé d'une clé à douilles motorisée et rétractable pour accoupler et désaccoupler des mécanismes sur orbite. La partie inférieure de Dextre est dotée d'une paire de caméras panoramiques basculantes couleur qui permettent aux astronautes de la Station et aux ingénieurs au sol de surveiller l'exécution d'une tâche qui ne se trouve pas directement dans leur champ de vision. 1, record 4, French, - changeur%20d%27outils%20et%20d%27unit%C3%A9s%20rempla%C3%A7ables%20sur%20orbite
