Canada's Special Purpose Dexterous Manipulator or Dextre for Short having past its final exams in December is now officially on the job. It was 11 days ago that the Japanese H-2B Transfer Vehicle (HTV2) or as it is known as, Kounotori2, docked with the International Space Station with the help of another Canadian robot, Canadarm2.

After several delays Canada's robotic handyman named Dextre aboard the International Space Station (ISS) has passed its final exam and is now ready for full duties. Dextre, short for Special Purpose Dexterous Manipulator, was designed and built by MacDonald Dettwiler (MDA) for the Canadian Space Agency (CSA). Dextre along with Canadarm-2 on the ISS are known as the Mobile Servicing System (MSS).

Call it an orbiting Edward Scissorhands. Although Dextre's first major robotic work on the International Space Station this month was delayed due to a snagged truss, both the Canadian Space Agency and NASA anticipate it will replace spacewalkers for minor outside tasks during and after the station's construction.

Launched in 2008 aboard STS-123, the Canadian robotic hand - built by MacDonald, Dettwiler and Associates in Brampton, Ont. - was initially designed for astronauts to operate from inside the station.

See the steps of Dextre's final exam.

Working from his perch on the end of Canadarm2, Dextre will close in on his target, unbolt the first circuit breaker and remove it. He will then back up slightly to give himself more room to rotate at the waist in order to align his free hand with the second circuit breaker, and will grab it and slide it out. Afterwards, Dextre will move back again to give himself room to flip a second time so that he can align the first circuit breaker with the empty slot, and will slide it into place. He'll then return to the first worksite and replace the second breaker.

Dextre sera d'abord transporté à bout de bras par le Canadarm2 jusqu'à son lieu de travail et s'approchera ensuite de sa cible, déboulonnera le premier disjoncteur et le retirera. Puis il reculera légèrement, ce qui lui permettra de disposer de suffisamment d'espace pour pivoter à hauteur de la taille afin d'aligner sa main libre avec le second disjoncteur, qu'il saisira et enlèvera à son tour. Ensuite, Dextre reculera à nouveau de manière à pouvoir se tourner encore une fois pour aligner le premier disjoncteur avec l'orifice, puis le mettre en place. Finalement, il retournera à l'endroit où se trouvait le premier disjoncteur, et y installera le second.

Dextre est le robot le plus perfectionné jamais construit selon l'agence spatiale canadienne.
Il est d'effectuer des travaux courants d'entretien et de réparation, comme le changement de batteries et le remplacement de caméras à l'extérieur de l'ISS.

Leslie Sponder is an Operations Engineer and Mission Planner who works with the Special Purpose Dexterous Manipulator, or as it is better know as, Dextre.

Dextre is the most sophisticated space robot ever built according to the Canadian Space Agency. It is designed to help in maintaining the health of the International Space Station (ISS). Dextre's role is to perform maintenance work and repairs like changing batteries and replacing cameras outside the ISS or to assist in spacewalks.
