After an eight - hour dance in microgravity , Dextre and the Canadarm became the first ego - amend machinelike arrangement in space , replacing a faulty camera without pass on orbit or relying on annoying spaceman .

TheCanadarm , Dextre , and roving alkali stations work together as arobotic systemattached to the International Space Station . Dextre , the weapon system ’s independent robotic hand , was fleece and plopped into position by the Canadarm to delicately substitute a faulty television camera on the subdivision ’s elbow .

One of the camera at the branch ’s elbow - juncture has been produce fuzzy images . It ’s still running , just not idealistic . So in an eight - hour distance - dance , Dextre swapped it over to a less - critical location at the mobile radical . Tuesday , he will think a fresh camera from the air lock , and install it as a replacement on the arm ’s elbow .

The Canadian Space Agency free an vivification of the game - plan :
From the caption , the plan was :
Dextre will start by retrieving a faulty tv camera turn up near Canadarm2 ’s elbow joint . Since the camera is functional , but produce hazy images , Dextre will move it to a less critical location on the mobile base . Dextre will then head over to Japan ’s Kibo mental faculty to fetch a camera from the mental faculty ’s transference airlock — a eccentric of sliding drawer that can be depressurized — where the station ’s gang will place it for Dextre to regain . Dextre will set up the new camera on Canadarm2 ’s elbow joint , where it will provide decisive view of the robotlike sleeve ’s movements .

Dextreis an amazing robotic handyman who all deserves his own article explainingjust how neat he is , but the short variation is that he ’s referred to by the masculine pronoun , he has two limb , with 15 joints yield hima staggering 15 degrees of freedom . And , to the best of my knowledge , he does not have a crush onCuriosity , although I depend they ’d be the best of friend .

Of course , nothing go perfectly . Yesterday , Dextre selectinga pecker from his holster , and the Canadarm pluck him from the station to swing in outer space . Today , he begin in on the repairs , but had to take a break when thestation move between satellitesand thelive feed skip outforjust over 45 mo . After the abbreviated hiccough , the ease of the fix run low reasonably much perfectly .

During operations , the Canadian Space Agency ’s Twitter feed pointed out just how remarkably flexile the Canadarm and Dextre are , teasing masses to try the contortions for themselves . The arm has 7 joints , while Dextre has an extra 15 , bestow together for astonishing flexibleness . Each of those joints can roll or bend , contribute in rotational or translational degrees of freedom .
The Canadarm deform to position Dextre to engrave its elbow with a twist .

Canadarm2is folded back on itself for#Dextreto reach the arm ’s cubital joint . adjudicate that with your branch . Then try scratching your elbow .
— Canadian Space Agency ( @csa_asc)May 23 , 2014
You did n’t just try that in your office cubicle , did you ? considerably explain to your stunned co - workers … .

In society to come up your own cubitus with the same hand , your human weapon system would need additional “ level of freedom ” ( or a pencil ! )
The Mobile Serving System has 11 cameras : two on the Canadarm elbow , one each on the Canadarm boom segment terminate , five on Dextre , and one at each mobile base place . yank the faulty camera out of position take unbolt it , then a fewcareful drag and the inevitable wiggle . The space ballet then continued with the Canadarm doing dip and pirouette to reposition Dextre to stick on the fuzzy - but - functional camera at the peregrine stand station . The installation of a new camera on the arm was completed the following daylight .

As well as rectify and replacing the worthful camera used in robotic operation , this is also the first validation - of - construct that repair - robot can service spacecraft while they ’re still in cranial orbit . While Dextre is an invaluable assistant for cosmonaut on the space station , perhaps one Clarence Day more robots like it will be sent to repair , refuel , and repositing orbiting planet . This would drop the cost of constantly replacing old satellites , and reduce theamount of blank space rubble we generate in orbit .

We live in a world with ego - repairing space robots . It ’s been a busy month for the robots , too ! Earlier , Dextre installed the high - definition video television camera and laser communications equipmentthat is generate us online access toa constant live feed of our satellite from outer space . Is it too before long to say , “ Welcome to the hereafter ” again ?
