Transcript

00:19
when you've come to the Canada aviation
00:21

00:23
pieces of history but there's one that
00:25
you cannot miss it looks it is it's
00:29
Aaron Gregory with the Canada aviation
00:30
and Space Museum hello Aaron so what are
00:33
we standing in front of we're standing
00:34
in front of the very first Canada arm
00:35
the very first Canada so we did this
00:38
bone to space it went into space for the
00:41
first time in 1981 right and retired in
00:44
2011 30 years and how many times does it
00:47
go into space it went to space 23 times
00:49
I travelled 153 million kilometers Wow
00:52
yeah can we touch it no why not it went
00:56
into space well of course but people you
00:59
know picking at it and tearing the
01:00
blankets and the wires you know we don't
01:02
have maintenance crews for that this is
01:05
basically handmade that's right yeah it
01:07
was built over the course of the 70s and
01:09
/ swing space in the early 80s and had a
01:12
very long illustrious career now how
01:14
many parts are there to the Canada
01:16
there's a few parts so the first part is
01:19
the shoulder shoulder you have the upper
01:21
boom right the elbow it really is an arm
01:23
it really is an arm lower boom yeah the
01:26
wrist joint yeah and the end effector so
01:29
which end is this this is the end
01:31
effector okay so the end effector
01:33
essentially the hand yes so on the face
01:36
of it you'll see a wire snare device
01:39
that's what it uses to grip so it lines
01:42
up with a special grapple fixture and
01:45
connects right and then grabs on so we
01:48
can do soft docking it can hold things
01:51
stationary it's actually quite dexterous
01:53
for for what it looks like cuz it
01:55
doesn't look like there's a neat doesn't
01:57
at all but that's the that's the design
01:58
of the grapple feature and when the
02:00
space shuttle Columbia blew up the role
02:03
of the cannon arm changed it's true
02:05
Columbia had some shuttle tile damage
02:07
and upon reentry that caused an
02:10
explosion and disintegration of the
02:11
shuttle and the loss of the entire crew
02:13
right this was a great tragedy obviously
02:15
that NASA wanted to avoid in any future
02:18
shuttle missions and basically either an
02:21
inspection boom was built to go on the
02:23
end of the canadarm2
02:25
extend its reach okay there was a camera
02:28
system put on the end of that inspection
02:30
boom that was developed by a company of
02:32
Canada called neptr yes a great company
02:35
yeah so laser laser camera system or LCS
02:38
and that basically took 3d scans surface
02:42
scans so the art without long enough
02:43
they could see yeah right under curl
02:45
right underneath and scan the whole
02:46
belly and any other hard-to-reach areas
02:49
that that other cameras couldn't
02:51
couldn't detect any damage and then what
02:53
would they do with the scans they would
02:55
send the information back to earth where
02:57
3d prints were created the 3d prints
03:00
were sent to NASA as well and the French
03:03
were made in Ottawa yeah and Sun to
03:06
Santa NASA and then NASA would examine
03:08
the damage and decide whether or not a
03:11
spacewalk was going to be required for
03:12
to repair the tile or if the damage you
03:15
know was it was deemed to be you know
03:17
not significant enough to prevent
03:19
re-entry or to cause you know cause any
03:21
other disasters on reentry
03:23
so other than the Canadarm what else is
03:24
there to see here well we have lots of
03:26
great staff at the Museum currently we
03:28
have Chris Hadfield Sokol suit on
03:30
display and we also have locals through
03:32
the SoCo seat so it's the only worn
03:34
space that's right to and from the space
03:36
station aboard the Soyuz cool and we
03:39
have the life and orbit exhibition if
03:41
