this episode of holy sh is going to be a little unusual because I don't have
0:04
anything nope we had a special guest this is Michael S and he has brought
0:09
with him the HMC Galahad a 3D
0:13
printed the kinetic sculpture robot
0:17
whatever you want to call it that if you factor in his labor at even a mere 20
0:20
bucks an hour is worth over
0:24
7,000 us
0:35
tunnel bear is the easy to ouse VPN service that lets you use the web as
0:39
though you are in one of 20 different countries learn more and try tunnel bear
0:44
for free at the link in the video
0:52
description let's start with a breakdown of that cost because to print something
0:58
to this degree of quality and at this size would require a 3D printer costing
1:03
about A4 million about $3,000 of that
1:07
cost of the machine went to shapeways there's about another $200 in the cost
1:11
of the electronics that run the whole thing including the 18 freaking servos
1:17
not to mention the vibration Motors and all of that stuff and then by my rough
1:22
napkin math about $4,000 of it is in the
1:26
detailing which we'll get into in a little bit more detail later in terms of
1:30
other key specs the HMC Galahad has six
1:34
legs six genuinely moving legs by the way including access hatches doors and
1:39
Windows all of which open it's got 24
1:43
guns along the bottom half of its egg
1:46
likee structure most of which are anti-personnel type weapons then it has
1:51
an additional nine guns in the top half
1:54
including two very very large cannons it
1:58
has search lights in the top that actually move and are also capable of
2:02
being shuttered just in case you know you don't want them to get shot out by
2:06
an attacker or whatever the case may be and it includes even amazingly cool
2:11
little details like check this out there's a service staircase or an access
2:16
staircase for someone to get up into the top rotating turret which I guess leads
2:21
us pretty well into a tour of some of the other Immaculate details that went
2:26
into the creation of this I'm afraid to call it a product Cuz Mr Sing has only
2:30
created two of them so far the main gun here which actually fires by the way is
2:36
rifled on the inside of the barrel if you come around to the back you can see
2:40
we've actually got some soldiers that are that are that are Manning the uh the
2:45
HMS Galahad here when the engine smoke
2:48
goes there's actually some lighting back here it's got a 7.4v 3700 milliamp
2:54
battery that is enough to run it for a while but it doesn't deliver enough
3:00
current to run everything concurrently so all the switches back here allow you
3:04
to run certain things but not others because this is more of a demo than
3:10
anything else moving around over to this side check this out just these little
3:14
things are so cute these are accupuncture needles right here that are
3:18
acting as a little antenna here and of course I've been glossing over the
3:23
Fantastic weathered warn rusted paint
3:28
job that's going on here that accounted for something to the tune of 180 to 2
3:34
200 hours of the construction time the actual assembly only took a couple of
3:39
days function number one we're going to put the Galahad into what I'm going to
3:44
call Sentry
3:48
mode there we go and what you're going to see is the top turret is going to
3:53
start to slowly rotate looking for a
3:57
Target when it sees a Target
4:00
look at that it fires next up we've got most of the rest
4:06
of the guns so most of the ones along
4:09
the bottom are on vibration Motors so they look like they got that firing
4:13
action but some of them actually have a a similar firing in Bank sort of
4:19
mechanism going on the gatlings on the left rotate realistically and the right
4:24
ARM gun this one's cool this one actually has a recoil action that
4:29
includes the legs moving as well demo
4:32
number three yes my friends it walks although I don't know if uh walk is as
4:37
appropriate a term as Lumber would be
4:41
look at the way look at the way it moves the whole thing shifts around very
4:46
cool which leads us to the big finish
4:49
which as you guys always know involves the uh biggest gun and the largest load
4:54
this well it's a pingpong ball but it looks like a cannonball right here and
5:01
fire oh there it
5:04
goes okay the angles need to be tweaked a little bit we get that but uh there
5:09
you have it folks this is the HMS
5:12
Galahad by far the coolest and most
5:15
expensive robot toy kinetic sculpture
5:18
