this is sophie she's gonna make me a
training droid to help enhance my jedi
training
all right let's try this again
[Music]
this video is sponsored by kiwico the
future of play is engaging enriching and
seriously fun
it's one thing to build a lightsaber but
wielding a lightsaber is entirely
different
jedi go through years and years of
training traditionally starting as
younglings progressing to padawans
before ascending to jedi knight
and you know maybe someday being granted
the title of the master
hello there but hey we all know luke
didn't start as a young one
and he only saved the galaxy
so i think it's fine to start at a more
advanced age of
30. speaking of padawans here at
hacksmith industries we take on
co-ops from a variety of tech
backgrounds and experiences to help them
refine their practical hands-on skills
and because projects take months and
months to complete we need a team of
engineers to manage to come out with a
new video week after week after week
this is sophie from the university of
waterloo she studies mechanical
engineering and
according to this she's also a member of
the waterloo rockefeller team
she clearly knows a lot about sci-fi
tech hired
she'll be with us for the next four
months and in those four months she's
gonna make me a training droid to help
enhance my jedi training
and by the next four months i actually
mean the previous four months because in
typical hacksmith fashion we're actually
filming the intro of this video at the
end of the project
anyway i guess i better get started
training
to build our training droid the first
thing we're going to need is a camera
that can recognize and more importantly
track people
fortunately for us this camera already
exists it's called the zed
ii made by stereo labs this camera is
the full package
it's built for the spatial ai arrow with
its big power and small form factor
but how exactly are we going to make
this camera fly
i could just use the force but
that isn't always exactly shall we say
practical
so we're going to rely on drone
technology
no not droid jerome i spent the better
part of a month researching the
components that go into building a
custom drone
and settled on these first we found the
receiver
the freesky x8r it uses the sbus
communication protocol to take
instructions from the remote control
we want to make this drone as powerful
as possible so we got this three
thousand milliamp hour 6l lipo battery
to power the entire thing
next up we have the t-motor f4 flight
controller this is the brains of the
drone the leia organa of the operation
it takes the instructions from the
receiver and tells the motors what they
need to do
paired with the flight controller is the
t-motor 55 amp pro 2
electronic speed controller esc for
short
it takes in the instructions from the
flight controller and gives the motors a
certain amount of current so that they
spin
next we have a question of optimization
those who know drones know that there
are balancing act between rotational
speed and power
you need both of those to push the air
down and create thrust we chose the
t-motorvillox 2208 kv-1750
motors and the t-motor 5147 propellers
that's a lot of numbers that have
specific meanings but i don't have time
to explain that to you right now
together these generate 6 800 grams of
thrust they're the perfect duo
like han solo and luke skywalker
blasting tie fighters out of the sky
all of these components get strapped to
a frame this is just a prototype
so we laser cut two layers of wood with
lots of holes for the flight controller
stack
the battery the receiver and the motors
and finally
the remote controlling business comes in
with the transmitter the freesky taranis
it's got all the buttons and switches
i'll need to control the drone
let's assemble this thing and make sure
it works
[Music]
flows from the force but beware of the
dark side
okay let's see if this thing can fly i
assume you it will
[Music]
so
people are constantly asking us how we
got started in engineering which is why
we're thrilled to partner with kiwico
so thrilled that we're giving our
viewers 50 off their first monthly crate
sometimes when you're small it's easier
to think big but kiwi co creates
hands-on projects
and toys designed to expose kids to
concepts in steam
science technology engineering art and
math they believe that the small lessons
today
can mean big world-changing ideas
tomorrow each monthly crate comes with
all the supplies needed
detailed kid-friendly instructions plus
an educational magazine for further
learning
with eight subscription lines each
catering to a different age group and
skill set
there's something for everyone i may not
have kids myself but after completing a
few of these kits i can't think of a
better
way to get kids interested in making
things check out kiwico.com

description below
plus you'll be helping to support our
channel what about guns
the droid needs to fire something at the
person training
unfortunately lasers like in the movie
don't exist in real life
but nerf does and we have like 400 nerf
bullets left over from the screaming gun
project
to fire these little guys i'll have to
design a custom launching mechanism
solidworks solidworks
this is the mechanism i designed i'll
show you how it works
it starts with two 3d printed parts
inside of that
are two motors that spin together and
launch the ball through
we've got a gating system to control the
firing rate and it moves in that way
controlled by the servo motor here i'm
happy with this design
let's print it
our 3d prints have finished so we can
start to build the launching mechanism
we've got a pipe here to act as the
magazine it'll hold about 10 nerf
bullets
we've got motors to launch them some
other pieces for a gating mechanism
a servo motor tons of nuts and bolts to
piece it all together
and my trusty glue gun pew pew
[Music]
uh
[Music]
so
so we have our camera our drone and our
gun problem is
they're stupid they don't play nicely
together so we need them to get together
and sing kumbaya to do that we'll write
some code
the computer needs to talk to the camera
the computer needs to talk to the gun
the computer needs to talk to the drone
and i need to talk to my mom
and you should talk to yours she misses
you
i've spent literally three months
working on this code
[Music]
it's the coolest and most infuriating
part of this project this is the most
complicated software that we've ever
written hacksmith industries
even more complicated than the software
that runs bogden
what ah never mind
we wrote the code and run the code on
the nvidia jetson
the jetson xavier nx is a powerful
little computer
it has 6 cpu cores and 8 gigabytes of
ram
it's designed to run computer vision and
machine learning algorithms
the camera plugs into the jetson
and the gun plugs into blast
the camera plugs in easily via usb but
the gun
flight controller and receiver all need
something different they're trying to
talk to each other but they're just
speaking different languages
if only we had c-3po to act as
interpreter how did we get into this
mess
it's time to hop into all team designer
and make our own 3po a pcb
all team designer is the industry
standard for pcb design
you can download it and try it for free
at www www.altium.com
yt the hacksmith there's also altium
viewer
a free online platform that allows
people to view all kinds of file formats
c3po has arrived it connects onto the
output pins of the nvidia jetson
and connects all of our hardware finally
they're all speaking the same language
that the jetson can understand
check out the full electronic schematic
on maker.io
[Music]
on paper everything should work but
let's put it to the test
we've got the camera and the gun hooked
up to the jetson
we've got a monitor connected to the
camera so we can watch the live output
when the camera recognizes a person the
jetson should tell the gun to fire
let's see if it works
okay all we need now is a person to
shoot at
i guess i'm a person
[Music]
oh my gosh it works okay this is awesome
oh my goodness
[Music]
okay now that we know everything works
we can move on to the final assembly
this will include a new frame with
mounting points for all of the hardware
we'll attach everything to that
[Music]
all right it's time to put this thing to
the test i just have to find a way to
lure james here
he's been training pretty hard i bet
he's pretty thirsty
[Music]
water
packs without store that's weird
[Music]
[Applause]
[Music]
all right this is pretty fun but we
didn't make the world's first plasma
based lightsaber
not to use it
[Music]
all right let's try this again
[Applause]
[Music]
all right that's not actually working
very well that's because despite this
plasma lightsaber being super hot
because the nerf balls are flying so
fast they don't actually have enough
time
to melt when they're flying through the
blade luckily we also have our tungsten
titanium lightsaber which has a solid
[Music]
blade
[Music]
three
[Music]
all right my jedi training has paid off
that was freaking
awesome the tungsten titanium solid
blade definitely works
alright this is freaking awesome our
very own star wars training drone
who doesn't want a drone that can target
you and shoot you
to help you become a jedi i think it's
freaking awesome he did a fantastic job
sophie and i just wanted to present you
