Hello everyone this is Eddie the magic monk what I'm going to do now is show you how
to build a quick 5-minute robot with the Lego Mindstorms ev3 kits so that you can
get a robot up and running pretty quickly and basically all this robot
will do is be able to drive around sort of like a car so let's get your brick
and you can see here on the side of the brick we have a few holes on the side of
the brick now these holes can be filled with pegs now pegs are just things that
you can insert into the holes in order to connect beams together
alright so beams oops this is in the wrong spot so beams are either straight
or they can be angular beams right and they can be connected to the brick
through these pegs so I'm going to firstly use one of these little beams a
yellow beam and I'm gonna put a blue peg through it one of these longer pegs I'm
gonna put it through the yellow through the yellow beam and then actually I'm
gonna put two of them through the yellow beam and then I'm gonna put this through
this brick all right vertically on the right hand side and make sure you press
the press the pegs in and I'm gonna do it on the left-hand side as well might
as well do it now to get it out of the way
so get two of these pegs put it through the beams
put it through the yellow beam and then and peg it on the left-hand side of the
brick vertically downwards alright so the robot now looks like this okay so
the next thing we're going to do is get an angular beam an angular beam and it's
gonna be one of these ones with five holes vertical three holes horizontal
and we're going to put it attach it to the yellow beam like this so that we
have one hole sticking on top of it all right so it's like this and then we're
going to do on the other side as well so same beam on the other side with one
hole sticking on top so it looks like this alright so pretty easy so far so as
you can see with the blue peg it is pretty useful to use the blue peg when
you want to join three things together so we have three parts joined together the
brick the yellow beam and the white angular beam
alright so pegs are just used to join beams up and now what we're going to do
is we're going to connect a motor to these three holes on the side of the
brick alright so let's get a motor from the box right grab a motor and then what
we're gonna do is we're going to get three black pegs three black pegs and
we're gonna hook it up alright to the first in the last hole on the side of
the brick alright and then we're gonna join up the join up the
motor the large motor to these two pegs and just push it in all right so it's
now hooked up and let's do the same on this side
so put two of these two of these pegs onto the first and last hole
horizontally on the angular beam and then put get a motor and push it in push
it in okay so you can see here I have a robot with two motors on the sides now
you might feel that these motors are a little bit loose a little bit loose
it'll probably still work a little bit loose so I'm gonna connect them down
below so flip it over and then you'll see some holes on the back of the motors
right so now I'm gonna grab one of these longer beams longer straight beams and
I'm gonna put a gonna put a peg at the end on the ends of the beam so on the
left hand side put a peg through it right inside for the peg through it
alright and then I'm going to put it slot it on the bottom of the robot
behind the motors so slotted in here and here and just slot them in and sort
of hard cuz the camera is in the way
all right so it sort of helps me stabilize it a bit more so this is less
likely to move now okay so we want to now attach some wheels onto the robot
all right so for the front wheels we just grabbed them out of the black box
front wheels are basically you had to put the tyres on the wheel yourself so make
sure you do that so it originally came separately put the tyre on and then
you'll see throughout the through the middle of the wheel is a hole and you
actually put what we call an axle through it an axle is basically a stick
a very long stick right but the shape of it is in a form of a cross sort of
alright so get one of the grey ones that are about five centimetres in length
push it through push it through the push it through the the wheel and then what
we use what we call a bushing which are these grey thingies and put it one on
each side of the wheel put one on each side of the wheel to stabilize it a
little bit stabilize it all right and then you're going to stick this wheel
onto the actually make it a bit longer on one side a little bit longer on one
side and then you're gonna stick this wheel to the outside of your robot
throughout through the middle of the motor okay just push it in
all right so now the wheel is attached to the motor all right and push to push
the axle in okay so it goes like that you know you're gonna do the same for
that side grab the wheel push the axle through it push the axle through it
stabilize it with pushing
and then stick it on the outside of your motor so stick it through push the axle
in a bit more okay so you know you have a robot like this and if you put it on
the table okay if you just put it on the table
you'll feel you'll feel that something is missing all right because it's gonna
move like that but your brick is gonna be touching the floor so in order to fix
that what you're gonna do is you're going to use this piece here which is
actually a wheel right it's a metal ball that you can slot into this piece I'm
not sure what it's what it's called but it basically rows around the floor like
like a wheel alright so now we're gonna insert this insert two pegs into it
alright put two pegs through it and then we're going to insert this on the back
of the robot just in front either in front or behind doesn't really matter
actually maybe do it behind then behind this really long beam and just slot it
in all right slot it in so you have a wheel on the
back on the back and now you can drive this around so we'll show you how to
drive it around in the second but now it can move around on the table pretty
easily
okay thanks for watching guys uh see you next time.
