hello youtube this is Chen I got this
robot kit I ordered from banggood.com today
it's pretty cheap and looks like
some good stuff inside so let's take a look
okay nicely packaged
so it comes with Arduino Uno
equivalent I believe
this is is a servo for the Ultra Sonic Sensor
Screwdriver, USB for Arduino
this looks like a Arduino Sensor Shield must be for the ultra sonic sensor
Ultra Sonic sensor itself.
some hardware that suppose
to hold the sensor and you can use the servo to drive it around
This looks like a motor drive
Arduino Uno equivlent
so I guess that's all the drive wheels and the bodies  of the car
These are some gear motors
One board that holds everything
got a battery holder for 4 AA
Some loose wires must be the connection for the motors
Some little pieces I guess that's holding the motors in place
There's a third wheel
Rocker switch
4 of these
thess are some encoder parts that connect here and you can use a sensor to detect the angles they located
And bunch of  hardware
surprisingly it doesn't
come with a manual so not sure how to
put them together but I'll look it up
online and hopefully I'll find something
and share with you guys
hello guys I'm back after some research I
did find some tutorials online
they're mostly in Chinese so I guess
that's why it's so hard to search for
luckily I'm here so let's start building
it
so if you look closely with this board
the holes are not symmetrical so
there might be some reason for that
I don't know yet but uh you know maybe we
have to switch side later
so first of step you can peel off this films but you know to make it clearer to see on the
camera so I'll just leave them on let's
do the wheels first
so based on what I found online you want
this yellow dot right here that
facing outside so the way it works is
you put this two pin things across here
you put the wheels on
then find those long screws and two wholes here
Just stick it all the way to the other side
and use a nut to fix them
it's a
little tricky for the bottom one cause it's
like no clearance in there but it's doable
okay so you
could put the encoder wheel on
Or maybe it's easier for you if you want to
attach it before putting the motor on
so this two holes here I believe are used
for the encoder  optical sensor and put
the wheel on here okay so this one set done. Let's work on the other end
so this will be the bottom to the car
like sit like that and make sure that
yellow dot is on the outside
now we need to put this third wheel so I
guess you can put it flush just against
the board but it will be tilted a little bit
from what I read you need these standoffs
to extend it a little bit
We 'll just use these smaller screws
Okey, so now it's pretty flat
The 3 wheels are on the ground
and for this guy   s I don't know where
the best locations yet but this looks
like a pretty good fit for the rocker
switch probably want to mount it from the bottom
I don't know yet okay maybe we
can jump to this servo parts
based on the comment from this product or reviews lot of people don't know how to use these parts
and I did do some research and
figured out it's actually a pan and
tilt camera mounts which is kind of cool
if you want to put a camera on it
The kit only comes with 1 servo
So it's mainly for this ultra sonic sensor to move this way
So it can detect any obstacles
ah let's put them together so
the way he works is this little 2 parts go in this way
and look close there's just enough space to fit that
Make sure it's pretty tight
And put this part here
okay
misaligned, it's OK
all right for this part actually you can
put another servo on
I happened to have one with the same size here
So basically you mount it  the other way, mount it like this
2 screws down
there and then this pin goes in here
and the servo gear goes to here
Then you put one of the arms here to connect the part
So it could  move up and down
But for this build we really don't need this part
So after this, we can mount it like this here
To make it work we
need to use one of the  arms
Extra parts too - okay so we need a clipper
So we got the clipper now,  the goal is to cut a long arms short
so it  fits in there
I mean it's still pretty fat so let's trim this a little more
guy's I realize I made a mistake I clipped
this too much so uh doesn't fit anymore
I mean none of these little tiny holes fit
there for us to clip it on with the screw
but anyway I think it's gonna
cause other problem too in the end
because you know this head of the screw
gonna stick out so uh we'll just use
most powerful tool and favorite the hot glue gun
Looks pretty solid to me, alright
now we can put this on and it should
rotate like that
the last step we need to screw this on to this guy here but it's funny all the hot glues are stuck there
So we remove them really fast
Should be good now I mean we probably
should play with the angle in the
future so you know this location is
centered
okay so for that installed we can put the
ultra sonic on
based on the tutorials I saw they were using some of this this wire thing that usually you can find for cables
basically I just tie them up
you can use rubber bands I believe
here we go this is our head of the robot
and I found there are 4 holes at the front just here
These 2 and this slot that could fit it
like that
We got bag of screws for the pan and tilt head, we 'll just need the small piece
Forgot to mention we need to screw down at some point here
Which are this part so there are 2 screw holes
But it's pretty tight because the servo is in there, okay, just for extra security
Okay, now we'll just need to use these machine screws
Not sure that's long enough but we can take a look
It barely stick out, so potentially it could work
Alright, the next would be the battery holder, the arduino and the motor driver
For the sensor board it definitely it goes on top of the arduino.
Just look for the orientation like that
And this I didn't find the perfect hole setup yet but I can imagine we'll have this arduino port either point to the back
So you can have all the ports or have them on the side
These guys I don't know . I don't know where to put the battery holder
I mean you can put it on the bottom, it could fall off
plenty space down here we could route all the wires through this hole. Not a bad idea
So we can have the rocker switch, just push it in. Okay, looks nice
I mean I really dont want to put the battery holder on the bottom in case the batteries fall off
But I guess that's the only way cause this is gonna be too tall and you don't want expose all the electronics down there
I guess the final layout is totally up to you, something like this or this
And  from the resources I found all the boards come with stand offs just like this tiny guys
So the bottom of this PCB is not touching anything metal to create a short
This kit doesn't come with that, so you probably want to find something to insulate
That's all so far how we got
Alright, cool, I'll figure out all the connections then create another video
Thanks for wathcing!
