In this episode I'm gonna create a 3D printed robot using Tinkercad for the

design and the electronics. I'll show you it all right here at Filament Friday

Filament Friday is brought to you every week by the generous donations of my

patreon supporters. Support us at patreon and you get special access to CHEPClub.com.

I've been thinking about combining electronics and 3D printing and make an

autonomous robot. This one from parallax is used in a lot of schools so I thought

maybe I can make this educational so this inspired me to design my own. Here's

what I designed in Tinkercad I used various parts that I found throughout

Tinkercad and then put this together plus a lot of modifications. It's got

slots for servos on the sides the top holes for Arduino and a little ball

that goes on the front but here it is fully assembled so you can see what its

gonna look like. I found a lot of these pieces available in the free area of

Tinkercad. I got a servos on both sides I designed these custom wheels. I've got a

servo on top with a Sharp sensor that'll scan back and forth for obstacle

detection. I've got an Arduino R3 on top although I'd like to do my own custom

electronics. On the bottom I have the ball that I did find on Tinkercad and

it's just got a pin going through it so this can roll. I've also planned some

sensors that I can monitor the wheel these holes in a wheel. I designed this

wheel to go right by the sensor infrared detector so I can count pulses and

determine how far to go forward and back. This block here will represent sensors

and possibly a line follower on the bottom and then I've got some AA

battery designed in for the servos and a 9-volt battery compartment underneath

for electronics. So that's the overall plan but I'm gonna do something real

simple just get this thing driving to start. So here it is printed at a point

three layer height on my CR 10 mini. I did use supports and the holes for the

servos so I popped out those supports and this really came out quite nice

for a point three layer height I just used some PLA plastic. Then I installed

some standoffs that I just screwed in from the bottom into the holes for the

arduino and then I put a screw through the ball and just tightened this thing up.

I'm gonna have to list all these parts at some point but right now I'm just

kind of throwing it together. So then I use some metric screws to tighten up

these servos and they fit pretty nicely. Actually I got the dimensions just about

perfect. You got to angle the servo here and

these are parallax servos the same ones using that robot I really like them and

it pops in holds in place and then I just use a screw and nut at the four

locations and screwed it into the holes that I designed into the wall. The

Arduino pops over those posts that I put in place earlier just slides on and then

there's two nuts that I put at the back of this thing and there's plenty of room

for those nuts but the front two there's not enough room for nuts so one of them

I had to flip over and put a nut on the bottom so it had to screw in from the

top so I just put a screw and that fit into this board the other hole was

basically hopeless so it just stayed as a locating post so I got three in place

that should be good for power instead of a 9-volt battery I used this 9-volt

battery shield that I created and this was a Kickstarter many years ago that I

did, successful Kickstarter. And that'll power the electronics then I have this

DF robot screw shield that has some terminals for servos so I plugged in the

left and right servos into pin 9 and 10 and power for the servos comes from

four AA batteries now the connector wouldn't fit in a little hole I'm gonna

have to make that bigger so I just shoved it through the top servo which

I'm not going to use right away and then I just used some double-sided sticky

tape to hold this in place so I just put it in place and squished it down so

there's no 9 volt battery because that's a shield but I want separate power from

the motors and the electronics. Now these wheels are not the 3D printed design

wheels these are ones that I had I want to just get this thing working first so

I want to get some code running so I just used these for now and then the

last step is just connect power from the four AA batteries into the shield

for the servos. So that's the assembly it's done and this is actually the front

of it so I need to do more work down the road and make that look prettier but now

it's time to do the code. So I go back to Tinkercad circuits and here's the servo

bot design that I made it's got two servos and an Uno connected to nine and

ten here like you see and then power and ground. That's the full circuit. Now I

like to code in actually text mode not the block mode I just find this is much

easier for me so I included the servo library with the servo dot H. I made a

couple variables defined the two left and right

servo names and I'm the connections to pin nine and ten. Then I made a series of

functions one that stops the robot and by doing that if you send a fifteen

hundred millisecond pulse or 1.5 millisecond, fifteen hundred microseconds

to both of them they they stall because these are continuous rotation. A thirteen

hundred drives it one way a seventeen hundred drives the other way so that's

how I do it forward and reverse then I do two 17s for a right and two 13s for a

left and I control how long it is by this variable move. So in the main

program all I have to do is call those functions so I'm gonna call stop here

with a thousand and thousand gets put in to move and it's gonna stop for one

second basically, and then it's gonna go forward for two seconds left for seven

hundred milliseconds forward for two seconds and just goes back and forth and

this is gonna draw a square or drive in a square and then it's gonna do it again

but everything in Reverse. The Tinkercad circuits lets you simulate the operation

which is really cool but now these aren't continuous rotation servos these

are standard servos so when they're flat to each other that's when it stopped and

then when they're both turning in opposite directions that means it's

going forward a reverse when to go on in the same direction then that means

they're turning. So that's how I can tell that my code is working. Now the next

step I could do is run it in debug mode which is another feature in Tinkercad

now I can set a breakpoint here with these little blocks so it's gonna stop

at each of those lines and let me control it. So it's gonna stop you can

see they're both in line and the robot I'm gonna show you how the robot should

operate it's stopped and then it runs the forward command and it does that and then

it does a left turn and I'm clicking the arrow over

here to continue so I'm just stepping through the program and then I'm showing

you what the robot should do based on these commands. So it's drawing the box

and then turning and driving and turning and driving so it's completed the box

now it's gonna stop for a second and then it's gonna go and reverse. So it

goes reverse and then it's gonna turn right and then it's gonna go reverse for

two seconds and then it's gonna turn right and and then do that until it gets back

to where it started hopefully. And here it goes to the final movement and it

drives back to where it started. Now you can see it's not exactly where it

started and the turns weren't perfect but it's close enough for this so I'm

gonna copy and paste this into the actual Arduino IDE so I can program the

robot and see if this will do exactly what I want it to do so I plugged in the

cable from the computer into the Arduino and click upload and it uploaded the

code and here it is in full motion driving itself just like I showed in the

debug but basically this is at full speed here and then it does reverse and

comes back so what I want to do now is improve its accuracy of its turns and

its movement so the next step in this robot is to get the sensor working the

infrared detector here that actually shines through these holes that are in

the wheels I designed. And so I've got to improve the wheel a little bit that you

can see if I make this a hole, let me make it into a hole here, you can see

that the sensor the center of the sensor lines right up with these holes so I can

count pulses by counting when there's a hole or no hole and determine how much

to turn or how much to go straight so this should make the robot a lot more

accurate. This is a work in progress so I'm not ready to release anything

although I am sharing all the files with the bronze, silver and gold members of

CHEPCLUB.com so they can build along with me give me some feedback. So if you

want to do that join us at CHEPCLUB. And the winner from the last video for the

Teenage Boy Has Laid 20 Eggs Leaving Doctors Baffled - Duration: 6:18.

Teenage Boy has laid 20 eggs out of his bum.

Perfect timing I suppose with Easter right around the corner.

Yeah I make awkward jokes when im uncomfortable.

So 14 year old Akmal claims to have laid 20 eggs over the past 2 years and doctors have

no idea why this is happening.

Hes been in and out of hospitals trying to figure out how and why this is happening.

Originally doctors took this as a practical joke- as...you now… its impossible for a

person to lay eggs.

They thought the teenager was shoving the eggs up his rectum just to get a reaction

from people.

But one time he even laid 2 eggs when he was at the doctors office.

Eggs that hes laid have been cracked open and they are revealed to be all yoke or all

white.

About this the teens dad said- hes been x-rayed and doctors found an egg in his bum.

In 2 years hes laid 18 eggs and 2 today- so in total there have been 20.

I cracked the first egg and its content was all yellow no white.

A month later I cracked another one and its content was all white and no yellow.

Doctors don't know what else to do so they have decided to quarantine the teen for a

week while they try and figure this out.

A spokes person at the hospital said- Our suspicion is that the eggs were deliberately

shoved up his rectum- but we did not see it directly.

Scientifically chicken eggs cannot form inside the human body- its impossible- especially

in the digestive system.

They are going to find out once and for all if the eggs come naturally from inside Akmal.

Which im going to take a big leap here and assume they dont.

Hey guys welcome back to Lp im court McGinley.

TGIF its finally Friday.

Let me know what you have planned for this amazing weekend down in the comments.

Also I just want to let you guys know that this upcoming week Landon and I are not going

to be here- were going to be on a cruise- which im super excited for- but I am going

to miss you guys.

Make sure youre following me on instagram at court mcginley so you guys can stay up

to date with what were getting up to.

But don't worry im leaving you in good hands.

A friend of mine who some of you might recognize will be taking over hosting this channel for

the week.

Do you have any guesses who it is?

Let me know below.

And stay tuned for tomorrows video as I will be introducing him to you all.

Alright as you guys know we have a lot of interesting news stories headed your way so

without further a due lets get started.

--Next- a fitness model has been paralyzed from the neck down after doing sit ups.

This is 23 year old Marcelle Mancuso.

She actually broke her vertebrae after she slipped off a bench while she was doing inverted

sit ups.

She was rushed to the hospital where doctors operated on her and they fitted a titanium

plate held by 6 screws into her spine.

About this Marcelle said- I went to perform the abdominal inverted sit up and was upside

down.

I was attached to the equipment with a strip- which broke and the personal trainer could

not hold me.

I hit the back of my head on the floor and immediately lost all body movements with the

blow.

The doctors didn't know if I would walk again.

I gave my best every day in physical therapy and gradually my movement is coming back.

I couldn't even imagine how terrifying that would be.

Youre just in the gym working out- you fall and then cant feel or control your body.

That must have been so scary.

But luckily she is on her way to a full recovery.

--Next- Team USA wins first Olympic womens hockey gold in 20 years.

Its being said that the United States womens national hockey team is without a doubt the

best hockey team in the world.

Team US and Team Canada played this final game to the bitter end.

The game went into overtime and then a shootout where Jocelyn Davidson scored the gold medal

shot in the sixth round.

Congrats to Team USA on this well-deserved win.

--Next- Police investigate white powder sent to Meghan Markle.

Its now being reported that back on February 12th a letter was delivered to St. James Palace-

it was addressed to Meghan.

It contained white powder and a racist message.

Originally there was concern the letter contained anthrax- which is an infectious disease.

But soon after the substance was determined non- suspicious.

Obviously the letter was intercepted before reaching the couple but they were made aware

of the situation.

All these people in powerful positions seem to be getting these letters filled with this

non-suspicious white powder.

The police have been investigating this issue but so far have no leads.

This is pretty scary as the royal wedding is now less than 3 months away.

But the wedding is sure to have high security and Meghan has been trained in how to deal

with threats and kidnappers.

But hopefully she will never have to put that knowledge into action.

--Next- Marvels Moon girl and Devil Dinosaur comic is being developed into an Animated

series at Disney Channels Worldwide.

As of now the animated series is being worked on but it doesn't yet have a set network.

So I guess they are waiting to see how it turns out before they pair it with either

Disney channel- Disney XD or Disney Junior.

The comic launched back in 2015 and threw it we follow Lunella a 9 year old genius-

along with her prehistoric friend Devil Dinosaur.

As one of the smartest people in the Marvel universe Lunella loves to create inventions-

even though they tend to get her into trouble.

But Lunella is also more than just a genius- shes inhuman- with the ability to swap bodies

with her gigantic crimson dinosaur pal.

This series does not yet have an expected release date but it sounds pretty cool.

--And its that time of the week where I let you know what super cool awesome movies are

hitting the box office this weekend and we have: Game Night and Annihilation.

Alright lets start off with game night this movie is rated 14a and it's a comedy.

In this movie youll see- Jeffrey Wright- Jason Bateman- Rachel McAdams- Kyle Chandler and

Sharon Horgan among others.

And fun fact Jonathan Goldstein and John Francis Daley Both co- wrote and co-directed this

movie.

In this movie Max and Annies weekly couples game night gets kicked up a notch when Max's

brother Brooks arranges a murder mystery party- complete with fake thugs and fake federal

agents.

So when Brooks gets kidnapped its all a part of the game right?

But as the 6 uber competitive gamers set out to solve the case and win they begin to discover

that its actually not a game at all.

Over the course of one chaotic night the friends find themselves increasingly in over their

heads as each twist leads to another unexpected turn.

Take a look Next we have- Annihilation.

This movie is rated 14a and it's a Sci-fi- suspense movie.

Alex Garland both Wrote and directed this movie.

This film has an intimate cast including- Natalie Portman- Jennifer Jason Leigh – Tessa

Thompson- Oscar Isaac and Gina Rodriguez among others.

This movie is based off of Jeff VanderMeers best-selling trilogy Annihilation.

In this movie we follow 4 women into an area known as Area X. the area is abandoned and

cut off from the rest of civilization.

They are the 12th expedition.

The other expeditions have been taken down by disappearances- suicides- aggressive cancers-

and mental trauma.

Heres a sneak peek And there you guys have it that's all the

stories I have for you today.
