Wall-U

Description

movie props : Wall-E, starting by making it in cardboard and see where it leads us.
Creating an interactive Wall-E like robots that can move around while detecting when there is a wall in front of it. Wall-U should be able to move its arm and eyebrows in a first time.
Then might add shock sensor to make it cry if you kick it .

Details

What we need so far :

[ ] 2 DC gear Motors + L298N (wheels)
[ ] 2 servos 180 (2 arms)

[ ] ultrasound sensor
[ ] breadboard
[ ] arduino uno
[ ] power bank/cell/thing battery ( battery for motor AND arduino )

[ ] switch button
[ ] acceleromater
[ ] Infrared IR sensor
[ ] IR remote controller

Wall-U V1 :

wheels
arms moving
wood box
detects walls and avoid them
open its trap manually
raise its arm when kicked or shakes

Wall-U V2 :

- remote controlled

-ancy catterpillar tracks

- make sounds

Wall-UV? :

belly opening automatically
head moving
make it pretty
painted

Final touches and the arm !
Assembling the box and rewire
mariz92 • 05/29/2024 at 14:51 • 0 comments

Today we reassembled the box and rewired the circuit with the new components(sound)

the robot moves forward and senses when a wall i ahead while moving his “arms” (the servo motors for now only) and changing arm direction when titled.

We also found a smart way to fix the box body on the tracks without using nails,glue or screws!

We kinda sew it with a plastic string!
~1h later~
We implemented the remote controller device to control WallU !

Sound electronics
mariz92 • 05/02/2024 at 10:46 • 0 comments

We received the electronic part for the sound device and are trying to make the code work
+
we re made the box 20% smaller and laser cut it.

The electronic part working !
mariz92 • 04/11/2024 at 09:17 • 0 comments

Today we wired every electronic again with the new wheels and everythign works again !
we don’t have the new box yet though ….

Neat wiring & gyro code working !!
mariz92 • 03/14/2024 at 11:22 • 0 comments

Today we finished to modelise the wiring on EASYEDA and finally made the code for the gyro work as we wanted !
Merging code and parts
mariz92 • 01/12/2024 at 11:05 • 0 comments

Today we merged the code of each part toguther and also the physical part !

We started by putting the caterpillar tracks on the chassis and tested it with the motors.

We tried to make the wire cleaner

Biggest challenge was putting the arm in the box.

we finished improved the code.

AVENGERS ASSEMBLE DAY

it starts looking like something
caterpillar tracks
mariz92 • 01/12/2024 at 09:09 • 0 comments

Today we went to Leroy merlin To bug more screws !
We finally assembled our caterpillar tracks.

mariz92 • 01/12/2024 at 09:08 • 0 comments

Today we assembled the caterpillar ( they got bigger uhu) but we couldn’t finish to put them toguether because we didn’t have enough screws.

We put the wheels on the motor and made them work with the box.

And the arms we assembled as whole !

Caterpillar tracks and moving arms
mariz92 • 01/12/2024 at 09:04 • 0 comments

Today we assemble our firsts parts of caterpillar tracks and part of the wheels!
We also made the little trap door for the box and put the head on the top of it ( the proportion are off but let’s say it’s cute !)
We also have the mechanism of the arms working !

3D models

3D print the caterpillar tracks : we printed 40 pieces in total (20 for each side), 2 main wheels for the motors and 4 secondary wheels. We assembled the tracks using M4x25 screws and bolts.

3D print the arms and the mechanism that go with them. You will need one of each piece. ( more detail in the PDF concerning the arms in the files)

3D print the head and eyes. Place the ultrasonic sensor in the space and add the eyes.

You can find the models in STL in the file.

The box :

20X20X25 (inside)
Chassis : 3.5 cm high 20cm large fold plastic and screw on the bottom

Laser cut the body and assemble it. It should click into place thanks to the finger joints. Our wood wasn't perfectly flat so we had to use a few pieces of tape to keep everything together. We also put the SVG (laser cuttable) file to your disposal.

The code

Upload the code into an Arduino board (we used a Uno). Plug in the components. To plus everything, you can follow the image of the wiring we posted.
