In this video, I showcase a palm-sized WALL-E robot that is controlled by an Arduino microcontroller and 3D printed parts. I demonstrate how this adorable little robot moves and interacts with its environment, thanks to its fully functional arms and tracks. I'll take you through the process of designing and printing the parts, programming the Arduino, and assembling the robot.

to all makers you have to get the PCB in fact without it's not possible to put all inclusive :) I had to sacrafice the open door drawer to put all the connections !

@charlesrainesmusic4783 11 месяцев назад

This is awesome! Is there a way I could scale up the 3D design to support a larger compartment? I really wouldn’t mind having a little more space for my pico, motor driver, etc… I am brand new to 3D printing, so any advice is good advice..

@professorboots 11 месяцев назад

Thank you! And yes definitely, any CAD program you’re able to get your hands on should have the ability to scale the parts. A really easy to use one that’s great for somebody just getting into it would be TinkerCad or if you’re looking for something with a little bit more use and ability to grow with you id check out fusion360

I know you haven't asked on here, but I thought it would be better as it's not construction machinery.. have you thought of creating johnny 5 from short circuit.. I'm in the process of printing the skidi, and hoping I can learn to build a hk tank from terminator..

@colinjervis4661 Год назад

Just a couple of questions....do you have a link for the JST connectors that you used? and the second is, I have had the PCB made from the gerber files on your github page, but the pcb's dont have the switch connector holes (the ones near the bluetooth holes) where do I connect the switch to? Apart from the this is a great little project, I have printed all the parts got most of the electronics ready (apart from the switch, and trying to find a battery for it (the ones in the link aren't available atm)) and cant wait to put him together

@professorboots Год назад

Hello! I do have the link I can fetch it for you this evening once I’m back home. Also I’ll have to double check but those gerber files must have the original PCB files which didn’t have those holes. I spliced directly into the battery wire. It’s actually saves quite a bit of room doing it that way but adds the splicing step. still I’m so sorry for the confusion I’ll update those tonight.

@professorboots Год назад

I’ll also look into the battery situation. Thank you for bringing these to my attention!

@professorboots Год назад

Alright first things first here's the link to the JST connectors www.ebay.com/itm/363529978152?var=632753499838. I fixed the GitHub Gerber file for the PCB's though it sounds like its already to late as you've ordered them. As long as you're comfortable splicing the battery wire into a switch you will be good as thats the only change. Though if not let me know and we can figure something out. Finally I checked the links for the batteries, I'm in the US which says they're available I cant speak for area's outside the US though. I hope this helps, also I just set up a discord server about 2 minutes ago haha where people can ask questions and share progress. Here's the link discord.gg/eDNTa6qF

@hemanthraja171 10 месяцев назад

Yep , facing the same issue. But adding the switch to battery wires seems to be the way to go.

In which app are u controlling the wall-e in bluetooth mode

@jneo_misc7378 10 месяцев назад

Hi, thats amazing. Could i use a hc-05 bluetooth module instead of hm-10?

@professorboots 10 месяцев назад

I believe so though you would have to swap to a different app as I don’t think dabble supports the 05

@PhilipZollweg Год назад

I'm printing this and I noticed that the left leg is a different version? the slots to attach to the cross bar are too close together, and the posts are too short for the wheels to fit on. Also, what size bolt or screw did you use for the undercarriage assembly?

Hey sorry I saw your comment on thingiverse where I responded. I’ll make sure to update the file and get you a screw length measurement tonight. They are m2’s

@ryanruditz Год назад

This is great! what make his arms wiggle in the code? is that just part of that servo?

@professorboots Год назад

Haha this is a great question and something I spent so long trying to fix, it’s mainly the servos. After trying massive capacitors to maybe smooth out the voltage it mainly just came down to the potentiometer inside the servo not being super reliable. Even with the disconnection of the output signal from the arduino nano they still shake for a second after they are told to move. I finally chalked it up as a personality trait for wall-e. He’s just had one to many Twinkie’s haha.

@ryanruditz Год назад

@professorboots Lmao.. I I really thought it was a feature, not a bug. The shaking creates a cute, excited robot feel. I'm using different servos, and it they don't shake. I kept looking through the code, looking for something. Now I need to find a way to code it in lol

@professorboots Год назад

@Mrhufnagl 11 месяцев назад

the red LED... it's one with a built-in resistor, right? bc otherwise the LED will be dead soon, right?

@professorboots 11 месяцев назад

Great question! Originally I had a 150OHM resistor hooked up to prevent possible burn outs. Though room got pretty tight pretty quick so I ditched it. but after having run wall-e for literal dozens of hours haha without the resistor on the led I haven’t had issues. I credit this mainly to the fact that it’s not constantly turned on, but rather in short bursts.

@TinyHardware Год назад

Absolutely amazing build, I'm printing mine right now. However can I recommend changes moving forward on your videos.. "now just go ahead" you say it so much I was thinking about making it a drinking game. I mean no ill will on this just not sure if you know it's almost your catch phrase now :).

Haha, you are so correct in saying this! It’s definitely a crutch, I promise to try and say it less in my next couple videos. Also hope your wall-e turns out good!

Just to verify the app you tried was called dabble correct?

@professorboots Год назад

You might be able to use the arduino Bluetooth controller app instead. You will have to construct your own buttons and what not but it looks fairly user friendly.

would you ever consider selling a plug and play version of this?

I would love to but I’d hate to get in trouble for merchandising a Disney character since I don’t own the rights. I will be designing my own little deskbot, that’ll you be able to get in a plug and play kit. It’ll be a lot easier to assemble but still cool!
