Meet Ewa



This is my 16th robot project EWA. Built from a Walle Ucommand toy. It has a 3d printed head from Xlrobots. I added a cooling fan to the front for a more industrial look. He has led mouth that uses a sound mic.Used hd servos for the head and neck. Micro servos for the arms and continuos hd servos for the tracks.Uses EZB V3 as controller .Installed 5000 mAh li-ion battery pack. Has carry handle attached to his back. Left the original sound board for sound effects. The concept is that if Walle and Eve had an offspring this what he would look like..Makes great little companion in my workshop. User-inserted image

Upgrade to ARC Pro

With ARC Pro, your robot is not just a machine; it's your creative partner in the journey of technological exploration.


wallE has finally a friend and good looking it.


It's just beautiful, it's really child looking. I lyke it. Felicitations!

I had to laugh looking at your pictures. He is sooo cute. I really do like what you have done with this little guy. Another Pixar movie star in the making for sure. Maybe he could audition for a Wall-E sequel, or even his own movie.

Seriously though, I love this little guy. Great job. :D


Wow, That's really cool! I like the look. You do great work, I'm impressed. It's funny, I'm actually working on a different version of Wall-e that I'll be introducing in the near future. Keep up the great work. You inspire me to keep moving forward. :)


Project showcases on this forum is what keeps me creating more robots.. I vote EWA as the cutest robot of the year !..I would like to see even more projects posted on this forum....Thank you all for the positive and encouraging feedback. PS.. And their is more come.


Yep. My vote for the cutest robot also.

Great job mate!

Do his hands and arms move also? If so, it appears they could reach the floor to pick things up?



any chance for a video ?


I have not posted a video yet because i have used my data allowance for the month .I will when it resets. Only the arms move with servos,not the hands.


Hi, it's Beth from that store in the mall. Just wanted to THANK YOU for your help in Miami Florida. I haven't gotten the problem resolved yet but I look forward to getting this project up and running. I did ask about the battery when connecting it and sure enough you were right. It was charged as it was put together. Again, Thank you for taking time out from your vacation to help


Great Job! It is the cutest robot. :-)


Excellent job! Looks great!



I'm looking for candidate 'bot heads to serve as user (student) interfaces with my remedial math tutorial system. It looks like Alan's availability will depend on the Indiegogo results and would not likely to occur until February or thereabouts. The EWA head might work well as an interface for middle school or even high school students . . . so this is your own design, right?

I would need a design that supports these minimal requirements:

SPECS: EZ-B v4 based Must support devices needed for Face recognition (digital camera), Voice recognition (microphone), Handwriting recognition (digital camera), Voice synthesization (speaker) Neck must have two degrees of freedom

Except for v4, does that match up with what you have done with EWA?

If so, in a few weeks, I'd like to talk about purchasing a head so that I can evaluate its fit with my project. Right now, I'm using a JD head for prototyping but am not sure that it will be the "go to" head for the final project.



Also, can you tell me something about the servos you are using?

Excellent job, nice robot. I hope the video will show us behaviour of ewa. :-) I am looking forward.


I use metal bearing hd servos for the head tilt and rotation..There are 2 micro servos for the arms and two continiuos rotation hd servos for the tracks.Since it has a Ezb v3 I use bluetooth audio and the original 2.4 ghz wireless camera.Can easily be used with Ezb 4. I just didnt have another Ezb 4 at the time of this build. Power is (2) 5000mah batteries at 3.7 volts each in series.


The head shell was 3 d printed from and customized led and eye lenses added.


rb550f, Great job on Ewa. I think it looks cool.

Mathprof, As far as a head design, I think it would be great to be able to show the math functions on the face of the robot, which would contain a tablet used to drive your robot. It would allow everything to be self contained and would allow you to just drop a head on a desk, plug it in and go. It is like the head used on my project. If you would like to know about this, please email me and I would be happy to send you some more information. My email is in my profile.
