Yet Another Wall-e

So I built my Wall-E months ago after receving it the day after I finished Metal Box-Bot, but I haven't got around to uploading my project until now.

While I was happy to receive what I thought was the U-Command Wall-E, mine seems to be a different model as it's much smaller than many I see on the forum including DJ's "Real Wall-E". I figured "oh well. Nothing I can do about it now".

While I did run into a few snags with the size I was able to build what I think is a pretty successful Wall-E. Especially since I had to meet my wife's deal of:

"I'll get you an EZ-Robot kit for your birthday ONLY if the first bot you build is a Wall-E. He's cute!".

So here he is:

Who need's cheap plastic gears? Not this guy! But I'll hold onto them in case:)

Careful cutting. Gotta make those continuous servos fit and hide.

User-inserted image

That should do it. Just enough left to hide the servos from the front.

User-inserted image

Servos in place.

Servo attached to the drive wheel. I hope it's centred!

Eye looks a little too small, but I'm determined to make it fit!

User-inserted image

Crooked, but it will have to do. Can anyone spot the mistake in this picture? Yup! The camera is upside down. I dind't notice of course until he was nearly put back together. Thankfully that wasn't hard to fix!

Webcam eye is now installed. Right side up that is... Oi.

User-inserted image

Cut out the arms to fit the servos.

User-inserted image

Install the head servo. thankfully with screws. I try to use screws where possible. Screws > Glue

User-inserted image

Arm servos installed using screws as well. Body assembled and battery pack tucked inside. Unfortunately some disassembly is required to replace batteries, but I'm okay with that. I'm just glad is fit into that little chasis!

A closeup of the snug fit inside. No room for the EZ-B, but I was able to attach it to the bak using a single pre-installed screw and hole. It swivels nicely in order to tuck all the wires inside.

And there we have it! His arm fell off just prior to this picture and I realize now that I don't have anything showing the attachment of the arms but it's exactly the same as DJ's Wall-E.

I will post a couple more pictures showing the profile of Wall-E all together when I get a chance.

So everything was able to fit. I have horizontal rotation for the head, but no vertical. If I do decide to install vertical, I will need to use a mini servo. I just don't know how much room I'll have with that tiny head.

Also I do have one problem. The left track is WAY stiffer than the right. So the rubber doesn't roll around the wheels properly. Up until HiFive was released, my Wall-E had a severe circle walking problem. With servo speed control I was able to slow down the right track, but man is he slow now. It's really too bad as he turned out really nice otherwise.

I'll post in the general discussion to see if anyone has any spare tracks for my size Wall-E. I have a couple pics of his measurements I'll upload if I have a chance.

So all in all THANK YOU DJ for this great experience. Once I have my Wall-E and his personality perfected, I plan to move onto bigger and better. And thank you to the community for the helpful hints and tricks.

I wonder if these would work ? Probably not but may be worth looking at tracks

#27  

looks like they would work real good,pololu has a lot of good stuff takes awhile to get to usa robotshop canada also carries pololu tracks too ,hwtech canada does also might be a place in the UK that carries pololu too

How would I use those? Replace the whole underbody with this? or try to shorten and then wrap these around the Wall-E wheel assembly?

I don't see them fitting the current wheel assembly. I'm thinking I might just either start over with a new actual "U-Command" Wall-E or build a different bot. I realized, I wouldn't even have room for a sound board.

And I'm weary about using a bluetooth speaker just because the Bluetooth on the EZ-B tends to disconnect and need to be reconnected once in a while. I worry that then I'd have to reconnect the speaker every once in a while too.

We'll see, but thank you everyone for the advice!
