I've been thinking a lot about how I should post my Wall-E. Whether to post the finished product and possibly a video of a dance routine or to show the work in progress. I decided to show the work in progress and my plans in hopes to give ideas to others. And also because updates may be in long intervals.
I dont have pictures yet but will soon.
Here are my plans I want to implement.
Articulate each eye using 2 HXT900 servos. Its possible that the smaller SG-50 will work too. (Completed)
Articulate neck vertically in two places using HXT900 servos. Completed. In hindsight I should have used a stronger servo at the bottom. The additional items added to the head puts it at its limit.
Give left and right movement greater than original. (Completed)
Install a pinhole type camera beneath the head. Not inside the eye because of #5. (Completed however I havent received the receiver yet so I dont know if it will work right) UPDATE Doesn't work right.
Install BlinkM LEDs inside eyes.
Make arms move up and down.
Make arms telescope in and out using flexible pushrods. (Complete...kinda...still working out servo placements.)
Use tamiya dual motor drive. Why you ask? I want to play around with the gearing so I have enough play in it for #9. (Partially installed. Need to order a hex rod to extend the driveshaft.) UPDATE I fixed the drive shaft but in hindsight once more I could have used a modified servo and it might have worked.
Make Wall-E be able to tilt forward and back like in movie. I think this may enable him to move the front of his tread in a foot tapping motion. Hope that works. UPDATE Completed. works like a charm.
Sound capability for voice clips.
High capacity battery pack installed very low to prevent tipping. (Completed)
LOL Maybe some EL wire underneath for that ghostly glow.
I feel like I forgot something. If I remember I will edit the post.
Thank you DJ for EZ-B!!!
....and thank you to the inventors of the Dremel tool and glue gun!! Both god sends!

@choyster No reason in particular. I've been wanting to check them out and at worst I could use them in another project.
@hoolagen, Im gonna do the next Wall-e without tamiya motors just for simplicity sake and to eliminate the hbridge for space inside. @anyone who has modified servos for drive wheels: do the servos stay stiff when at a stand still? Im holding off on the extending arms until I can find thinner cables for it.
not sure if this helps but i think there is a new feature o the ezb....auto release....im assuming with will un-stiff the servo for "slack"
also, glick...are you using the relative servo motion or multiple servo motion for the body tilting.....
like you i have articulated each eye....im using the relative servo motion to control both eyes....just wondering what your doing...
thanks, Glick
@hoolagen1 I haven't worked on it in a while but I left it as individual control for the eyes and feet. I need to get back to work on the eyes. My mount point on the center came loose.
--Update-- Finished repair on eyes. Pix and video soon.
looks good man. i wish i could have gotten that wall-e instead of mine.
Dont say than man. Yours is turning out great. Plus just like you said yours has different things it can do.
epic, I am a 12 year-old-kid who is buying the ez-b right now. SOO COOL eek
