    1st Place Wall-E

    This is my Wall-E project that I am currently working on it is 150mm x 150mm x 160 high, it uses a pair of Mattracks http://www.litefootatv.com/html/lite...n_the_news.htm for motive power and two robosapienV2 hip motors. It will be controlled by a BS2P40 stamp CPU and will have the following functions described below.

    I build robots quite prolific but my let down is programing "hopeless but learning" I have a friend at http://www.robocommunity.com who is programing it for me, From this I hope to learn how this program is put together and eventually program myself. We are in the progress of designing the H-bridge for the motors using the L298 chip, The head is finished apart from his adorable eyebrows which http://www.musclewires.com/shapememoryalloys.shtml wire or Muscle flex and pan/tilt has been run.

    The main reason for building this project was to see if I could use parts from my stock of components that I have lying around my basement and electronics room, The only thing so far that I have had to buy is the Mattracks , uOLED screen and L298 H-bridge ic. Which GWJax is sending me. I was inspired to build this project after seeing a Pixar demo video and thought WOW what a neat bot to build.

    I have been in R/C scale and other unorthodox aircraft for over 30yrs and modeling is my passion, so this comes in handy when creating something like Wall-E. I hope you like how it is coming along. I would also like to add that GWJax has been an inspiration to me on the programming side.The main construction of Wall-E is 5mm lite ply, sides,front,back and top, with 2mm balsa cladding on the sides with some 1.5mm ply to form the raised panels. Rivets were made using PVA glue watered down 40% and applied to the required area's with a sharp pointed rod, One dip will give you 3 rivets. The arms were constructed out of 1.5mm ply and balsa, and uses 4 of my Technics air rams back to back, The fingers were modded Technics angle beams covered in 1mm ply for the sides and balsa top and bottom.

    The base is constructed out of 5mm Acrylic sheet as this is good for boring holes to mount your fittings. the head H'mmm a real challenge here, I had to draw it out first to get the pear shaped eye right then work from there. The main eye tube was a pair of alloy pill containers which worked out to be the right size for the head. The Blue LEDs x 6, 3 in each eye are mounted on a 5mm acrylic disc and inserted in the tube about 2/3rds down, then another Acrylic disc in front with the ping sonar in each eye.The ping sonar is from TX and RX had to be removed from the board [tricky and an extension lead screened run from the board to the Tx and RX in each eye. I was not sure at the time if this would alter the characteristics of the range, but after testing this was unfounded.

    The eyes light up at present using a circuit which has a CDS cell and when you switch the lights of the eyes come on, GWJax may code this to work also with some other functions on Wall-E.Wall-E was finished with off the shelf spraykote enamel cans, grey primer, followed by antirust primer, then layered with yellow, rivets applied, then sliver over the rivet area, followed by an airbrushed rust over the rivets. The whole body was then rubbed with scotchbrite pads until the rust and some silver was showing through, then airbrushed with a mix of satin varnish and grey primer to give Wall-E that weathered effect.The head was done in a similar way but with different colors. Phew, I think that's it guys. Check out my web site.

    1. Use my Mattracks as the main drive unit
    2. Motor drive gear motors using H bridge controllers
    3. Pan/tilt head using Parallax ultra sonic ping
    4. 3 GP2D12 IR edge detectors or similar detectors
    5. raise and lower the arms as a pair [up and down only]
    6. raise and lower the front door
    7. [Maybe not sure yet] raise and lower the head
    8.Use Parallax ping in both eyes
    9. airbrush Wall-E to look authentic as possible.
    10. Fit a uOLED in the front panel
    11. Use a Parallax emic text to speech chip for wall-e's voice
    12. Fit Ultra bright blue LEDs in Wall-E's eyes
    13. Make a pair of H bridges for the drive motors
    14. solar cell to charge batteries
    15. voice changer circuit for Emic text to speech
    16. Speaker


    Wall-E


    This is what I am basing my Wall-E from.

    http://www.youtube.com/watch?v=baI3NTfTNLg Wall-e's first head movments, crap servos, need to change them.

    http://www.youtube.com/watch?v=79jfrUYDv0M Different servos, head movment a lot better.

    http://www.youtube.com/watch?v=2TTCUqtGsBw Components added, looking more like Wall-E

    http://www.youtube.com/watch?v=GM0EwTtUZQQ LED eyes now in place.

    That is amazing! The movie isn't even out yet and you already have one made. Nice work, I look forward to more videos.

    What ^^ He Said!

    I just went and looked at the trailers again - wow! You've really captured him! Pixar should be afraid, and Disney should be hiring you.

    umm..... WOW! I'm pretty much speechless. Seriously, I don't know what to say about this. I'm just in total Awe... I'll have to reply to this thread again later when my brain recovers a bit

    WOW, You didn't waste any time on getting this moving! I can't believe how far this project is already. Are you in animatronics already or something similar? I think this movie will do very well. It's not even out yet and it's captured the hearts of many. Nice work!

    Re: Wall-E

    Hey, Thanks guys, very much appreciated. I am not in animatronics [love to be though] I'm just a cabinate maker. I have over 200 pics to date and posted about 1/3 on Robocommunity another forum I am on, I have to complete Wall-E on Robocommunity first and do an article as this is the forum I started it on, but will post equal pics here as I go. Just trying to navigate around this site as it is quite different to robocommunity site.
    It's really nice to be here. Thanks.

    Ply box taking shape.



    Front section added, the sq hole is for a uOLED screen.



    Another front shot.



    Side shot.



    Side panels added to give detail, also arms.



    Front/side angle, notice the led bar graph to the right of the uOLED opening.



    Front door and grippers, this door will come down and up via a pot sensing system to the stamp.
