The up and coming movie from Pixar on June 27th, 2008 entitled "Wall-E" appeals to me, as I am into robotics and science fiction movies. So, I Googled Wall-E and found a few movie clips and enjoyed them all. So, I began a quest to build a small scale model after speaking with folks on this forum. The criteria for this project were that it could be constructed with materials at hand in my workshop, with the exception of the tracked base unit (which is a set of Mattracks that were ideal for this project.) Also, a set of sensors would make this project autonomous. GWJax will be doing the PBasic programming for the Wall-E. The criteria are as follows:
Use my Mattracks as the main drive unit
Motor drive gear motors using H bridge controllers
Pan/tilt head using Parallax ultra sonic ping
3 GP2D12 IR edge detectors or similar detectors
raise and lower the arms as a pair [up and down only]
raise and lower the front door
[Maybe not sure yet] raise and lower the head
Use Parallax ping in both eyes
airbrush Wall-E to look authentic as possible.
Fit a uOLED in the front panel
Use a Parallax emic text to speech chip for wall-e's voice
Fit Ultra bright blue LEDs in Wall-E's eyes
Make a pair of H bridges for the drive motors
Here are some pictures from the movie, so you can see what I am up against:
As you can see from these movie clips (Thanks Nocturnal, R/C, and whit from Parallax.) I have my work cut out for me! We are going to do a digest of pictures and text to give you an overview of the project - you can click through to the main thread to see more details. Stay tuned; I will be making a full report of the project when it is complete!
Before I begin, I would just like to say that belonging to this forum is great, and I encourage you to sign up if you are into robotics! You will enjoy all the contributions that are given here. There are a lot of talented people here and it's a great way to get into robotics. And last, but not least, Capable Networks and RoboCommunity for allowing us to express our desires.
Grippers and arms are made from LEGO Technics, I had to sacrifice some parts here that are never to rejoin the Technics set. Both air rams are glued back to back and the grippers had to be cut to get the correct shape.
1mm ply parts for the arms.
Parts for the arms.
Modifications to the grippers.
1mm Ply parts for the grippers.
Grippers complete.
More ply and balsa to form the metal panel effects.
Circuit diagram, notice the CDs on Wall-E's head, this is to turn the lights on when he encounters a dark corner or when the house lights are turned off.
This was to test the LEDs, The ping sensor has to go in front of the LEDs yet.
