I was walking through the Super Store buying groceries one night, when I took my usual detour through the toys section and spotted Wall-E. This is a toy made by Disney that was truely the most annoying and dissapointing item since the stupid iRobot Dinasourp.
This "toy" merely make wierd smashing noises and waves it's arms and head around. The box advertises "interactivity"... Other then the smashing noises, it does aboslutely nothing. It doesn't even move!!!! Only it's arms move, and they are animated together by a gear assembly and a single motor. Boo Hoo! Oh well, it was $22.95!
Enough of that!!
I took it apon myself to build a REAL Wall-E. That's fun and independent, etc.. I wanted to use the shell to make an autonomous version... And guess what? After some brainstorming, i decided that i can do it. Maybe...
I modified the circuit that came with the toy and stole it's eeprom. So now i can trigger the Wall-E samples "WALL-E and EVAH" etc.. :)
- 1 EZ-B EZ-Robot Kit: http://www.ez-robot.com
- 2 GWS Nano servos for arms
- 1 GWS Pico servo for head tilting
- 2 modified parallex servos for movement treads
- 1 GWS regular servo for head left right
- 18F4685 microcontroller @ 20 mhz for brain
- 1 Sharp IR Distance sensor to see with
- My custom 40 pin PIC board ;)
So far he does lots of things. He's autonomous, which means he drives around and explores the world. He maps out his world in a 2D array stored in memory. His job isn't purely to drive around, as you can see in some of these videos, he has many animations and emotions...
So he pretty much has joined my collection of robot pets. The idea is to write the program so he doesn't get stuck or require interaction. Instead, he just does his own thing, looking for evah!
