Task 1 - finding the YouTubes

Simple Arduino Robot - about as simple as you can get: 2 driving wheels, front idler, breadboard mounting - on ours we'd put the H-bridge there..






Easy Arduino Robot - also fairly simple; a bit fuzzy but if you check out the video, it's clearer: this one has an IR sensor (i think) for detecting obstacles so i guess it has software to do this..






Arduino Robot controlled by Neural Network - i threw this one in, because i'm fascinated by Neural Networks & what they can do.  more here..
i have a few very basic C programs @home which i hope to translate into "Arduino-ese"..
This thing actually learns, & it's funny to watch its bumbling first attempts & then see it 'get the idea' & learn to avoid the obstacles.  it also learn how to avoid new obstacles once it knows how to navigate round the old ones..
  PlanMix says:   
" My first attempt in neural networks. I connected
  - 1 adruino mega,
  - 3 servos,
  - 1 analog infrared receiver,
  - 3 contacts and
  - 2 encoders from an old printer.
  I use a genetic algorithm that trains the 5-7-2 neural network
  (5 inputs, 7 neurons in the hidden layer and 2 in output).
  The 5 inputs are the 5 areas that the IR scans using the third servo, and
   the 2 outputs are the speed of each wheel servo."[03 dec 2009]
(Unfortunately for me, his website's in Greek :-?, so that's all i have)
