This is my second robot- thanks for the comments!
Improvements over Mk1:

Large program length (20 Chain links)
It takes much less of the program to turn (5-6 white pegs instead of 12 in the old one to turn 90 degrees!)
Smaller, more compact design
Quite tough- the old one was flimsy
All-in-one program unit and chassis-yeah monocoque (if you don't know what it means go on wikipedia)
Faster- Bigger wheels
Only 4 red gears because of the direct drive to the wheels

Con's:
Only works well on flat, smooth surfaces because of low ground clearance- so I couldn't put castor wheels on it- I put skids on instead
Jerky movement due to new pick up wheels

    I built this now, but the chain keeps faling apart and their is too much friction against the white connectors that help the chain a long the bottom.

    How many chain links are used? Btw, this is AMAZING.

     Ah, I have noticed this, I will post a third version which will resolve this problem, an it will have a castor wheel - Are you referring to the white rods on the chain?

    You could invert the chain. So when it gets to where it used to fall off it just pushes it in tighter.

     The problem is that it catches on the side of the body, so it needs to be widened. I will post instructions when my arm is better
