KAP-V (K'nex Programmable Automated Vehicle) V2.0

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
