I'm having trouble with the initio 07 sketch for 4tronix robot. Got everything wired up correctly (I think!) and sketch uploaded but the robot just keeps going backwards even with the ultra sonic sensors disconnected. 
Anybody had the same problem? any help will be gratefully received! 
sketch attached.
Thanks

Hi, I'm having trouble with initio 01 sketch. Did you make any changes to get yours to work? I can't even get mine to do the first demo and go forwards or backwards!!! I've checked the wiring against the instructions several times but it just uploads and does nothing.
I got sketches 1 thru 4 working fine without changing anything but 07 just goes backwards; I've tried a couple of changes to the script and pointed the sensors to the sky but still the wheels go backwards!
