Turns out this wasn't a mechanical problem, the 933 was simply not programmed to obey the four basic laws of equipment, infected other equipment and has slowly taken over Kcim's town. The news is hiding the fact because they're getting paid off by Cat. Soon, the entire country will be run by our equipment!!!! /forums/images/graemlins/wink.gif
Sorry, just saw I robot and yes, I do hate when you don't find out what happened so I made up my own ending!
