Re: Blown Victors

We've blown a few but the worst situation was a demonstration to some elementary school students and the robot drove at them going full speed, but of course our amazing electrical guy, R2, knew something was wrong and tackled the robot,literally, and turned it off. That was pretty intense.:ahh:

I actually hooked a Victor up backwards last year. When we turned the robot on i heard a "WHRR-CLICK, WHRR-CLICK" noise. Our breakers tripped before any damage was done, so we were lucky. However, this year as a training exercise, we let our rookies take apart last year's bot. One of the rookies used a power drill with a Phillps bit in it and tightened the screws so tight that they broke off at the head. That was bad.
