Hear, hear!

Our robot had some kind of firmware issue at Standish, and got into the habit of randomly driving various motors (PWM and CAN alike) while DISABLED.

(Long story short: We took it off the field for two matches, and about all we were able to determine was that the fault was not inherent in the RIO or wiring. After re-imaging with a different laptop, the problem never recurred.)


Anyways, point is that one should never make assumptions about how these robots will behave in a given context. We always set up safety barriers at demos, and have trained robot wranglers on guard to cut the power if necessary. Safety must always come FIRST in the context of FRC!
