 Feelings are like the laws of physics: if some one feels offended or alienated, then they are offended or alienated - it doesnt matter why you dropped a hammer, if it falls on someones head they will be hurt. You cant expect it to not hurt, because you did not intend to hurt them. - KenWittlief [more] |

Re: USB Joystick adaptor is here!
So as I see it the question is, can FIRST ensure safety on the field while allowing externally powered devices connected to the O/I joystick ports? Maybe their answer is no. Or maybe it is yes[/quote]
The answer, I believe is yes. Of course I'm biased... Actually pulling power from the comp port should not be a saftey issue. The robot's are disabled via the mode bits. I believe, not certain, that the E-stop kills power to the O/I. With these saftey features already in place there is no reason, other than the rules, that pulling power form the comp port, would be unsafe. I agree that custom circuits should not be allowed use external power sources.
