Re: Building an arena controller

I built a field controller based on the edu controller. What pin on the competition port is the e-stop? In order to effectivly control the units, i hooked the power supply up to a relay, and used Kevin Watson's ttl interface to control the system from a laptop. It was an arena controller uber ghetto edition, but it worked. I talked to one of the IFI people. They are somewhat touchy about the chanell changing, however, I think that they might be willing to release the e-stop and disable ports, because of the safety issue related to running a scrimage w/o e-stop and using powerdown to disable.

Finally a note on the field controller. Hatch chose to create a system this year in which there was no hardware control panel. As a result the official field had as long as 2 sec latency between a robot disable, and the actual robot disable.
