Re: encoder vs. motor

Everybody has been focusing on the programming, but nobody has answered the other question:

If you don't already have a "competition dongle" to plug into the top port of your OI, make one now. One of the pins on the competition port will disable the robot, shutting off all its outputs. See the Competition Port Pinout Guide on the Innovation First web site.

A couple of weeks ago I put together a mini-dongle, with the "disable" toggle switch built into a plastic DB-15 connector housing (the extra channel access is wired to be permanently active, and autonomous control is not available). It's mostly going to be used when someone is working on the robot and doesn't want it to bite them if a joystick gets bumped. It'll also come in handy when we want to have multiple robots running at the same time.
