Go to Post The great thing about autonomous mode is that it doesn't require any additional effort from anyone else on your team... (You could do that yourself...but I've noticed that people will usually offer to do it for you, rather than let the programmer touch power tools.) - jgannon [more]

Re: Power for Driver Station

What we did was we hooked up a 12 volt battery to a ac adapter, and put an anderson quick connect on the other side. It worked great on the field for quick resets and charging our tanks and such. The lead inspector at our event told us that he wasnt exactly for sure what is legal and advised. He also said that knowing that tanks must charged by the compressor through the robot, that he had not a clue how we should be powering the DS. Therefore we were allowed to power it in that way. He said he would be in contact with first, so hopefully we will get that answer soon.

Re: Power for Driver Station

  1. Take a spare AC adapter with the appropriate DC barrel connector for the DS (doesn't have to be the right voltage), cut the wire.
  2. Strip and tin the loose wire ends.
  3. With a multimeter, verify which wire connects to the inside of the barrel, mark this with red electrical tape.
  4. Connect this new cable to the power distribution board with a 20A breaker
  5. Enjoy your robot-powered DS

I gave this to another team in the finals at FLR so they could do a quick reprogram, and would have done so again for team 188 but it was faster to have you guys grab the AC adapter while we went over what could be wrong on the robot. If you tie up/safely attach the DC cord, you could keep it wherever you disconnect the bridge ethernet so it's easy to swap both cables when you need a quick fix.

Re: Power for Driver Station

We used a 9v battery. It should last somewhere around an hour (but we haven't measured it, or used it that much). Should be plenty for a few emergency uses.
