Yes, if you use ring terminals. Use spade terminals, and all you have to do is spin the screw about a quarter turn and pull on the terminal...it comes right out.

two things:
1. There are ring terminals on the fans that are required to be hooked up
2. sometimes getting something out so easily can be bad like in the heat and hits of a competition if someone didn't screw it on tight enough.

Re: pic: removable electronics

The Power Distribution Diagram PDF that I posted (from the FIRST website) is quite specific.

As for the quick-disconnects on the Victor outputs, which is mainly what you are trying to achieve, I think that's a great idea (as long as they don't disconnect, when you don't want them to )

Re: pic: removable electronics

I like the Powerpoles We're using the same sort of setup on our electronics this year, with powerpole connectors coming off of all the output wires for easy removable if necessary.

Re: pic: removable electronics

Forgive me for knowing next to nothing about the robot's electrical systems, but we did slightly rewire things in light of the feedback we received here. We added another of the red blocks to the DIN rail, so we have two 6 AWG wires heading to components instead of one daisy-chaining them together.

I'll ask Fred if he has a more recent photo to share.

Re: pic: removable electronics

Yes, we changed the board by adding another red block to the distribution block and another 6awg wire. I am flattered that you guys are using our board as a template

I always wanted to clean up the electronics to aid in diagnosing and troubleshooting problems, but what I found is that when you have a clean electronics board, you have much fewer (if any) problems! It solves the problems instead of making them easier to deal with

Good eye! This would seem like a violation to me, but maybe the intent of the rule is only for positive connections? But that seems like a very mixed-message. Ultimately positive and negative routes go through one wire at the battery, and if done right the intermediate connections can be as good as the yellow bridge connections on the power distribution block. Oh well, I still do understand the purpose of the rule though :/

Thanks for posting your picture!
We hope to be able to be of help to you sometime to return the favor. Thanks! My students loved your board.
