Shutting Down a Robot-Mounted Pi

Integral means like the battery that comes with your laptop.

This topic has been done extensively elsewhere on the forum.
Adding a battery to the Raspberry PI violates the rules unless you can buy a package from somewhere that has the PI and the battery packaged together. That source (store) needs to be able to sell to the general public.

All of these teams have 3D printers and are not interested in a revenue source entrepreneurs award.

If nobody wants to jumps on this I'll start a company tomorrow to sell you one.

Need a website and other stuff to prove you have a proper business for the general public. It's not actually that hard: I just am too busy with other things to sell an assembled Raspberry PI in the case with the battery to someone.

Worse there's nothing stopping someone then from placing a really big order which means unless you have a large pile of the Raspberry PI handy...

So you say I'm almost guaranteed to sell a few hundred to prove I can keep up with demand? I'm not hearing the problem.

Adafruit will sell me 85 per order

What are you waiting for
Are you done yet? (quoting an old college professor 10 minutes into every test)
Can we buy one?

Remember you need a way to charge that integrated battery as well.
If you sell this under COTS there's no minimum sale requirement - just that people in general can buy them.
If you take this product into FIRST approval that's a more complex and lengthy process you will not complete this season.

In 2012 we used a linux single-board computer on our robot and had to solve the shutdown problem. There are some details in this document:

Our final solution assumes that you've written a program on your vision processing computer that can respond to packets it recieves from the RoboRio or other computers. Our robot computer (crio at the time) sent a packet to the vision co-processor which caused it to run the shutdown script. We triggered all of this with a button on one of the joysticks at the drive station. For what it is, it was a lot of work to get right but we didn't want that 1 in a million chance of our vision computer corrupting its file system at the wrong time.

Has anyone looked into the legality of this?

I'm going to ask on the Q&A myself tonight.

What worries me about that is the battery does not appear to have a fuse between it and the rest of the system. So that's the sort of battery I wouldn't want to overload and there are exposed pins that could overload that battery all over the place.

I await the Q&A response, but I expect this would not be legal, as it's not integral to the cots computing device. It's an add-on, but I suspect it is just outside the line. Could be an interesting option if they rule it legal.
