Re: Communication from Arduino to Roborio

To answer the first part of your question: in the past there has not been a limit on the number of custom circuits in the robot, other than that all other rules must be followed such as what the...

Re: pic: In-Line Pneumatic Fittings

I'm going to be emailing Rick Folea on Monday to ask him that. It just so happens that it's a small world, and a long time ago in another place and time we used to work together :)

Re: pic: In-Line Pneumatic Fittings

And the spec sheet only says that it regulates from 15-120 PSI. Based on that, it does not meet the 125 PSI requirement in the 2015 rules. I know it passed inspection this year, but that does not...

Re: ATTN CMP teams: Lock up your stuff!

I can say with 100% certainty that my loss was not due to any FIRST participant. I want to make it entirely clear that I do not suspect anyone associated with the program for my loss.

Re: pic: Compressor Fan Mount

I'll throw my opinion in here (and as I am the LRI at your week 1 event, you may want to know what it is..... )

Re: No Bag and Tag Inspection at Championship

As your division (Galileo) LRI, I'll answer this. We would prefer for you to get the robot finished and then come to the inspection station to weigh and start the inspection process. The way to...

Re: FIRST Babies

The C++ and physics books are good, but Henry Petroski's "Invention by Design" is AWESOME!!

Re: Al's Annual Inspection Thread

No. You can expect any stored energy launcher that, upon review by the LRI, appears to present a risk of catastrophic failure resulting in parts leaving the robot, to probably be dry fired in a safe...

If it is obvious that when your shooter self destructs that all shrapnel will be contained safely inside the robot, then it would not be necessary to dry-fire the mechanism. The safety concern is...

Re: Al's Annual Inspection Thread

I personally do not trust any sort of "software interlock" to prevent a dry fire of a robot mechanism. We all know that programmers are allowed to tinker with the code after inspection, and there is...

Re: Dry Ice on Robot?

What are you using it for?

My opinion would be that if it is doing anything useful (providing cooling) then it is an illegal energy source, as the energy for creating the dry ice did not come from...
