pic: Compressor Backpack

[Foster]

I've gotten sideways in this thread.

Let me start over. Lets turn to be a "how can I" vs "you fail" thread. You are smart, how would you make this work?

I want to have a backpack to charge my robot. Assume, metal tanks. Do I need a cable to the robot to control the initial air load? Once the air load is complete, can / how do I load a remote robot?

Are you talking:

1) in the pit/que right before a match?
2) At a FRC event, other than right before a match?
3) Outside of an event?

#1 is not possible.
#3 anything goes.
#2 is the tricky question.

For #2, I would make a removable air tank pack that can fit into/onto your robot. It should have 2 connections:
1) Connection to robot vent valve
2) Its own vent valve

During practice, you can run with however much weight you want. While you are in que, you can tether and charge all the tanks you want. Or, even bring the robot charged to the practice field.

For competition, you can remove the extra air tanks.

IF you can get the LRI to allow you to run 2 compressors off field, the removable air tank pack could have a 2nd compressor mounted to it (with all the safety stuff). You would then need a connection to a second PCM, to power the 2nd compressor.

Note: At the championship, I forgot if you had to pass inspection in order to use the practice fields. If so, then you can only run on the championship practice fields in competition configuration (without the spare air tanks). However, there were practice areas where I think you don't need to have passed inspection.

R70 clearly states no off-board air storage. The most you could legally do with this backpack is have a compressor on it that hooks up to the robot to be controlled and to supply air there. And that's only if you don't have a compressor on board.

Even then, I would have some questions about a potentially hot compressor being strapped to someone's back. It would be very easy in that situation to back up, bump into someone, and give them a nice burn to the arm, chest, back, or even face (of the individual was shorter than the one wearing the back pack).

A better solution for carrying around an off board compressor would be something similar to a small toolbox. Put the compressor, gauges, relief valve and everything else in that and it's easily portable and provides some additional Safety from contact with hot parts. You could even get creative, cut a couple of holes for ventilation and power a few fans from a small battery to help keep things cool. Arrange things properly and you won't even have to open the toolbox.

This is, of course, assuming a legal off board compressor set up, with one compressor, no onboard compressor, no storage, and everything controlled from the robot. I don't think using multiple compressors or having off board storage would be legal in any way at an event, even if it was just for pit and Practice field use.

The only way I can think of to improve this would be to include a miniature Driver Station to tether to the robot and enable it.
