pic: T-Shirt Cannon Bot Concept WIP

[Kyle Butzerin]

We are a fairly average team looking for advice on a T-Shirt Robot. The idea is to train our team (Which doubled in size last week to over 25 members) by constructing this robot.

Here is just the cannon piece, this is already built and we are trying to fire a shirt more than a few inches (at 90-100 psi). https://grabcad.com/library/t-shirt-cannon-prototype-1


Reason being that we are using a sprinkler valve that was suggested to us: (http://www.homedepot.com/p/Orbit-1-i...7101/100006711) We are going to modify the valve, supposedly using something along these lines, which may present challenges: http://www.thehalls-in-bfe.com/GGDT/...rbit1_mod.html

So I ask my questions,
Are there valves that will release the stored air we need to propel the shirt through a 4" barrel without modification? If so, what can you suggest?

Should we go with the air storage I have in the model, or something else? Should we charge it up with a ViAir? or a better Compressor?

Are there any good ideas to lift the barrel? We are wanting to use the Lead Screw method that our 2013 team went to St. Louis, but we are open to new ideas.

Thanks!
