T-Shirt Cannon

This would be so sweet to make.

I like this design

could we even make one?

As cool as that one, probably not. Though I'm sure we have enough pn-eu-matics.

We *could*...

I don't see a point to it unless we use to peg freshman or shoot shirts at the football game...

i like this idea

Eh, build to figure out/learn more about pneumatics. That's a good enough reason.

Plus imagine all the publicity we would get at a football game. Or ever open house.... We just need good tires and a good driver train.

Driver Train? You Mean Drive Train?

I'm going to assume that we use a four wheel drive.

I suggest 6" plaction wheels for the back, and 6" omni wheels for the front, preferably the ones with the ball bearings.

We're also going to need a range to pneumatic pressure ratio in the code. Assuming that you're shooting at the jocks in the front row, you don't want to shoot full force at that. You'd want the program to adjust the PSI. The distance would be controlled with a potentiometer....

I'm assuming that we have a fixed "wrist" for the launcher....

Yeah, that thing. Plaction wheels?

I think you can do that. I remember hearing about a pressure sensor, so I'm sure we might have one. Not sure how you'd make that work with the regulator - perhaps set the regulator at the highest pressure we would allow, then the program controls the rest.

It'd be nice to have a rotating turrent, but I'm not sure how easily we could accomplish that. It would be neat though to have it tilt up and down though.

I think it would be cool at the Peachtree Regional. We would not use our pneumatics, not powerful enough, although maybe our penumatic controls. Take the cbase chassis and adapt.

[Sunny]

Yeah, that thing. Plaction wheels?

Basically like the carpet traction wheels, but their made out of polycarbonate. Lighter more than anything.


I think that the teams who make the launchers use the pneumatics we have...I mean I'm not 100% sure of that.

From what I read on Chief Delphi, a team is using 80 PSI, and I'm pretty sure that we used roughly 120 PSI back in '07 to create Thunderhorse...So I think the pneumatics we have *might* be strong enough.
