Discussion Overview
The discussion revolves around a T-shirt launching robot showcased at a high school football game, focusing on its design, functionality, and performance. Participants share their experiences, technical specifications, and personal aspirations related to building similar devices.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants express admiration for the robot and its operation, noting the effort put into its development over the summer.
- One participant humorously suggests that the robot could benefit from semi-automatic action and upgraded cannons.
- Technical details are provided about the robot's design, including its six-wheel drive system, the use of an existing chassis, and the specifications of the launchers and air chambers.
- There is a suggestion that aiming higher than 45 degrees could maximize distance due to the elevation of the stands.
- Participants discuss the importance of how tightly the T-shirts are rolled, indicating it affects the range of the launch.
- One participant expresses a desire to learn from the creator's knowledge and experience.
Areas of Agreement / Disagreement
Participants generally express enthusiasm for the robot and its design, but there are differing opinions on optimal launch angles and the effectiveness of the current setup, indicating that the discussion remains unresolved on certain technical aspects.
Contextual Notes
Some technical details about the robot's design and performance are shared, but there are limitations in the discussion regarding the assumptions made about launch angles and the effects of T-shirt rolling on range.

What, no semi-automatic action?
Nah, that's awesome. Would love to build something like that.
Would have to 'upgrade' the cannons though.

Integral, buddy,
Will you share the design features? Team 2168 is just about to start our own T-shirt cannon, but that one takes the cake!

Chi,
It is really pretty simple, we cheated by pulling an existing chassis out of the stack of old robots piled in the corner. It is 6 wheel drive with the center wheels 1/8" lower then the others, thus the ability to spin like it does. The entire drive train was in place, we did have to replace some gears which had been cannibalized. We used the old first controller since we can leave it in place permanently and Victors for the speed control.
The launchers are 2" diameter and 5' long. We mounted them at 45deg to maximize range and to avoid the possibility of a flat trajectory shot into the audience. I want the shirts floating down from above, not being fired down someones throat.
We have 2 compressors each charging 2 3" x 30" chambers made of schedule 80 PVC rated at 260psi. The chambers are connected to the barrels through a 1" irrigation valve which is controlled by a SPIKE and the controller.
One of the barrels is behind a check valve so that they can be charged simultaneously but fired separately.

To maximize distance you should be aiming higher than 45 degrees, since the stands are elevated.

We are pretty happy with the range as it stands. The main factor in the range is how tight we roll the teeshirt. So this gives us some control, since we have just used it twice we still have some learning to do.

Fantastic robot! 
It could replace me throwing off my t-shirt when I come back from school!

Lol, too funny! Good antics on the part of the operator. :)
