Our school actually asked us to build a t-shirt cannon for rallies, and they actually reimbursed us on the cost of the parts, so that was pretty cool.

RE: What it's called?

First of all, I call it "cool"!

Trebuchets were the ultimate development of the stationary flinging-arm military weapon, but by the 14th century they were being overtaken by early cannon. Since no one alive now speaks a 14th century dialect, we are unlikely to be using the proper name in 21st century English, especially since I doubt medieval siege engines used in probably dozens of different kingdoms, duchies, and counties were all called the same thing. I believe were are applying our modern passion for rigid definitions to devices created in a time where no such cladistic hegemony existed.

Not entirely sure but i believe the term was changed during the Mongolian rule of Central Asia... or at least the Khan or Seljuk Turks created a different type and changed the terms..

doesn't a trebuchet have a mass one one side of its arm instead of surgical tubing?

Well, what people have been saying is that a trebuchet uses a weight and not a spring, so it sholud be called a catapult, but a catapult doesn't have a sling, so it should be a trebuchet.

let's just call it a "Catachet"

And the video should come soon, Bannanakin is (attempting to) upload it to Youtube.

I really hope that that CAD was not made in Inventor provided for FIRST....
(That may violate the EULA! Oh Noes!)
Sweet "Catachet" though!
Maybe our team should make an pneumatic catapult...

I don't believe that would violate the EULA for the FIRST provided inventor. I haven't used it in a few years, but IIRC it's simply the educational version which means that the only restriction is that you are not allowed to use it for any commercial products (ie anything you would be making money off of). This is clearly a non-commercial product.

The CAD was made using a student edition of SolidWorks.

Smart school, very smart. They understand partnership, promotion, supporting students interested how things work and like to build them, and fun. They also understand the value of a product. Smart.

Don, I just read your very bad pun. It rocks!

My family makes puns all of the time, but even by our standards, geez, these are bad! And for reference, the term "almost completely safe" can always be disproven. There's blood on the sidewalk at my middle school from when I did a video project with rubber chickens. If there's enough force to hurl a couple of pounds over a football field's distance, there's enough force to cause damage.

If these are bad, you haven't been around long enough. (There are some threads that were, for a while, almost solid puns. There are about a half-dozen people that you don't give a punny topic to, because they will go after it to the full extent of the humor.)

(emphasis mine)

Making a good point, and something we always need to keep in mind, we can think that because the robot is only shooting tennis balls (you never know) that the shooter can't hurt us. If something is moving you need to be alert, and you need to make sure you take all precautions.

If it doesn't rain tomorrow, we will be shooting some video of the "catachet" in high quality and at 240 fps.
