Re: Linear Shooters - How did you do it?

How did simbotics or any other similar team make it effective?
(Was it even pneumatic?)

<edit>
Just noticed that Simbotics was not pneumatic - but how did it work?
did anyone manage a linear shooter with pneumatics?

just curios...

We originally had a linear cylinder on our arm to push the ball over the overpass. We did some tests with different cylinders, but were not happy with the results. We never tried the latching technique as we decided to build a "drop kick" device. This mechanism used a 1 /12" bore cylinder to kick the ball shortly after it was dropped from our arm. After some debate, and some time lapse photos we realized we had more of a Jai-alai stick. After a few small modications, we came up with a result we much happier with. This mechanism allows us to throw the ball from about 8 feet from the overpass, while we are moving. This gives us enough time to drop and go under overpass without slowing down. It also turned out to help us cradle the ball, before the pickup. This video has been posted before, but for those of you who haven't seen this:

We can't wait for CTR later this week.
