Go to Post OUR CNC machine is named Joe, and he has this week of school off. He eats candy instead of electricity. Not so accurate or repeatable, but very easy to re-program. - Not2B [more]

Re: pic: Team Fusion's T-Shirt Shooting Robot

Haha, it must be something with mentors, ours is having more fun than we are I think! We send the shirts at about 80- 100 psi, no regulator. We're just watching the gauge right now, but intend to use a pressure sensor in a bit.
What we've found, although it's still in it's infant stages, is that you begin to drop off with distance increasing after about 80 psi. You get about 3-5 yards further with that extra 20 psi, but thats it. Might be the weight of the shirt. But boy is it accurate. We can consistently put it into about a 3 yard circle at 30 yards. Its pretty fun to see is load the thing though: we use a shovel handle and ram the thing down in for a nice tight seal. It looks like you're seriously loading a cannon. The place where we fire it is on an access road behind our school that gets quite a bit of traffic, teacher and otherwise. We get some awful strange looks in the morning! I am considering the ballistics table once we get the thing consistent.
