Im with Eric Scheuing on this, How will it get balls during comp? Throwing into that hole seems hard.

I love the throw on this thing. Reminds me of Mythbusters when they built the card throwing thing. Very cool.

-the loader shown is a prototype. Balls will be collected from the ground via the belt mechanism and/or thrown into a basket (not shown) which feeds the loading tube.
-roller bearings with integral clutching are used for the arm
-not sure which video was posted but most of them were shot at about 20' range.
-trajectory angle is not adjustable in-match. It could be, but we're not trying to. Properly tuned it can score from a wide range of distances from target without adjustment
-in order to aim, the driver and/or camera need to aim the entire bot.
-the radar gun was behind the launcher. They work in either direction. Can't speak to the accuracy of this gun at this speed range though.

looking good!!!!!
what is your drive - train?
What is your basic strategy?- aim higheror bottom feed?
what are you guys better at defense or offense?
what are you doing during autonomous mode?

4 wheel drive (makes turning difficult, we need to replace front wheels with something slicker)

Well we can do both so it dosen't really matter... at the scrimmage yesterday we discovered that our lift uses the most power of anything on our bot. We basically relied on human loading as much as we could.

I would say offense in that we don't have the strongest drive train ever. One benifit to both sides however, is that our release point is about at 4.5 feet. At the scrimmage yesterday only one of our shots was blocked. We did get pushed around a little bit though.

Well.. as of now, nothing. Our programmers have their work cut out for them, as we were hoping to utilize the camera to get into position and fire in the beginning of the match. They make it sound like we will not be able to do that, but time will tell.

You must be using a one-way roller clutch so that the rubber band can over run the van door motor. Very clever.

• Lets the elastic take over when it needs to.
• Doesn't require an elaborate catch.
• Rapid firing without complex sequencing issues.
• Allows the "follow through" of the arm to partially wind the arm for the next toss.
• van door motor starts rewind automatically when the arm slows down

Beautiful!

I had my doubts about the feasability of making a rapid fire catapult.

But, you ave done a great job, one that I think has a chance to compete with the pitching machine solutions.

Well done.

how far back were you shooting from in the video

Wow, that is a really cool shooting mechanism! How did you come up with that idea? Did you base it off of a batting cage launcher?

[Chris_Elston]

Great job guys.

The only comment I have though.


I don't know much about measuring with a radar gun, are you suppose to measure the ball on coming into the radar gun or away from the radar gun?

It looked to me in the video you are measuring your Poofy Balls as it was leaving the range of your radar gun.

Which way should it be or more accurate to make sure the reading you are getting from the gun is indeed what it says it is?

In the video we were shooting from about 20 feet

Very nice.

[Dan Petrovic]

Wow

That's really impressive. I wasn't expecting to see anyone using a catapault assembly for their launching mechanism.

[LightWaves1636]

Awesome shooter! I really love the design and idea. The best use of a catapult ever!

It appears you have exceeded your bandwidth limit on your website? This I cant watch

If you would like it hosted at another location I can host the file for you, or there is also mediaputfile I believe it is?
