Pneumatic catapult?

Is this seriously your finished drive, or an old one :P

(Although I don't doubt you could have gotten it all fabricated that fast. haha)

Re: pic: 114's completed robot
 

You figure it out. I'm sure you've got enough photos of all our old bots to be able to tell. :P

Re: pic: 114's completed robot
 

That's a no then huh :(

Re: pic: 114's completed robot
 

hey, it looks good, now you have time to practice, jk, lol, maybe.

Re: pic: 114's completed robot
 

So is this a joke?

Or is this just a frame and electrical stuff and the ball stays on the top of the chasis??:P

Do you have another photo to put??

How do you guys think to take the ball down??

I am little confused on the photo.. Another photo will help me to understand your robot:)

lol
a magician never reveals their secrets...nor does a FIRST team reveal their robot

espicially this early! it's probably the bare start or an old robot

Re: pic: 114's completed robot
 

Take a close look. The chassis is from last season. In fact, this is just a teaser. There are no such thing as a "catapult" on that robot. The ball is simply sitting on the chassis. Our team has tried few different ideas to launch it or use a catapult. It takes a lot of force to get that ball to launch upwards. I would be very surprised if I see a team succeed at launching the ball more than 20".

if this isnt a joke, ill eat my hat

Re: pic: 114's completed robot
 

Aw, ruined all the fun. But yeah, this is the 07 Drive Base. We were using it to get a feel of the ball with a robot, and so I snapped a picture and claimed it was complete.

As for a launcher that can achieve more than 20 feet, just you wait and see.

Re: pic: 114's completed robot
 

could you give us a preview of that?

possibly a picture of the ball in mid flight? :D

Re: pic: 114's completed robot
 

Nope.

Re: pic: 114's completed robot
 

is this all of the preview we get, or is there more to come?

Re: pic: 114's completed robot
 

Craig, sometimes it's okay to share. I understand that there are teams who likes to keep their robot a "secret," but at the same time if some other team needs help they show them the right path to go along; sometimes even design it for them. It is known as Gracious Professionalism.

I really would like to see a ball launch over 20 ft. I say I don't think you can launch it that high. Prove me wrong.

Re: pic: 114's completed robot
 

this is fake it is not there robot and he said 20 in not feet " signifies in ' signifies feet

Re: pic: 114's completed robot
 

I agree with Craig.... Nope.

How will the students on the other team learn anything if you design their robot for them or allow them to copy your design exactly?

Better to post a picture at the END of the build period; so they can copy it next year :]

Re: pic: 114's completed robot
 

Actually, I can't tell people about it because it's still in number crunching phase. I'll probably show it off as much as possible once it progresses further.

The true secret things don't even get mentioned.

Wait, what? Maybe if you rephrased your comment to follow the conventions of standard English, I might be able to answer this....

Re: pic: 114's completed robot
 

Be careful with the number crunching. We had a catapult design that was, in my opinion, pretty dang neat. The numbers suggested that it would work beautifully. Unfortunately, the prototype couldn't even throw a brick as desired. It also was a bit iffy as far as reliability. The first trial with a heavyish object resulted in lots of tooth skipping and massive stretch on #35 chain. After fixing that, we still had lackluster performance up until the bolts attaching the sprocket to the throwing arm bent immensely, which ending the testing.

My team managed to launch the trackball above a basketball hoop. What makes you think they couldn't launch?











(we used a rather high mechanical advantage lever w/ guides to make it go forward instead of straight up. We had a 140lbs person jump on the other side of the lever to make the ball fly)

Re: pic: 114's completed robot
 

Have you tried launching the ball using a "mechanical" device rather than having a 140 pound person jump on it?

... if so, please share a video. Thanks.

Re: pic: 114's completed robot
 

lol

Re: pic: 114's completed robot
 

We've never had any issues in the past going from numbers to the actual mechanism. It is, in fact, one of our strong points as a team. Our head arm guy is doing some quite impressive stuff to make this happen.

Uh. No, actually, it's a robot.

Re: pic: 114's completed robot
 

I think you need to pump up your ball a bit more...
