Awesome Catapult

[rianbay812]

After being inspired by punkin chunkin, I wanted to see if anyone could replicate the catapult used by team "launchness monster"

Here's the link http://www.youtube.com/watch?v=Q_wcLy3_ ... r_embedded

I'll find a level too, one sec.

Here's your level! Let's see how good at replicating we can do!

jeez that catapult is freaking beast,

I remember seeing another one where the whole thing fell down a metal track and then pulted the pumpkin. You know the name of that one by any chance?

[edit] heeeere we go http://www.youtube.com/watch?v=u1s1juID ... re=related

That one looks fun too!

Here's what I have for the first one

this looks to have more leverage

lookin good so far rian. heres a better video of merlin http://www.youtube.com/watch?v=WcNITnbk ... re=related skip to 2:40

I like that one.
The weight stays on the same track and the catapult goes on the other one. hhhmmmm

that's awesome!!!! We don't have the right type of building area for that one

Here's Launchness:

as yoo can c itz fairly inefficient,
considering the enormous amount of weight i put on it compared to how little it goes.

Edit:
actually, i added some torque and gave it some moar power,
but still i doubt its efficiency

I think adding a roller makes it more efficient.... BTW very cool design Jyo

You guys are doing something wrong.

Here's what I got, directly from the video:

http://www.fantasticcontraption.com/?designId=11304395

Sure, the timing is off; it's supposed to shoot the other way, and the weight it sloppy. Also, bear in mind that this is a Low-weight version, and a higher-weight one would have a Sling, which would drastically increase the weight/power ratio.

This is a very simplified version, that might help. (Also, the initial start method could be used as a trigger.) http://www.youtube.com/watch?v=oKNbs5jz ... re=related

However, I'm not sure how Jyo got that design, but it doesn't seem very accurate. This sort of catapult WORKS on the fact that the weight falls a greater distance than usual, which is why a standard weight system doesn't seem to work well.


For the record, my design uses 29,227.433674366 Mass units of weight, compared to Jyo's uses 168,023.42271862.

I win.

However, I still agree that this is rather inefficient...
Here's a non-optimized using of the weight, and because it achieves a similar amount of "Fall", it has a similar amount of thrust.

Edit: Sorry if this sounds somewhat offensive. I did not mean it that way!

[Jyo]

thnx Chris;
made me realize that the launching force is greater when itz impulsive rather than continuous:

Here is a more real version.

Added more propulsion on the end of the arm http://www.fantasticcontraption.com/?designId=11304758

just tweaked the position of the goal ball http://www.fantasticcontraption.com/?designId=11309131

Yea but i didnt like the wheel launching also D:
