Junkyard Challenge B

[skillfullparrot7]

VERY IMPORTANT FOR CHALLENGE B.2.: You can't pull back the arm of your catapult with your hand. You must indirectly release the catapult.

Didn't know if you guys knew this already.

I also have a new length for my catapult: 1.58 meters, golf ball, pulled back by hand. When I conduct a full test of it, I will use a trigger.

Full Test: 1.03 Meters, 6 golf balls hitting the plate, with trigger

This trigger DEFINITELY makes it harder to shoot as far as pulling back with the hand.

How did you make the trigger?

[fishman100]

We have a distance of ~4 meters, and we're pretty accurate too

Does anyone have a good design for Bouncer?

Which ball are you using to get 4 meters? Also, did you use a trigger?

My best is just 136 cm with the golf ball, all 8 hitting the target plate.

Plastic golf ball and we are using a trigger (but that's our secret!) for Catapult.

And everyone seems to be fretting over a good Bouncer design; you don't really have to worry. If you find it hard, the other teams probably will too so it'll be hard for everyone.

No our bouncer and ramp are great!
But may I ask why almost everyone uses a golfball? why not tennis ball?

[fishman100]

Really? what was your design for bouncer?
And about ramp...if the Event Supervisor chooses that then we WIN. No doubt. Automatic 1st place.

my regional was only last saturday, so we have just started working on the state challenges. we have lots of ideas for catapult and ramp, but none for bouncer. so far we have been only able to build one that bounces balls about 6 inches. any ideas?
