Ye i actually did. I will post a video on youtube tomorrow when I get to school.
I’m planning on refining my slip gear shooter. Do you guys think I should make it a single tower or double tower?
I’m planning on double tower to increase stability and to make sure i don’t put too much stress on one slip gear. I am however using 4 motors on my catapult because it will be a little heavier and will require more elastics
are you using slip gear? It’s gonna be almost impossible to match exactly the 2 rotations .
We have ways of doing it. Luckily a team at our school did a slip gear catapult with 2 towers for nbn
oh okay. Would u mind sharing “ways of doing it” to make sure the slip gears match exactely?
The slip gear catapult does sound like a good idea, but won’t that require that the launching platform dip down below it’s resting position before release as you fire?
If you position the ratchet correctly it will only have to go minimally farther.
Oh yeah thx. That makes sense now. Also you’re earlier post says that your two motor catapult can launch a star over the fence. If you were to shoot from the middle of your 2 pt region on your side, would that star make it into the far region?
That was actually @The_Original_Kev
I’m not completely sure about this, but would it be possible to create a launcher with just pneumatics this year (like what was done for the large balls back in nothing but net)?
Yes, especially if you use a choo-choo launcher.
I’m not sure a pneumatic launcher is the best option. You would be limited by your air pressure and the stroke of the Pistons.
So, my team has an idea for a launcher that loads the field objects into a launching area kind of thing. It then will have a gear box (I’m not going to specify too much because we still want to be unique) with wheels to start the launcher with their inertia. Then the motors will help to push the rest out at the speed.
@JustinM “If you position the ratchet correctly it will only have to go minimally farther.” Actually, if done correctly, you won’t have to go further down at all. Just crank back all the way.
@The_Breakout I agree with you about doing it correctly because you really don’t need to do all that much work the launch that jack thing in the next competition. If it does get cranked all the way back then, of coure use a slip gear, it should launch.
A ratchet isn’t necessary for a slip gear. However, a slip gear does need to rotate a few teeth past the resting position to release. How many teeth depends on the amount of force applied to the launcher.
lol our launcher has 2 slip gears and 1 ratchet gear.
I tried that for nbn @4361T and it didnt work for me. Could you tell if it works?
