Ball intake help

So I’m going the double catapult route which means the ball loads in one end and fires out the other side which means the ball goes up and outwards.

As you can see from the picture, i really have no idea what im doing please help

Your off to a great start, but you might want to add no slip material to the ball intake. Also team 8059 nailed the double catapult here is a link to their video

Do you know of any sites that sell legal alternatives for anti slip mat or is vex the only place to buy from?

It’s also sold at stores like Home Depot as drawer liners and router mats.

Watching a few nbn reveal videos might help you with the intake because you can see how different people have built their intakes differently for different setups, but have some general principles in common. Here are some to start you off:

is it like this or like this?

sorry if this seems really trivial but I’ve never handled actual slip mat before

Yes, that’s it. HOWEVER, as you know, it has to be identical to that which VEX supplies. So if you get busted for Home Depot non-slip by an Inspector, you didn’t hear it from me. On the other hand, non-slip is all pretty much the same, and I’ve never heard of an Inspector being upset by non-VEX mat.*

*OK, I did once, when a team showed up with white non-slip mat and the Inspector felt that it had to be gray, like the VEX mat. After discussion with the event partner and head Inspector, they were passed.

hmm, <R7>, Any parts which are identical to legal VEX parts. For the purposes of this rule, products which
are identical in all ways except for color are permissible. It is up to inspectors to determine
whether a component is “identical” to an official VEX component, was your friend I guess

thanks for the help, I’ll see when I can pick some up

It seems that they all use a c channel on the bottom to mount their thing that goes up. Thanks, I’ll try it out tomorrow.

I think I got the right one IMG_20180911_192321.jpg

@Vyx that anti-slip mat looks legal.

Why do a lot of teams stick the chain over the rubber banded sprocket? Why don’t they use a seperate sprocket to better insure that the chain won’t slip off?

Might be because of space, or they might have tested and just determined that the risk is negligible. I might test it some tomorrow as I am starting on my ball intake likely.

Usually in the interest of saving space.
