Any help with making a pickup quickly?

Hello, this is team 24658J. We just qualified for worlds and are looking into making a pickup system for our robot before then. Ive been looking into a rubber band pickup but dont know how to make it. We are kinda stressed on time so if there is any help we could get on how to make a pick up like this and if there is any other pickup system that would be eaiser to make?

I would suggest looking through youtube there is always a lot of examples as well as explanations there.

Check out the Mentorbuilt robot reveal on the forum, they used a rubber bad intake.
