Basic Fundamentals of a catapult?

My team is probably going to destroy our DR4B, and replace it with a catapult. What are some basic things/tips that we need to know to build one?

Look at the Herobot “Fling” from 2021-2022 season,

Also check out the various video on “Choo Choo” mechanisms.

Note, this is an example that requires a lot of trial and error to get the results you want.

Good luck

I am not sure about the catapult, but I think you should break the DR4B into 2 4B arms and have them on the back left and back right of the robot, raised up over the wheels with a platform and point the end of the arms to the back, and add intakes. I am sorry I wrote it that way, but to me it makes a bit more sense.

I would recommend the swish gear box. Instructions Online by Cadasio.com
