Alright guys over the months I have seen countless catapult designs each with their perks and then theres some that are just plain disappointing. Theres the forward catapult, backward catapult, the full arm catapult, forward intake catapult, backwards intake catapult. There are several more I dont remember at the moment. Which catapult do you guys believe is best and why?
This modern Catapult has a ratcheting winch that can control the distance projectiles are thrown. Crank the winch to its maximum tension and you can hurl balls over 10 feet! This cool construction set teaches kids important lessons about variable shot power and how machines store kinetic energy. Includes more than 100 easy-snap pieces, 2 balls, and instructions for 2 alternative builds. 

The catapult looks cool and does launch the balls really well, but it's also a little difficult to set up in order to launch, so kids will need to have some patience to get it to work. Once it does work, we think kids will be impressed by its performance as well as their ability to build this fully functional catapult. This STEM-based construction set makes a nice hands-on introduction to engineering, but we do wish it included more information on the science behind how catapults work and its real-world applications.
Inspired by ancient Greek and Roman designs, this modern Catapult has a ratcheting winch that can control the distance projectiles are thrown. Crank the winch to its maximum tension, and you can hurl balls over 10 feet! This construction kit challenges you to not only Build Genius™, but also build a fully functional VEX® Robotic Catapult™ at the same time! Explore the technology behind some of the most influential inventions of our culture's Age of Innovation!

What I did notice, however, was that the ball had way too much power directed in the wrong direction - so I do believe that with correct geometry, a backward launcher could also be done with just 1 piston like John's. I know it's not clear what I mean by having a forward launcher geometry flinging backwards instead, but it's late, so I'll let Aaron or Ruiqi explain for me if anybody has questions. 

Three teams in my club (mine included) are currently working to perfect our forward intake catapults which we've dubbed our rampapults. So far, none have had much success. The two teams that started working on them a few weeks ago have struggled a bit but I hear they've had some success in making them work over the break. I just got my pneumatics in the mail today so my team hasn't built ours yet but we have it designed and ready to build, so we'll see how it all goes once it's built and running.
