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.
My son received this as a birthday present when he was 4 years old. He was able to build most of this himself, with me reading the instructions for him. He loves playing with this and often takes it apart to build the car and different versions. Since then, I have ordered additional sets to give as gifts to his friends who are turning 5-10. This is a great alternative to Lego. This holds together very well and does not fall apart when he or his friends are playing with it.
The positives to a front catapult is that you only need half of everything because the degrees of motion is basically half of what a backwards catapult is. I've only seen backwards catapults with 4 pistons and only front catapults with 2 pistons. Does that mean if someone gets a backwards catapult with 2 pistons a front catapult would only need one? :eek: Probably impossible if you're following the rules on pressure. The front catapult can also actually act as an assist to get big balls out quicker so you don't have to wait for intake to spit it out or if you can't get the ball out of your intake at all. I've found this to be helpful.
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?

Hexbug is a brand name of toy automations that have been developed by Innovation First. Hexbug was initially inspired by BEAM robotic, which is why you find lots of components of it in the toys. They were originally released in the United States through RadioShack, but today, you can find that it is sold in the majority of significant retailers. The original was based upon 6-legged arthropods, but now, today, you will find them being offered in many varieties. The name “Hexbug,” nevertheless, isn’t truly used to explain the variety of legs the toy has– the name has more to do with the shape of the product packaging.

This construction kit challenges you to build a fully functional VEX Robotic Catapult! Explore the technology behind some of the most influential inventions of our culture's Age of Innovation! 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 3 m (10 feet)! Teaches important STEM principles through hands on learning. Features two alternate builds for more robotic fun! Two balls included. Batteries not required. 8+ years.
In addition if someone has a 4/4/2 (four motor drive, four lift, two intake) setup then having 4 tanks on your robot for a backwards catapult is a lot of weight. The tanks aren't light so keeping your robot as lightweight as possible with only four motors on drive is essential. But then again team 1103 in Round Up had a rock solid robot that weighed nearly 20 lbs. (I believe he said this in a video somewhere, don't quote me on it) and had only 4 high speed motors on his drive. Very impressive!

It took us one hour to build this set. It is listed as being a beginner skill level build that can take anywhere from one to two hours to complete, depending on your skill level. The instructions were picture-only instructions and were a little confusing as were the picture directions for how to use the catapult. Also, the knob fell off quite often, but reattaching it was easy.
