I need help with designing my disc launcher in VRC spin up so if possible can someone send me a close of how there launcher is working to shoot the discs.
Welcome to the vexforum!
If you are looking for something you can “hole count” or copy, it’s highly unlikely that any team will share such detailed plans with you. I would encourage beginning teams to build one of the pre-designed trainers, found here: V5 Build Instructions - Downloads - V5 - VEX Robotics . These pre-designed trainer-builds represent generally good-quality building techniques (especially the “V5 Clawbot”) so you can learn the VEX building system. Each season, a new pre-designed game-specific trainer is offered (this year it is called Disco) to provide a starting point for teams to compete in early competition: typically a robot with good build quality but deliberately mediocre game performance. Once you have become familiar with the VEX building system, you can begin to look at pictures, youtube videos, game reveals, etc, for inspiration, then work through the engineering design process to build your own unique mechanism.
VEX has a great resource for beginning teams to learn the design process and how to make decisions. Take a look here, and especially look at the “engineering” section to see how experienced teams have worked through making their design decisions: https://kb.roboticseducation.org/hc/en-us/articles/8373753632407-Students-Start-Here
