The Only Rubber Band Intake Tutorial You'll Need (Step by Step Guide)

Join the community & access CAD files, Code snippets, & more robotics resources ⤵️ https://shop.broganpratt.com/ Want to work with me and get support on your project? ⤵️ https://cal.com/brogan-pratt-a4gcx7 Summary ⤵️ In this video, I break down one of the most effective and simple designs in competitive robotics: the rubber band compliant intake. I'll walk you through the entire build process step-by-step, from the basic principles of compliance to the specific geometry you need to pick up spherical objects reliably. I cover material choices, how to properly anchor your rubber bands, and the design tricks I use for my own robots. This design is cheap, easy to prototype, and effective.

Why Watch? If this is your first view—hi, I’m Brogan! TLDR: I've been teaching robotics and design for over ten years. Today, lots of people talk about robotics but I’ve noticed that very few have practical, real world ways of teaching people to create their own robots. So this channel is me chiming in and showing you what it really takes to build your own. Hopefully I can help you improve your projects and robots, and in doing so, the rest of your life 🙏 Like, subscribe, and leave me a comment if you have a specific request! Thanks.
