How 4-Bar Linkages Work

This video clearly explains how a 4-bar lift works on a robot, covering its mechanics, common build methods, and practical uses. ✅ Subscribe! bit.ly/SubscribeBMPratt ⤵️ Why Watch? Ever wondered how robots lift things so smoothly and keep them level? We'll break down the core mechanics of a 4-bar linkage and see the reason behind its parallel motion, show you common ways these lifts are constructed using practical examples and models, and discuss why they are so incredibly useful in many robot designs (plus a few situations where they might not be the best choice). By the end of this video, you'll understand this clever piece of engineering and how it can make robots more effective. 🔧 1:1 CONSULTING Book a time → https://cal.com/brogan-pratt-a4gcx7 ⚙️ Hardware: The Best PETG Filament: https://amzn.to/4mnNloY The Best PLA Filament: https://amzn.to/3SmRuf9 As an Amazon Associate I earn from qualifying purchases. 📚 Chapters: 0:00 Intro 0:52 Scale Model 2:50 How a 4-Bar Linkage Works 5:15 Why Use a 4-Bar? 7:41 Demo
