Can ordinary people build their own robots? Spending two weekends and over $2,000, we built a six-axis robotic arm from scratch! This video documents the entire process of creating the AR4-MK3 robotic arm from a pile of parts to a complete product: from 3D printing custom parts and complex wiring assembly to programming, debugging, and functional testing, every step was full of challenges and surprises. Ultimately, this robotic arm can not only easily grasp objects but also achieve professional-grade surround-view photography effects. Want to see how cool a homemade robotic arm is?
