Help understanding this mechanism
Hello all, I am trying to recreate this mechanism as a personal project - and I am really having trouble wrapping my head around how it works. The knees and below make perfect sense, but the hips are throwing me off. What is the purpose of the 2 perpendicular motors at the top? The ones facing horizontally? And how does the rest of the hip fit in with that purpose? I hope this question makes sense. Here is a research paper showing another angle and a more mechanical breakdown. https://arxiv.org/html/2512.16705v1#S4.F3 Also Nvidia GTC 2026 is where the original clip is from (2:11:36) further in the video it shows a side view: https://www.nvidia.com/gtc/keynote/ submitted by /u/halxcyion [link] [Kommentare] reddit.com · reddit.com
