Mapping real environments into aligned digital worlds enables replacing all real-world robotics data with scalable digital data, solving the key training and evaluation bottlenecks in general-purpose robotics.

Yinuo explains Scenix's real-to-sim-to-real pipeline: map physical environments into aligned digital worlds where training and evaluation data can be generated at scale, bypassing real-world constraints. ✦ AI generated

“So, Yinuo, you're the co-founder of Scenix. So, maybe provide everyone with a quick overview of your background and what Scenix does.”

So for cynics the unique opportunity we see is that there has been a lot of like a bottlenecks. Right now we see faced by the developments of general purpose robots especially around training and also around evaluations. So as we are developing what we call a real to sim to real pipeline. Okay. We want to map the real environments into the digital world that has the best alignments with the real environments. By alignments we mean that whatever happens in the digital world is also going to happen in the real environments such that we can replace all the data all the evaluation we need in the real environment by using the data that can generate at a scalable way in our digital world. So that is how everything started in Synex.

5:03started in Synex. We put together a very very strong and best teams around robotics, robot learning and also simulation and rendering trying to build this realtom real stack to solve some of the key bottlenecks. >> It's amazing that you two work together. >> Yeah. And uh there is a funny story here because you would think because we worked together he was my amazing postto we've been talking about this and world

They came into World Wars as a customer. >> Really? >> When we when we released the first version of our generative model called Marble last winter around uh November, December, >> Cynics just signed up. >> No kidding. AS A CUSTOMER. >> YES. [laughter] And I didn't even know what it was. And then I realized this is Vindrew's

The fundamental bottleneck in robotics is the lack of data for training and evaluation — unlike language models where data is abundant on the internet, robotics requires a real-to-sim-to-real pipeline to unlock scaling laws.Yunzhu Li · a16z Podcast · conf 80%

supports → The real-to-sim-to-real pipeline maps real environments into aligned digital worlds to replace costly real-world data collection with scalable simulation data for robotics training and evaluation.Yunzhu Li · a16z Podcast explains mechanism → The lack of data in training and evaluation is the most profound problem in robotics, fundamentally different from language models where data is abundant, and unlocking scaling laws for robotics depends on solving it.Fei-Fei Li · a16z Podcast supports → The unique bottleneck in general-purpose robotics is the lack of data for training and evaluation, which can be solved by a 'real-to-sim-to-real' pipeline that aligns digital worlds with physical environments so that simulation data replaces real-world data at scale.Yunzhu Li · a16z Podcast gives example → The next frontier of AI is spatial intelligence — creating AI that can generate, understand, reason with, and interact with physical or virtual spaces.Fei-Fei Li · a16z Podcast
