Best of - The future of robot simulations

Hi everyone, Russ here, we’re running a best-of episode this week to re-share a conversation I had in 2021 with Karen Liu, an associate professor of computer science here at Stanford Engineering. The conversation is relevant today because, as we all know, AI is having a moment, and robotics is an important part of that. Karen and her lab have a goal of enabling robots to contribute in caregiving roles - think of tasks like helping medical patients get dressed each day - and they’re using physics-based simulations to do that. I hope you’ll take some time to tune into this discussion, it’s a timely and relevant one given larger societal conversations about AI.
