Chelsea Finn: This is the State of the Art in Robotics
Chelsea Finn discusses advancements in physical intelligence, highlighting the development of general-purpose robots capable of performing various tasks autonomously. Key techniques include reinforcement learning, efficient data utilization, and the importance of memory in complex task execution.
Summary
In her presentation, Chelsea Finn explores the state-of-the-art in robotics, specifically focusing on physical intelligence and the evolution of robots capable of completing tasks autonomously in real-world environments. She emphasizes the progress made in developing general-purpose robots, which can take on various tasks without prior exposure, illustrating improvements in practical applications like making espresso, folding clothes, and performing complex workflows. Finn outlines the significance of long-term autonomy for these robots, requiring high reliability and the ability to learn from mistakes. She introduces a novel approach of using reinforcement learning combined with human intervention to enhance learning efficiency and improve task performance.
Furthermore, Finn highlights the value of memory in robotics, enabling robots to track progress across long tasks that require multiple steps. She discusses the development of a unified model (the PIO7 model) that can generalize across tasks without requiring extensive fine-tuning, showcasing signs of compositional generalization where robots can apply learned skills to new objects and tasks. This model's performance has been benchmarked against specialized models and has shown comparable or superior outcomes. Finn concludes by discussing the future of robotics and the need for diverse data sets to ensure effective learning, stressing the potential for democratizing general-purpose robotics through open-source technologies.

[0:06] Everyone, today I'm going to be talking about the state-of-the-art of physical intelligence. And in particular, two years ago, I founded a company called physical intelligence. And uh we're really interested in how we can basically uh develop any robot allow any robot to do any task in the real world. Uh and I was actually spoke at this event a year ago uh last year and at the event last year [0:37] I shared some of our progress in uh at the company at physical intelligence where we could do things really complicated tasks like uh folding unloading and folding laundry. Uh, and we I also talked about how for the first time we showed how robots can…

A camera that can see through walls
Bill Abster from Applied Electromagnetics discusses his company's breakthrough technology that uses radio waves and high-frequency antennas to create 3D images of objects behind opaque materials. The system processes echoes in real-time using GPUs to generate detailed depth maps, and the company has achieved significant progress in just 4 months by maintaining rapid iteration cycles.
What If We Stopped Using GPUs? | YC Paper Club
A YC Paper Club discussion exploring alternatives to GPU-based computing, featuring presentations on optical computing, neuromorphic chips, and biological computing approaches. Speakers argue that GPU efficiency (FLOPS per joule) has plateaued, necessitating fundamentally different computational substrates inspired by the brain's 20-watt energy efficiency.
Robotic factories that build robots
Tensor is building a 12,000 sq ft robotic factory that manufactures robots, including humanoids and specialized grippers. The company, founded by Berkeley researchers with autonomous vehicle and manufacturing backgrounds, treats the entire factory as a learning system that improves manufacturing processes with each customer order.
New LLMs Are Unlocking Robot-Use Agents
This discussion explores how large language models like Claude (Astra) are enabling robot control through code generation and tool use, building on foundational work like RT2 and visual language-action models. The speakers from Waddle Labs and RoboCurve explain how models trained on diverse data modalities—including web text, computer usage, and coding—are converging toward general-purpose robot agents that can perform complex physical tasks within the next 2 years.
Rocket cargo delivery anywhere on Earth in minutes
