Welcome to the Safe Robotics Laboratory at Princeton!
Our lab is pioneering rigorous safety frameworks with clear-cut guarantees to make robots and AI truly trustworthy partners in everyday life.
Making robots and AI safe around people.
Our group develops theory and algorithms empowering robots, autonomous cars, and AI assistants to actively ensure safety in dynamic, unpredictable human environments.
We believe safety means more than a low probability of failure—it means knowing that our systems will anticipate and avoid hazards before they can cause harm.
Our research brings together control systems, game theory, and artificial intelligence to unlock rigorous safety guarantees that we can all understand and trust.

Kai-Chieh Hsu presented our new
Fast, Smooth, and Safe
paper in collaboration with Peter Ramadge's group at CDC 2023.
Our new method brings reach-avoid optimal control and CBFs under a unified lens
to systematically construct minimally conservative CBFs at runtime.
The best part: it works for arbitrary nonlinear systems without needing hand design.
