Welcome to the Intelligent Robotics and Interactive Systems (IRIS) Lab at ASU. We study contact-rich physical intelligence: how robots learn to act through physical interaction with objects, environments, and humans. Our goal is to develop robots that can understand and exploit contact to achieve dexterity, robustness, and adaptability in the real world.

Below are selected demos from our lab. For more details, please see the Good Papers page.

ComFree: Scalable Contact Physics Engine

ComFree-Sim is our complementarity-free contact physics engine for contact-rich simulation. It computes contact dynamics analytically and scales efficiently with contact count, achieving over 5× higher throughput than MuJoCo Warp in dense-contact benchmarks.

Online (~100Hz) Optimization Through Contact

Our ComFree predictive control policy online plans contact-rich actions at 100 Hz, automatically deciding where, when, and how to make contact for diverse manipulation and locomotion tasks.

Efficient Learning of Contact-Rich Dexterity

By embedding contact-physics structure into learning, our methods reduce data needs by over 10× for contact-rich manipulation, enabling zero-shot sim2real transfer or learning directly on hardware within few minutes.

Pixel to Contact Physics (Real-to-Sim)

Our methods turn videos into simulation-ready physical engines (real2sim) for contact-rich manipulation, by jointly estimating contact geometry, pose, and physics properties from pixels.
