Research Interests

I believe that computational modeling of physics and scene understanding is key to developing robots with genuine physical understanding. Most of my research begins with: building real robots, developing perceptual systems that interpret the world, simulating their dynamics, and controlling them in the wild.

A 2D physics simulation summarizing my research on legged robot, quadrotor, and perception. GRF & Gait cylce optimization is done at runtime. Feel free to turn the knob!

Representative papers are highlighted. (Equal contributions are denoted by *.)
