Whole-Body Model-Predictive Control of Legged Robots with MuJoCo

ICRA 2026poster

We demonstrate the surprising real-world effectiveness of a very simple approach to whole-body model- predictive control (MPC) of quadruped and humanoid robots: the iterative linear-quadratic regulator (iLQR) algorithm with MuJoCo dynamics and finite-difference approximated derivatives. Building upo…

ASAP: Aligning Simulation and Real-World Physics for Learning Agile Humanoid Whole-Body Skills

RSS 2025poster

Humanoid robots hold the potential for unparalleled versatility by performing human-like, whole-body skills. However, achieving agile and coordinated whole-body motions remains a significant challenge due to the dynamics mismatch between simulation and real-world physics. Existing approaches, such a…

Full-Order Sampling-Based MPC for Torque-Level Locomotion Control via Diffusion-Style Annealing

ICRA 2025

Due to high dimensionality and non-convexity, real-time optimal control using full-order dynamics models for legged robots is challenging. Therefore, Nonlinear Model Predictive Control (NMPC) approaches are often limited to reduced-order models or local approximations. Sampling-based MPC has shown p

Safe Bayesian Optimization for the Control of High-Dimensional Embodied Systems

CoRL 2024poster

Learning to move is a primary goal for animals and robots, where ensuring safety is often important when optimizing control policies on the embodied systems. For complex tasks such as the control of human or humanoid control, the high-dimensional parameter space adds complexity to the safe optimizat…
