Ego-Vision World Model for Humanoid Contact Planning
This paper presents a novel framework for humanoid robots to achieve agile, robust, and real-time contact planning using an ego-vision world model and value-guided sampling MPC. It leverages offline, demonstration-free data to predict future outcomes in a compressed latent space, addressing challenges like sparse contact rewards and sensor noise with a learned surrogate value function. The system demonstrates improved sample efficiency and multi-task capability on a physical humanoid robot for tasks like wall support, object blocking, and arch traversal, using ego-centric depth images and proprioception.

Real-World Deployment: Unitree G1 Humanoid
Our framework was successfully deployed on the Unitree G1 humanoid robot, demonstrating robust real-time contact planning capabilities. The robot performed complex tasks using only ego-centric depth images and proprioceptive feedback. This validates the system's ability to operate in challenging, unstructured environments.
Highlights:
- Support the Wall: Robot resists external disturbances via supportive hand contact.
- Block the Ball: Intercepts flying objects with defensive hand contact.
- Traverse the Arch: Passes through low-clearance arch avoiding head contact.
- Generalizes to out-of-distribution (OOD) scenarios (e.g., unseen box).
Impact of Planning Horizon (N)
Our analysis showed that a planning horizon of N=4 steps strikes a bias-variance sweet spot. Longer horizons (e.g., N=6) degrade performance due to bias dominating from longer-term prediction, while N=1 is infeasible as it makes the robot myopic and ignores future contacts. This empirically determined optimal horizon is crucial for robust performance.
