Unlocking Advanced Humanoid Interaction: InterReal's Breakthrough
InterReal presents a novel physics-based imitation learning framework designed to significantly enhance humanoid robots' ability to perform complex human-object interaction (HOI) tasks. By integrating motion data augmentation, a meta-policy-guided automatic reward learner, and a robust simulation-to-real-world deployment pipeline, InterReal addresses critical limitations of existing non-interactive control systems.
This framework not only achieves superior tracking accuracy and task success rates in challenging HOI scenarios but also demonstrates unprecedented robustness and adaptability in real-world environments, paving the way for autonomous humanoid applications in industry and beyond.

Motion Augmentation
InterReal introduces a novel HOI motion data augmentation scheme that uses inverse kinematics (IK) to generate multiple motions from a single anchor motion. This process varies object positions while preserving hand-object contact details, significantly improving the generalization ability of interactive policies and robustness to object perturbations.
- IK-based augmentation ensures hand-object contact consistency.
- Generates diverse training data by altering object positions (e.g., ∆x, ∆y offsets).
- Enhances policy generalization and robustness against real-world object perturbations.
Automatic Reward Learning
To overcome the challenges of large-scale reward shaping in DRL, InterReal proposes an automatic reward learner. A meta-policy, guided by critical tracking error metrics (e.g., joint position, object position, link position errors), dynamically explores and allocates reward signals to the low-level reinforcement learning objective. This adaptive approach improves motion tracking performance without tedious manual tuning of reward weights.
- Meta-policy dynamically balances reward terms based on tracking error metrics.
- Adapts reward weights to different motion phases.
- Eliminates the need for manual, heuristic reward shaping.
Asymmetric Actor-Critic
InterReal employs an asymmetric actor-critic module in its PPO architecture. The critic has access to perfect states (robot proprioception, gravity projection, interaction graph, object features), while the actor receives imperfect states, excluding interaction graph, object velocity, and rotation features. This design mitigates the sim-to-real gap and policy vulnerability caused by unstable real-world object features.
- Actor receives imperfect states, critic uses perfect states.
- Actor excludes unstable object velocity and rotation features.
- Reduces sim-to-real gap and improves policy robustness.

Real-World Deployment: Unitree G1 Robot
InterReal's policies were successfully deployed on the Unitree G1 humanoid robot in real-world scenarios. The system leverages FoundationPose for real-time object posture feedback, enabling the robot to dynamically adjust arm behavior and movement based on detected object positions. This demonstrates the framework's practical effectiveness and robustness beyond simulation, even under conditions like object position loss, delay, and perturbation.
- Validated on Unitree G1 with real-time object feedback.
- Adjusts arm behavior dynamically based on object positions.
- Robust against real-world challenges (position loss, delay, perturbation).
