| | ### Dataset Summary |
| |
|
| | **DreamerBench** is a large-scale dataset designed for training and evaluating **World Models** in robotics applications. Unlike standard visual-only datasets, DreamerBench explicitly focuses on physical interaction dynamics, specifically **friction** and **contact data**. |
| |
|
| | The dataset is generated using Project Chrono (https://projectchrono.org/), simulating diverse robotic interaction scenarios where precise modeling of physical forces is critical. It includes pre-computed **encodings** to facilitate efficient training of latent dynamics models. |
| |
|
| | Key features: |
| | * **Physical Fidelity:** detailed ground-truth annotations for coefficient of friction, contact forces, and slip. |
| | * **Multi-Modal:** Contains visual observations (RGB/Depth), proprioceptive states, and explicit physics parameters. |
| | * **World Model Ready:** Structured to support next-step prediction and imaginary rollout training (Dreamer-style architectures). |
| |
|
| | ### Supported Tasks and Leaderboards |
| |
|
| | * **World Modeling / Dynamics Learning:** Training models to predict future states ($s_{t+1}$) given current state ($s_t$) and action ($a_t$). |
| | * **Offline Reinforcement Learning:** Learning policies from the provided simulator trajectories without active environmental interaction. |
| | * **Sim-to-Real Adaptation:** Using the varied friction/contact parameters to train robust policies that generalize to real-world physics. |
| | |
| | ## Dataset Structure |
| | |
| | ### Data Instances |
| | |
| | Each instance in the dataset represents a **trajectory** or **episode** of a robot interacting with the environment. |
| | |
| | **Example structure (JSON/Parquet format):** |
| | |
| | ```json |
| | { |
| | "episode_id": "traj_001", |
| | "steps": 1000, |
| | "observations": { |
| | "rgb": [Array of (1000, 64, 64, 3) images], |
| | "depth": [Array of (1000, 64, 64, 1) images], |
| | "proprioception": [Array of joint angles/velocities] |
| | }, |
| | "actions": [Array of control inputs], |
| | "rewards": [Array of float scalars], |
| | "physics_data": { |
| | "contact_forces": [Array of 3D force vectors], |
| | "friction_coefficient": 0.8, |
| | "contact_detected": [Binary array] |
| | }, |
| | "encoding": [Pre-computed latent vectors, e.g., VAE or RSSM states] |
| | } |
| | ``` |
