Artificial intelligence (AI) has made significant strides in recent years, particularly in language modeling, protein folding, and gameplay. However, the progress of robot learning has been slower due to the challenges posed by sensorimotor behaviors and the complexity of software frameworks. This has hindered quick prototyping and the flow of ideas in the field of robotics, which is more fragmented compared to other AI disciplines like computer vision or natural language processing.
To address these challenges and bridge the gap in robot learning, researchers from reputable institutions such as U.Washington, UC Berkeley, CMU, UT Austin, Open AI, Google AI, and Meta-AI have developed RoboHive. RoboHive is an integrated environment specifically designed for robot learning, serving as both a benchmarking and research tool. It offers a wide range of contexts, specific task descriptions, and strict assessment criteria to enable various learning paradigms including reinforcement, imitation, and transfer learning. This allows researchers to efficiently investigate and prototype new ideas.
RoboHive also provides hardware integration and teleoperation capabilities, facilitating a seamless transition between real-world and virtual robots. The platform aims to close the gap between the current state of robot learning and its potential for further development. The creation and open-sourcing of RoboHive is a significant contribution to the field of robot learning.
RoboHive’s Key Features
1. The Environment Zoo: RoboHive offers various settings for manipulation tasks, including dexterity in-hand manipulation, movement with bipedal and quadrupedal robots, and musculoskeletal arm-hand models. It utilizes MuJoCo for quick physics simulation, ensuring physical realism.
2. Unifying RobotClass Abstraction: RoboHive provides a unifying RobotClass abstraction that enables smooth interaction with virtual and actual robots through simhooks and hardware hooks. Researchers can easily switch between simulation and reality by changing a single flag.
3. Teleoperation Support and Expert Dataset: RoboHive comes with out-of-the-box teleoperation capabilities using various modalities such as keyboards, 3D space mouse, and virtual reality controllers. It also offers the RoboSet dataset, which is one of the largest real-world manipulation datasets gathered through human teleoperation. This dataset is particularly useful for researchers working in imitation learning and offline learning.
4. Visual Diversity and Physics Fidelity: RoboHive emphasizes projects that prioritize physical realism and visual diversity. It includes complex assets, rich textures, and enhanced scene arrangements to closely simulate real-world visual challenges. The platform also allows for scene layout and visual domain randomization, enhancing visual perception’s adaptability and delivering realistic and rich physical material.
5. Metrics and Baselines: RoboHive utilizes clear and concise metrics to assess algorithm performance in various situations. It offers a user-friendly gym-like API for seamless integration with learning algorithms, making it accessible to researchers and practitioners. Additionally, RoboHive provides comprehensive baseline results for commonly researched algorithms, serving as a benchmark for performance comparison and study.
