Open-H-Embodiment: A Large-Scale Dataset for Enabling Foundation Models in Medical Robotics
Autonomous medical robots are increasingly recognized for their potential to revolutionize healthcare by improving patient outcomes, reducing the workload of healthcare providers, democratizing access to care, and achieving superhuman precision in surgical procedures. However, the development of advanced autonomous medical robotics has been hampered by a significant data challenge. Existing datasets are often small, limited to single embodiments, and are rarely shared with the broader research community. This lack of comprehensive data restricts the advancement of foundation models essential for the field.
In response to this pressing issue, researchers have introduced Open-H-Embodiment, the largest open dataset of medical robotic video with synchronized kinematics to date. This groundbreaking dataset encompasses data from over 49 institutions and spans multiple robotic platforms, including:
- CMR Versius
- Intuitive Surgical’s da Vinci
- da Vinci Research Kit (dVRK)
- Rob Surgical BiTrack
- Virtual Incision’s MIRA
- Moon Surgical Maestro
- Various custom systems
The dataset covers a wide range of medical procedures, including surgical manipulation, robotic ultrasound, and endoscopy, thus providing a rich resource for researchers and developers in the field of medical robotics.
To illustrate the research potential unlocked by the Open-H-Embodiment dataset, two innovative foundation models have been developed. The first, GR00T-H, stands out as the first open foundation vision-language-action model tailored for medical robotics. Remarkably, it is the only evaluated model to have achieved full end-to-end task completion on a structured suturing benchmark, with a success rate of 25% across trials compared to 0% for all other models. Furthermore, GR00T-H demonstrates a 64% average success rate throughout a complex 29-step ex vivo suturing sequence.
The second model, Cosmos-H-Surgical-Simulator, represents a significant advancement in surgical simulation. This model is the first action-conditioned world model capable of enabling multi-embodiment surgical simulation from a single checkpoint. It spans nine robotic platforms and facilitates in silico policy evaluation as well as synthetic data generation specifically for the medical domain.
These groundbreaking results indicate that open, large-scale medical robot data collection can act as critical infrastructure for the research community. By democratizing access to comprehensive datasets, researchers can drive advances in robot learning and world modeling, ultimately paving the way for more sophisticated and capable medical robots.
As the field of medical robotics continues to evolve, the introduction of the Open-H-Embodiment dataset marks a pivotal moment. It not only enhances the ability to develop foundation models but also encourages collaboration and knowledge sharing within the research community. The implications for patient care and surgical precision are profound, offering a glimpse into a future where autonomous medical robots play an integral role in healthcare delivery.
