Google DeepMind introduces the Open X-Embodiment Dataset and RT-X Model
Robots are traditionally known for their specialized skillset rather than being generalists. The challenge has always been that any slight alteration in a task, robot, or environment necessitates starting over with training. Recognizing this, Google DeepMind has introduced resources for universal robotic learning. Collaborating with 33 academic labs, data from 22 robot variations was consolidated to produce the Open X-Embodiment dataset. Additionally, they launched the RT-1-X, a robotics transformer model displaying skill transference across numerous robot embodiments.
The core of their research reveals that when one model is trained using data from multiple embodiments, its performance outshines those models trained on singular embodiments. The RT-1-X model, when put to test in five distinct research labs, displayed a 50% average success rate boost across five commonly-used robots in contrast to those specifically engineered for each robot. Furthermore, when the visual language action model, RT-2, was trained using multi-embodiment data, its real-world robotic skills performance tripled.
Their endeavor is to drive forward cross-embodiment studies within the realm of robotics. The Open X-Embodiment dataset and RT-1-X model checkpoint are now open to the broader research community, courtesy of global robotics labs that shared their data. This move is anticipated to revolutionize robot training methods and fast-track research in this sector. It is their assertion that just as ImageNet advanced computer vision research, the Open X-Embodiment dataset holds the potential to be equally transformative for robotics. The dataset, arguably the most comprehensive of its type, showcases over 500 skills and 150,000 tasks, derived from over 1 million episodes across 22 robot embodiments.
RT-X stands as a landmark general-purpose robotics model. By drawing upon their previous models and training on the Open X-Embodiment dataset, RT-1-X and RT-2-X have displayed superior performance, better specialization, and newfound capabilities. In side-by-side comparisons with models designed for specific tasks, RT-1-X surpassed the competition by an average of 50%. Furthermore, RT-2-X has revealed a deeper spatial understanding, effectively differentiating and performing tasks based on subtle linguistic differences, proving that a high-capacity architecture and combined data from multiple robots can vastly expand a robot's skillset.
Robotics is on the precipice of groundbreaking discoveries. Through global collaboration and resource sharing, the research community is poised to make strides in open and responsible ways. The key lies in robots and researchers learning collectively. As evident from their latest innovations, models capable of generalizing across multiple embodiments aren't just a dream; they're a reality. As Google look aheads, the aim is to delve deeper into how varied dataset combinations can impact cross-embodiment generalization and the manifestation of enhanced generalization.
