The field of robotics has been working tirelessly to create increasingly sophisticated machines that possess dynamic locomotion capabilities similar to those of animals or humans. Google has been at the forefront of this pursuit, and recognizing the importance of accurately measuring robotic agility, they have recently introduced a revolutionary benchmark known as the Barkour Benchmark.
The Barkour agility benchmark for quadruped robots draws its inspiration from dog agility competitions, which showcase the speed, flexibility, and intelligence of our canine companions. To put these robotic creations to the test, the engineers at Google have designed a diverse and challenging obstacle course that pushes the machines to their limits.
In a unique twist, the involvement of dooglers – small dogs who work alongside their owners – has been integral to the development of the benchmark. These agile pups can complete the course in as little as 10 seconds, while a well-trained quadruped robot typically clocks in at a 20-second finish. Barkour’s scoring system is based on traditional dog agility competitions, ensuring a consistent and fair evaluation process.
The Barkour course is a compact 5m x 5m test environment, packed with four unique obstacles that demand a diverse set of skills from participating quadruped robots. The obstacles include weaving through a series of poles, climbing an A-frame ramp, clearing a 0.5m broad jump, and finally stepping onto an elevated end table. This gauntlet is designed to mimic the challenges faced by dogs in agility competitions, pushing the robots to demonstrate their maneuverability and precision.
To aid quadruped robots in their quest for agility, a Transformer-based generalist locomotion policy has been developed. This innovative technology allows the robots to handle complex tasks by sequentially chaining together simpler ones. Training the robots involves a domain-randomized curriculum, wherein various environmental and task parameters are continuously altered, ensuring that the machines are well-adapted to a wide range of conditions.
Results from the Barkour benchmark have exhibited a significant improvement in quadruped robot performance compared to prior methods. While the robots cannot yet match the speed of their canine counterparts, their ability to successfully navigate the course showcases the potential for vast improvements in the field of agile robotics.
In summary, the Barkour benchmark represents a pioneering innovation in the field of robotics, as it offers a comprehensive and standardized test of quadruped robot agility. This benchmark encourages the development of increasingly sophisticated and capable robots, pushing the boundaries of robotic mobility and maneuverability. As the Barkour benchmark continues to drive progress in agile robotics, we can anticipate extraordinary advancements within the field, unlocking new possibilities and applications for these remarkable machines.
Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.
Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).
This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.
I honestly can't wait to work in many more projects together!
