Artificial intelligence has captivated the world since the release of ChatGPT, enabling us to interact with AI tools more directly than ever before. Despite this progress, interacting with robots in our daily lives remains a rarity. However, experts are optimistic that this will soon change. Roboticists believe that by harnessing new AI techniques, they can develop robots that are more capable of navigating unfamiliar environments and overcoming unprecedented challenges.
Russ Tedrake, vice president of robotics research at the Toyota Research Institute, describes the current pace in robotics as being comparable to riding on the front of a rocket. While there have been previous cycles of hype and anticipation in the field, Tedrake asserts that the current advancements are unparalleled.
However, the progress of robotics is hindered by a lack of access to the necessary data for training robots to interact seamlessly with the physical world. Unlike the abundant availability of data used to train advanced AI models like GPT, physical world data is scarce and requires considerable time, effort, and expensive equipment to collect. The scarcity of this data is a significant obstacle in the development of robotics.
Consequently, leading companies and research labs are engaged in fierce competition to discover innovative approaches to gather the data they need. This pursuit has led them down unconventional paths, such as using robotic arms to flip pancakes endlessly, analyzing hours of graphic surgery videos sourced from YouTube, and even sending researchers to film various Airbnbs to capture every detail. Nevertheless, these endeavors raise similar concerns regarding privacy, ethics, and copyright as those encountered in the realm of chatbots.
Previously, robots were trained on specific tasks using equations and code, limiting their ability to transfer skills from one task to another. Now, with advancements in AI, robots can teach themselves through data, similar to language models learning from a library of novels. By demonstrating tasks to robot models, they can imitate the actions without explicit instruction.
The key challenge lies in finding diverse types of data to fine-tune robot models and employing reinforcement learning to determine correct actions. Determining the next significant data source has become a priority for many researchers and companies, as it will define the capabilities and potential roles of future machines.
Efforts to acquire data for robots resemble shopping at a butcher shop, with prime cuts, everyday staples, and trimmings that require creativity to transform. For instance, the Toyota Research Institute uses teleoperation to teach robots new tasks, generating demonstration data through the precise manipulation of robotic arms. However, creating this data is time-consuming and limited by cost.
To overcome these challenges, Shuran Song, head of the Robotics and Embodied AI Lab at Stanford University, designed a cost-effective device that facilitates data collection during everyday activities like cracking an egg or setting the table. This lightweight plastic gripper provides an efficient way to train robots to mimic human tasks, expediting the data gathering process.
Open-source initiatives have also emerged to facilitate collaboration and knowledge sharing in the robotics community. These efforts aim to accelerate progress and overcome the data scarcity challenge collectively.
As the pursuit of data for robotics continues, the field is poised for groundbreaking advancements. The ability to train robots using diverse data sources will unlock their potential, revolutionizing their role in our homes and workplaces.
