Robots Get Their Homework: The Emergence of Autonomous Skill Improvement

In a groundbreaking development, researchers have unveiled an algorithm that empowers robots to identify and address their own skill deficiencies, subsequently dedicating focused practice sessions to enhance overall performance. Dubbed the 'Estimate, Extrapolate, and Situate' (EES) algorithm, this innovation marks a significant leap towards self-sufficient machines capable of learning and refining their abilities in various settings, from factories to hospitals. The EES algorithm, presented at the Robotics: Science and Systems conference by the MIT Computer Science and Artificial Intelligence Lab (CSAIL) and The AI Institute, operates by first evaluating the robot's surroundings and the task at hand, such as tidying a room. It then estimates the robot's current competency in executing specific actions, like wielding a broom for sweeping. If EES detects potential for improvement in a particular skill, it initiates targeted practice sessions.During testing, the researchers implemented EES on Boston Dynamics' Spot quadruped robot, which has demonstrated remarkable aptitude in tasks involving arm attachments. Utilizing the algorithm, Spot not only maintained its high-performance standards but also honed its skills more efficiently. For instance, EES enabled Spot to master the secure placement of a ball and ring on a slanted table in roughly three hours, a feat that would have likely required over 10 hours using previous frameworks. While the tasks performed by Spot were relatively basic, the researchers emphasize the potential of this technology to produce robots capable of learning and enhancing their performance in diverse environments. Future plans include the integration of simulators for combined virtual and physical practice sessions, as well as the development of algorithms that can reason over sequences of practice attempts rather than focusing solely on isolated skills. Danfei Xu, a Georgia Tech professor and research scientist at Nvidia AI, expressed enthusiasm for the potential of self-learning robots: 'Enabling robots to learn on their own is both incredibly useful and extremely challenging. . . it's essential that they can learn on the job. ' With the EES algorithm paving the way, robots may soon master new skills as effortlessly as humans – through the time through the time-hon
