The robot must react and intercept a potentially flying ball, using various maneuvers in very short time intervals, usually less than one second,&#8221; the study says.<\/p>\n<\/blockquote>\n<p>The device is capable of three main movements: a lateral shift, a jump, and a dive. By the latter, the researchers mean a sharp move to the side followed by a fall to intercept a ball flying to the bottom corner of the goal.<\/p>\n<p>Mini Cheetah analyzes the object&#8217;s position using a depth camera, after which the AI algorithm selects an appropriate trajectory for the robot&#8217;s joints, enabling interception of the ball, and the low-level controller computes the corresponding torques for the motors to realise the required movements.<\/p>\n<p>Initially the robot was trained to defend the goal in Nvidia&#8217;s Isaac Gym simulator. The platform enables reinforcement learning in a virtual space that mimics physical interactions.<\/p>\n<p>Researchers subsequently transferred the obtained skills to the real Mini Cheetah and tested its effectiveness in a game of football against a human and another robot. As a result, the device successfully blocked balls, taking 0.9 seconds to perform the movements.<\/p>\n<p>According to the researchers, the technology could be used to train a robot to play football in the role of a forward.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;We focused exclusively on the task of creating a goalkeeper, but the proposed framework can be extended to other scenarios, including taking shots at the ball,&#8221; the study notes.<\/p>\n<\/blockquote>\n<p>In October, a team of engineers developed a system of algorithms enabling robodogs to move in the wild.
