Drumming seemed like a perfect frontier, as it&#8217;s rhythmic, physical, and requires rapid coordination across limbs.&#8221;<\/p>\n<p>Robot Drummer isn\u2019t a robot itself; rather, it&#8217;s a simulation that uses the G1 Unitree robot as a model to build a system that a future humanoid robot could eventually use. The 3-D visualised G1 robot plays a color-coded drum kit.<\/p>\n<p>In a video published on <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.youtube.com\/@TheRobotDrummer\" target=\"_blank\" data-url=\"https:\/\/www.youtube.com\/@TheRobotDrummer\" referrerpolicy=\"no-referrer-when-downgrade\" data-hl-processed=\"none\" rel=\"nofollow noopener\">YouTube<\/a>, Robot Drummer is shown mimicking the drum beats to two well-known songs. There&#8217;s something a little off about the sound \u2014 perhaps to make the drumming more accessible to the ear. Its rendition of \u201cIn the end\u201d, by Linkin Park sounds just off the rhythm, while its attempt at &#8220;Roxanne&#8221; by the Police sounds more matched to the rest of the arrangement.<\/p>\n<p>Related: <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.livescience.com\/technology\/robotics\/robots-awkwardly-race-fight-and-flop-around-in-chinas-first-world-humanoid-robot-games\" data-before-rewrite-localise=\"https:\/\/www.livescience.com\/technology\/robotics\/robots-awkwardly-race-fight-and-flop-around-in-chinas-first-world-humanoid-robot-games\" rel=\"nofollow noopener\" target=\"_blank\">Robots awkwardly race, fight and flop around in China&#8217;s first World Humanoid Robot Games<\/a><\/p>\n<p class=\"newsletter-form__strapline\">Get the world\u2019s most fascinating discoveries delivered straight to your inbox.<\/p>\n<p>Learning to play any musical instrument, particularly the drums, presents a unique challenge, the researchers said in the study. It is a multifaceted task that needs split-second timing, rapid contacts, and the combined coordination of hands and feet \u2014 all of which needs to be sustained for several minutes.<\/p>\n<p>Trial and error was the basis for Robot Drummer\u2019s learning, with the researchers employing reinforcement learning (RL), a type of <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.livescience.com\/technology\/artificial-intelligence\/what-is-artificial-intelligence-ai\" data-before-rewrite-localise=\"https:\/\/www.livescience.com\/technology\/artificial-intelligence\/what-is-artificial-intelligence-ai\" rel=\"nofollow noopener\" target=\"_blank\">artificial intelligence<\/a> (AI) machine learning process in which an agent learns to make decisions by interacting with its environment.<\/p>\n<p id=\"194b8c27-bbe2-4f35-ac7d-f51fbfe27e9d\">The agent is rewarded or punished for its actions with a mathematical signal, and it\u2019s often a positive number that signifies a correct action. The aim is to earn more rewards by finding the optimal policy. For Robot Drummer, each song was represented as a chain of precisely timed \u201ccontact events,\u201d according to the researchers, which informed the robot what drum strikes were needed and where.<\/p>\n<p>Learned behaviours, the researchers noted, included specific drumming strategies, such as cross-arm strikes and adaptive stick assignments (using a drum stick for a particular sound). This, the researchers said, demonstrated the potential of reinforcement learning for robots in creative domains such as music.<\/p>\n<p>The researchers said that Robot Drummer was put through extensive experiments with over 30 popular songs across pop, rock, metal, and jazz.<\/p>\n","protected":false},"excerpt":{"rendered":"In the End &#8211; Linkin Park &#8211; Robot Drum Cover &#8211; YouTube Watch On Humanoid robots can pick&hellip;\n","protected":false},"author":2,"featured_media":104427,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[45],"tags":[182,181,507,74],"class_list":["post-104426","post","type-post","status-publish","format-standard","has-post-thumbnail","category-artificial-intelligence","tag-ai","tag-artificial-intelligence","tag-artificialintelligence","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/104426","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=104426"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/104426\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/104427"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=104426"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=104426"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=104426"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
