Batteries, even the smallest ones, weigh too much to make insect-scale flight viable. UC Berkeley\u2019s solution bypassed power storage entirely, leaning instead on wireless energy input. By offloading the power source to an external magnetic field, the team opened up a range of possibilities that bulky batteries would have shut down im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>tely. The result is a fully wireless micro-robot that can hover in place, dart to a target, or navigate tight, cluttered spaces.<\/p>\n<p>It\u2019s hard not to smile at how closely this robot mirrors its biological inspiration. Like bees pollinating flowers, the micro-robot can be directed to bump into tiny targets with surprising precision \u2014 a skill that could be vital for delicate tasks like artificial pollination, environmental monitoring, or navigating wreckage during search-and-rescue missions. It may not yet have the onboard intelligence of its insect cousins, but its ability to move and interact with its environment at this scale is impressive in its own right.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-543483\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_3.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_3.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-543483\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_3.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_3.jpg\"><\/p>\n<p>At 0.9 centimeters in diameter, it\u2019s more than three times smaller than the next closest competitor in the flying micro-robot category. That size advantage isn\u2019t just for show. Being this compact means the robot could access confined environments that larger robots simply can\u2019t \u2014 ventilation shafts, collapsed buildings, pipe systems, or even inside machinery. However, the current model still leans heavily on the strength of its external magnetic field, which means it\u2019s mostly a lab-bound curiosity for now. Strong fields are easy to generate in controlled settings but could prove tricky in unpredictable environments.<\/p>\n<p>The researchers are already dreaming up ways to make it even smaller, aiming for sub-millimeter sizes where weaker electromagnetic fields \u2014 or even radio waves \u2014 might be enough to keep them aloft. Pair that with swarm behavior, and you\u2019re looking at a future where hundreds of these robots could coordinate like ants or bees, performing complex tasks collectively rather than relying on individual strength or intelligence.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-543484\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_4.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_4.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-543484\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_4.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_4.jpg\"><\/p>\n<div class=\"code-block code-block-2\" style=\"margin: 8px 0; clear: both;\">\n<div style=\"padding: 4px; margin: 18px auto 20px; text-align:center;\"><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-7222236028814181\" crossorigin=\"anonymous\" type=\"e086463558301aad301d80de-text\/javascript\"><\/script><br \/>\n<!-- In-Content-Ads-2 --><\/p>\n<p><script type=\"e086463558301aad301d80de-text\/javascript\">\n<\/script><\/div>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-543485\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_5.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_5.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-543485\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_5.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_5.jpg\"><\/p>\n<p>It\u2019s also worth noting that this isn\u2019t UC Berkeley\u2019s first foray into biomimicry. The same team has played around with cockroach-inspired bots that can scurry under obstacles and even withstand being stepped on, as well as cooperative micro-robots that can link up like swarming insects. What\u2019s striking about this latest project, though, is how simple it is \u2014 no sensors, no wires, no batteries, just the clever use of magnets and motion.<\/p>\n<p>I can\u2019t help but think back to when we featured MIT\u2019s insect-sized winged drones, which stretched the limits of battery-powered flight to a then-astonishing 17 minutes. But what UC Berkeley shows here is a different kind of ambition \u2014 not about how long you can fly, but about how elegantly you can do it by ditching the traditional components that hold you back (like the battery, for instance). In a way, this tiny magnetic robot doesn\u2019t just imitate nature, it respects it \u2014 reminding us that sometimes, the smallest solutions carry the biggest potential.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-543486\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_6.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_6.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-543486\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_6.jpg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/03\/31\/uc-berkeley-unveils-worlds-tiniest-battery-free-drone-powered-by-magnetic-fields\/\" data-jpibfi-post-title=\"UC Berkeley Unveils World\u2019s Tiniest Battery-Free Drone Powered by Magnetic Fields\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/03\/worlds-smallest-drone-can-fly-without-batteries-drawing-power-from-magnetic-fields\/ucberkeley_worlds_smallest_drone_6.jpg\"><\/p>\n<div class=\"sharedaddy sd-sharing-enabled\">\n<div class=\"robots-nocontent sd-block sd-social sd-social-icon-text sd-sharing\">\n<h3 class=\"sd-title\"><span class=\"ez-toc-section\" id=\"SHARE\"><\/span>SHARE<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"sd-content\">\n<ul>\n<li class=\"share-facebook\"><span>Facebook<\/span><\/li>\n<li class=\"share-x\"><span>X<\/span><\/li>\n<li class=\"share-pinterest\"><span>Pinterest<\/span><\/li>\n<li class=\"share-reddit\"><span>Reddit<\/span><\/li>\n<li class=\"share-linkedin\"><span>LinkedIn<\/span><\/li>\n<li class=\"share-tumblr\"><span>Tumblr<\/span><\/li>\n<li class=\"share-pocket\"><span>Pocket<\/span><\/li>\n<li class=\"share-email\"><span>Email<\/span><\/li>\n<li class=\"share-print\"><span>Print<\/span><\/li>\n<li><a rel=\"nofollow\" target=\"_blank\" href=\"#\" class=\"sharing-anchor sd-button share-more\"><span>More<\/span><\/a><\/li>\n<li class=\"share-end\"><\/ul>\n<div class=\"sharing-hidden\">\n<div class=\"inner\" style=\"display: none;\">\n<ul>\n<li class=\"share-telegram\"><span>Telegram<\/span><\/li>\n<li class=\"share-threads\"><span>Threads<\/span><\/li>\n<li class=\"share-jetpack-whatsapp\"><span>WhatsApp<\/span><\/li>\n<li class=\"share-mastodon\"><span>Mastodon<\/span><\/li>\n<li class=\"share-bluesky\"><span>Bluesky<\/span><\/li>\n<li class=\"share-nextdoor\"><span>Nextdoor<\/span><\/li>\n<li class=\"share-end\"><\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- CONTENT END 1 --><\/p>\n<div>\n                                                            <\/div>\n<\/p><\/div>\n<p><span class=\"vcard author\"><br \/>\n                            <span>By<\/span><\/p>\n<p>                                <span>Sarang Sheth<\/span><\/p>\n<p>                        <\/span><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
