Unlike a mosquito that must constantly expend energy to stay aloft, a flea only works out when it jumps. Those cost savings could also pay off in the world of robotics: A group of small, simple hopping robots could explore a location much more cheaply than flying drones. These robots could find gas leaks in an oil refinery, monitor water and fertilizer usage on a farm, or even explore other planets.<\/p>\n<p>The new robot uses a tiny electric motor and three folding legs to launch itself to a specified jump height with single centimeter accuracy. After it lands, DirectHop can twitch to right itself and then ready for another jump.<\/p>\n<p>The prototype, which fits in the palm of a hand, represents multiple steps on the path to an autonomous hopping robot that can traverse a variety of environments.<\/p>\n<p>\u201cIn my mind, the three hardest challenges for hopping robots are the ability to vary jump length, self-right and reload for multiple hops,\u201d says senior author Sawyer Fuller, a\u00a0University of Washington associate professor of mechanical engineering.<\/p>\n<p>\u201cDirectHop clears all three of those hurdles with a totally new design, and we\u2019re well on our way to tackling other challenges like onboard power, steering and navigation.\u201d<\/p>\n<p>Most hopping robots are modeled after insects like fleas that are literally spring-loaded. Fleas compress and then release parts of their exoskeletons to launch themselves to distances 50 times their own height. Robots that utilize springs and latches \u00e0 la fleas can also travel impressive distances, but they have no easy way to calibrate jump distance\u2014discharging a spring is an \u201call or nothing\u201d action, says Fuller. What\u2019s more, springs and latches are complex bits of machinery that are difficult to build and operate at small scales.<\/p>\n<p>DirectHop\u2019s solution to those problems is ditching the spring entirely.<\/p>\n<p>\u201cWe found that a very small electric motor can accelerate fast enough to power a jump directly, the way a frog\u2019s leg muscles directly power its hop,\u201d says lead author Hanquan (John) Wang, a UW graduate research assistant in mechanical engineering. \u201cWe also discovered that by adjusting the current going to the motor, we could make the robot jump specific distances.\u201d<\/p>\n<p>The robot itself consists of a tiny electric motor attached to a tower by a length of fishing line. When the motor accelerates, it spools the line quickly and hoists itself up the tower, pulling the rest of the robot into the air. As the motor rises, three hinged legs extend to keep the motor aligned with the robot\u2019s foot.<\/p>\n<p>Since the robot tends to tumble in the air, the researchers included a roll cage to support it when it lands on its side. From there, the team was able to right it 90% of the time by sending the motor back down the tower, which shifts the robot\u2019s center of gravity and causes it to roll back onto its foot, readying it for another jump.<\/p>\n<p>The design was inspired by box turtles, which can roll themselves upright using a similarly-shaped shell.<\/p>\n<p>The current prototype has some notable limitations. Power is supplied via wires, and it has no way to steer or orient itself beyond random twitching. Wang and Fuller, however, are working on solutions: onboard solar cells and a battery for power, a vibration motor to spin the robot in place, tiny retractable feet to adjust hop angle, and an onboard camera and electronics to navigate.<\/p>\n<p>\u201cOne of our goals is fully autonomous stair climbing,\u201d Fuller says. \u201cA camera looks at the stair, the processor figures out how high the robot has to jump, it steers itself into position, jumps, self-rights, steers again, and repeats. It uses a combination of simple sensors and actions to perform a complex task.\u201d<\/p>\n<p>Wang thinks it\u2019s reasonable to imagine producing a fully featured DirectHop bot for about $10 since the individual components are so small and cheap. At that price, the bots could be extremely useful as a semidisposable complement to larger, more capable, more expensive robots.<\/p>\n<p>\u201cWe could dispatch 100 or even 1,000 of these robots into the field,\u201d Wang says. \u201cIf some are lost or disabled, it\u2019s not really a failure. The team of them can complete the task.\u201d<\/p>\n<p>Fuller and his team presented DirectHop at the International Conference on Intelligent Robots and Systems. <a href=\"https:\/\/faculty.washington.edu\/minster\/files\/wang_talwekar_fuller_directhop_iros2026.pdf?_gl=1*10ycnuw*_ga*MTA4NDc2NzMxMC4xNzg0MzAwMDg3*_ga_3T65WK0BM8*czE3OTA3OTUyNTIkbzkkZzEkdDE3OTA3OTUyNjEkajUxJGwwJGgw*_gcl_au*ODY3NTI1NTE1LjE3ODQzMDAwODYuLS4tLjE3ODQzMDAwODYuNjkzMzEzMTMyLjE3OTA3OTUyNTYuMTc5MDc5NTI1Ng..*_ga_JLHM9WH4JV*czE3OTA3OTUyNTIkbzI1NCRnMSR0MTc5MDc5NTI2MSRqNTEkbDAkaDA.\">Read the paper<\/a>.<\/p>\n<p>This research was funded by the National Science Foundation.<\/p>\n<p><em>Source: <a href=\"https:\/\/www.washington.edu\/news\/2026\/09\/23\/directhop-hopping-robot\/\">University of Washington<\/a><\/em><\/p>\n<p>The post <a href=\"https:\/\/www.futurity.org\/tiny-jumping-robot-directhop-3348042\/\">Tiny robot can precisely control how high it jumps<\/a> appeared first on <a href=\"https:\/\/www.futurity.org\/\">Futurity<\/a>.<\/p><div id=\"dev95-1008478139\" class=\"dev95- dev95-entity-placement\"><center>\r\n<script>\r\n  atOptions = {\r\n    'key' : '4ba6b6513c00e0ba76511f798ae56401',\r\n    'format' : 'iframe',\r\n    'height' : 50,\r\n    'width' : 320,\r\n    'params' : {}\r\n  };\r\n<\/script>\r\n<script src=\"https:\/\/www.highrevenueformat.com\/4ba6b6513c00e0ba76511f798ae56401\/invoke.js\"><\/script>\r\n\t<\/center><\/div>\n<\/div>\n<p style=\"margin-top: 20px\">\n    <strong>Read the full original article here:<\/strong><br \/>\n    <a href=\"https:\/\/www.futurity.org\/tiny-jumping-robot-directhop-3348042\/?utm_source=rss&#038;utm_medium=rss&#038;utm_campaign=tiny-jumping-robot-directhop-3348042\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Original source<\/a>\n<\/p>\n<div class=\"pvc_clear\"><\/div>\n<p id=\"pvc_stats_12835\" class=\"pvc_stats total_only  \" data-element-id=\"12835\" style=\"\"><i class=\"pvc-stats-icon large\" aria-hidden=\"true\"><svg aria-hidden=\"true\" focusable=\"false\" data-prefix=\"far\" data-icon=\"chart-bar\" role=\"img\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 512 512\" class=\"svg-inline--fa fa-chart-bar fa-w-16 fa-2x\"><path fill=\"currentColor\" d=\"M396.8 352h22.4c6.4 0 12.8-6.4 12.8-12.8V108.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v230.4c0 6.4 6.4 12.8 12.8 12.8zm-192 0h22.4c6.4 0 12.8-6.4 12.8-12.8V140.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v198.4c0 6.4 6.4 12.8 12.8 12.8zm96 0h22.4c6.4 0 12.8-6.4 12.8-12.8V204.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v134.4c0 6.4 6.4 12.8 12.8 12.8zM496 400H48V80c0-8.84-7.16-16-16-16H16C7.16 64 0 71.16 0 80v336c0 17.67 14.33 32 32 32h464c8.84 0 16-7.16 16-16v-16c0-8.84-7.16-16-16-16zm-387.2-48h22.4c6.4 0 12.8-6.4 12.8-12.8v-70.4c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v70.4c0 6.4 6.4 12.8 12.8 12.8z\" class=\"\"><\/path><\/svg><\/i> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"16\" height=\"16\" alt=\"Loading\" src=\"https:\/\/i0.wp.com\/dev95.site\/wp-content\/plugins\/page-views-count\/ajax-loader-2x.gif?resize=16%2C16&#038;ssl=1\" border=0 \/><\/p>\n<div class=\"pvc_clear\"><\/div>\n<div id=\"dev95-3752196291\" class=\"dev95-after-content dev95-entity-placement\"><p style=\"text-align: center;\"><strong>Finally, a link that actually works for your region and device! \ud83c\udf0d Get instant access to the top exclusive offers tailored just for you right now.
