A newly developed bipedal golem can seamlessly trade between walking and flying , and it ’s the combination of these two accomplishment that really sets this futuristic car apart .
Introducing LEONARDO , or LEO for short . The name is an acronym for LEgs ONboARD drone , which nicely but insufficiently draw this robot . The Caltech locomotive engineer who construct LEO did n’t just slap a pair of robotlike legs onto an aerial trailer — they had to design the bot with both walking and flying in judgment and develop specialized software to integrates its various ingredient .
LEO is still a prototype — a sort of proof - of - concept to see if a bipedal flying robot can perform chore that would otherwise be difficult or unimaginable for ground robots or aeriform drones to carry out on their own . In the futurity , a full - fledged rendering could be tasked with unmanageable or dangerous jobs , such as inspecting and repairing damage base , install young equipment in unvoiced - to - hit berth , or attending to natural disasters and industrial accidents . finally , a LEO - like golem could even send delicate equipment to the surface of a celestial body , such as Mars or Saturn ’s moon Titan . More ominously , the quick bipedal flier could be used in defence or warfare .

LEO ’s sci - fi attributes are not an chance event . In an e-mail , the team tell me they were cheer by the fictional flying humanoid robotAstro Boyand the Iron Man - likejet suitsbuilt by Gravity Industries ’ Richard Browning . at long last , however , the intent of the project was to study the convergence of walking and flying from a moral force and control condition perspective and to “ give unprecedented walk power and to solve problems posed by hybrid motivity , ” as the team explained in a video . The Caltech is squad is also hope to construct adaptative landing gear for vertical take - off and landing ( VTOL ) on difficult terrain .
Nature figured out this trick long ago , as boo , bat , insects , and many other organism can change over back and forth between these two modes of travel . It provides a discrete evolutionary advantage . Robots , on the other handwriting , tend to be specialised and capable of moving in only one of these two ways . There are plus and negative to this : Ground robots are sure - footed , sturdy , and subject of carrying hard loads , but they sputter in hard terrain and can not reach high spot . ethereal dawdler are highly roving and capable of fly in all sorts of environments , but they ca n’t remain aloft for long due to the high push demand of flight , and they ’re bad at performing fine handling tasks . Hence the desire to create a machine that can leverage the good of both worlds .
To achieve balance on the ground and agility in the melody , LEO had to be carefully designed . Kyunam Kim , Soon - Jo Chung , Elena - Sorina Lupu , and Patrick Spieler explain in an electronic mail that this required sturdy but lightweight element , as well as algorithmic program for see to it LEO ’s four propellers and leg joints “ in a synchronal way to insure that LEO walks or flies without miss its balance . ” The two disparate domains “ are not typically twine in existing robotic systems , and we had to harness a plentiful set of engineering science trouble that were not well - study in other robotic organization , ” they add . A researchpaperoutlining this work was published today in Science Robotics .

LEO count just 5.7 pounds ( 2.58 kilo ) and stands 2.5 foundation ( 75 centimeter ) tall . Like a bird , the automaton uses its slender , multi - jointed legs to push off the earth and provide an help during lampoon . LEO ’s tilted galvanising pusher — the four propeller — are synched to these parachuting . LEO walks as if on high heels , but these heels allow for balanced standing ; should the conditions justify , however , LEO ’s propellers could always quetch in to ensure further constancy . shelling , sensors , and the required processing power are pack into the robot ’s body , allow for full autonomy and no clunky wires .
“ We take note that the optimization of LEO ’s energy ingestion was not a precedence in this work , ” the squad explained in its email . “ Instead we focused on a all-embracing reach of capability . ”
In trial run , LEO moved back and forth between nimble walking and flight of stairs , which it did to avoid gainsay obstacles and to perform difficult tasks in which Libra was postulate — including skateboarding and walking on a slackline . LEO ’s design enable “ dynamical bipedal walk with complex ground interaction , while keep up the flight execution of a multi - rotor vehicle , ” as the team indite in their email . The squad claims that LEO is the first biped robot to perform slacklining , albeit with avail from its propellers .
With the aggregate power of walk and flight , the squad hopes to enable a all-encompassing range of robotic commission , such as high - emf melodic phrase review and the monitoring of marvellous bridges . These bots could scrutinise aging infrastructure , work in cataclysm scenarios , and even explore removed worlds .
indite in an associated Focus article , Stefano Mintchev , a investigator at ETH Zurich ’s Department of Environmental Systems Science , say LEO ’s power need deal - offs :
The propeller are careen to be more effective in stabilizing LEO ’s walking , but this selection reduces their efficiency during escape . To minimize the weighting that needs to be lift , the leg are slender and underpowered . LEO involve ceaseless documentation from the propellers during take the air , which pretend it more energy hungry than a purely mundane golem would be … [The ] extent of these trade - offs , and thus how close a multimodal golem is to a purely terrestrial or aerial robot , is reliant on design choice . Minimizing patronage - offs remains a daunting challenge .
Mintchev , who was n’t involved in the fresh written report , offered his advice to the squad , saying they should keep being revolutionize by nature . He point to flying Snake , who flatten their bodies to meliorate gliding .
For sure , there ’s room for improvement , but LEO is the first of an whole new breed of robot . With Astro Boy being a key inspiration , these scientist still have a foresightful direction to go .
