The name makes it sound like a drone with legs, but it has a somewhat humanoid shape, with multi-joint legs, propeller thrusters that look like arms, a \u201cbody\u201d that contains its motors and electronics, and a dome-shaped protection helmet.<\/p>\n\n\n\n<p>Leo was built by a team at Caltech, and they were particularly interested in how the robot would transition between walking and flying. The team notes that they studied the way birds use their legs to generate thrust when they take off, and applied similar principles to the robot. In a video that shows Leo approaching a staircase, taking off, and gliding over the stairs to land near the bottom, the robot\u2019s motions are seamlessly graceful.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Leonardo: The Skateboarding, Slacklining Robot\" width=\"1020\" height=\"574\" src=\"https:\/\/www.youtube.com\/embed\/DhpMlI8jb5o?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>\u201cThere is a similarity between how a human wearing a jet suit controls their legs and feet when landing or taking off and how LEO uses synchronized control of distributed propeller-based thrusters and leg joints,\u201d&nbsp;<a href=\"https:\/\/www.caltech.edu\/about\/news\/leonardo-the-bipedal-robot-can-ride-a-skateboard-and-walk-a-slackline\">said<\/a>&nbsp;Soon-Jo Chung, one of the paper\u2019s authors a professor at Caltech. \u201cWe wanted to study the interface of walking and flying from the dynamics and control standpoint.\u201d<\/p>\n\n\n\n<p>Leo walks at a speed of 20 centimeters (7.87 inches) per second, but can move faster by mixing in some flying with the walking. How wide our steps are, where we place our feet, and where our torsos are in relation to our legs all help us balance when we walk. The robot uses its propellers to help it balance, while its leg actuators move it forward.<\/p>\n\n\n\n<p>To teach the robot to slackline\u2014which is much harder than walking on a balance beam\u2014the team overrode its feet contact sensors with a fixed virtual foot contact centered just underneath it, because the sensors weren\u2019t able to detect the line. The propellers played a big part as well, helping keep Leo upright and balanced.<\/p>\n\n\n\n<p>For the robot to ride a skateboard, the team broke the process down into two distinct components: controlling the steering angle and controlling the skateboard\u2019s acceleration and deceleration. Placing Leo\u2019s legs in specific spots on the board made it tilt to enable steering, and forward acceleration was achieved by moving the bot\u2019s center of mass backward while pitching the body forward at the same time.<\/p>\n\n\n\n<p>So besides being cool (and a little creepy), what\u2019s the goal of developing a robot like Leo? The paper authors see robots like Leo enabling a range of robotic missions that couldn\u2019t be carried out by ground or aerial robots.<\/p>\n\n\n\n<p>\u201cPerhaps the most well-suited applications for Leo would be the ones that involve physical interactions with structures at a high altitude, which are usually dangerous for human workers and call for a substitution by robotic workers,\u201d the paper\u2019s authors&nbsp;<a href=\"https:\/\/www.eurekalert.org\/news-releases\/930304?\">said<\/a>. Examples could include high-voltage line inspection, painting tall bridges or other high-up surfaces, inspecting building roofs or oil refinery pipes, or landing sensitive equipment on an extraterrestrial object.<\/p>\n\n\n\n<p>Next up for Leo is an upgrade to its performance via a more rigid leg design, which will help support the robot\u2019s weight and increase the thrust force of its propellers. The team also wants to make Leo more autonomous, and plans to add a&nbsp;<a href=\"https:\/\/www.caltech.edu\/about\/news\/neural-lander-uses-ai-land-drones-smoothly\">drone landing control algorithm<\/a>&nbsp;to its software, ultimately aiming for the robot to be able to decide where and when to walk versus fly.<\/p>\n\n\n\n<p>Leo hasn\u2019t quite achieved the wow factor of Boston Dynamics\u2019&nbsp;<a href=\"https:\/\/singularityhub.com\/2021\/01\/06\/start-the-new-year-right-by-watching-these-robots-awesome-dance-moves\/\">dancing robots<\/a>(or its Atlas that can&nbsp;<a href=\"https:\/\/singularityhub.com\/2021\/08\/18\/watch-boston-dynamics-atlas-robot-crush-a-new-parkour-course\/\">do parkour<\/a>), but it\u2019s on its way.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-background has-black-background-color has-black-color is-style-wide\"\/>\n\n\n\n<p><em>Image Credit: Caltech&nbsp;<a href=\"http:\/\/cast.caltech.edu\/\" target=\"_blank\" rel=\"noreferrer noopener\">Center for Autonomous Systems and Technologies\/<\/a><a href=\"https:\/\/www.science.org\/doi\/10.1126\/scirobotics.abf8136?_ga=2.112002372.1520562963.1633554653-1752701959.1632196350#F1\" target=\"_blank\" rel=\"noreferrer noopener\">Science Robotics<\/a><\/em><\/p>\n\n\n\n<p><strong>Author:<\/strong><\/p>\n\n\n\n<p>Vanessa is senior editor of Singularity Hub.
