Leap Robot
Sabina Kehler
ANYmal can move in different walking gaits, enabling it to cover large distances in a short amount of time, climb steep slopes, deploy scientific instruments, and even recover in the unlikely event of a fall. The robot can also use its legs to dig channels in the soil, flip over boulders or smaller rocks for further inspection, and pick up samples.
Initially, the robot has been trained using a Reinforcement Learning approach in a virtual environment to simulate the lunar terrain, gravity and dust properties. It has also been deployed in the field for an outdoor hike.
The current design remains below 50 kg and includes 10 kg of scientific payload mass, notionally being capable of carrying multispectral sensors, ground penetrating radar, mass spectrometers, gravimeters, and other instrumentation.
The Europlanet Science Congress ( ) formerly the European Planetary Science Congress, is the annual meeting of the Europlanet Society. With a track record of 16 years, and regularly attracting around 1000 participants, EPSC is the largest planetary science meeting in Europe. It covers the entire range of planetary sciences with an extensive mix of talks, workshops and poster sessions, as well as providing a unique space for networking and exchanges of experiences.
The Europlanet Society promotes the advancement of European planetary science and related fields for the benefit of the community and is open to individual and organisational members. The Europlanet Society is the parent organisation of the Europlanet Science Congress (EPSC).
The European Astrobiology Network Association ( -net.eu), joins together people interested in the origins of life and the search for extraterrestrial life in the Solar System and beyond. This interdisciplinary domain involves scientists from multiple disciplines such as chemistry, physics, biology, geology, astronomy, and human sciences.
Europlanet 2024 RI has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 871149.
Europlanet AISBL (Association Internationale Sans But Lucratif - 0800.634.634) is hosted by the Department of Planetary Atmospheres of the Royal Belgian Institute for Space Aeronomy (BIRA-IASB), Avenue Circulaire 3, B-1180 Brussels, Belgium.
Yim works with Ronald Fearing, an electrical engineering and computer sciences professor at UC Berkeley, whose Biomimetic Millisystems Lab explores how the mechanics of animal movement can be applied to create more agile robots.
Now that Salto has a sense of itself and its own motion, the robot can make these calculations for itself, allowing Yim to take the robot outside and use a joystick and radio controller to tell it where to go.
Salto can now go out for walks on the Berkeley campus, where it has successfully maneuvered over sidewalks, brickwork and grass. The mathematical models that make this possible for Salto also could be generalized to control the motion of other kinds of robots, Yim said.
Roboticists at UC Berkeley have designed a small robot that can leap into the air and then spring off a wall, or perform multiple vertical jumps in a row, resulting in the highest robotic vertical jumping agility ever recorded. The agility of the robot opens new pathways of locomotion that were not previously attainable. The researchers hope that one day this robot and other vertically agile robots can be used to jump around rubble in search and rescue missions.
The work will be published Dec. 6 in the debut edition of the journal Science Robotics. The research was supported by the U.S. Army Research Laboratory under the Micro Autonomous Systems and Technology Collaborative Technology Alliance, and by the National Science Foundation.
Salto achieved 78 percent of the vertical jumping agility of a galago. Because of motor power limits, the best untethered robot before Salto had a vertical jumping agility of only 55 percent of a galago.
Generally it works ok. The main problem I am facing now is the control of fingers when my hand rolls to 90degree. This is when the two fingers are overlapping vertically and leap motion can only detect 1 of them!
Hello all, I am trying to build a robotic arm with servos and control it using a leap Motion sensor. I have seen many people online doing this before and I wanted to give it a try myself. I am having a couple of issues though. Most of the information online is pretty outdated and vague. I tried using the processing software, but the leap motion libraries I found were all outdated and wouldn't work for processing 4. I then tried using processing 2 which was what the libraries were being used for and that wouldn't work either considering it was from 2014. I was wondering if anyone could help me with this project and give me any insight on how I could control this arm with the motion sensor. I am also using a Arduino uno R3 for reference of that. Thank you all for your time!

In the not so distant future, first responders to a disaster zone may include four-legged, dog-like robots that can bound through a fire or pick their way through a minefield, rising up on their hind legs to turn a hot door handle or punch through a wall.
He attended Yonsei University in the city, where he studied mechanical engineering. In his second year, as has been mandatory in the country, he and other male students joined the South Korean army, where he served as a drill sergeant for two and a half years.
After enabling first sales of the product, he left the country and headed for Stanford University, where he enrolled in the mechanical engineering graduate program. There, he experienced his first taste of design freedom.
Kim joined the lab of Mark Cutkosky, an engineering professor who was looking for ways to design bioinspired robotic machines. In particular, the team was trying to develop a climbing robot that mimicked the gecko, which uses tiny hairs on its feet to help it climb vertical surfaces. Kim adapted this hairy mechanism in a robot and found that it worked.
He and his colleagues launched a startup to develop the gecko robot further, but again, Kim missed the thrill of being in the lab. He left the company soon after, for a postdoc position at Harvard University, where he helped to engineer the Meshworm, a soft, autonomous robot that inched across a surface like an earthworm. But even then, Kim was setting his sights on bigger designs.
Kim also teaches a class he created in 2013 called Bioinspired Robotics, in which 40 students team up in groups of four to design and build a robot inspired by biomechanics and animal motions. This past year, students showcased their designs in Lobby 7, including a throwing machine, a trajectory-optimizing kicking machine, and a kangaroo machine that hopped on a treadmill.
The Leap Motion ControllerTM is certified compliant to safety and electrical regulatory standards. Its robustness and external certification enable commercial projects, including sterile environments.
I use it on every stream. It's the perfect way to improve your communication with the viewers for an accessible price. People love the way I talk by moving my hands and can connect with them thanks to a better way to showing expressions. The only downside I found is that it gets reaaaally hot when used for a long period. but still works nonetheless. Just be careful with it if you're using it on your chest, find a phone or device holder for the neck to avoid this.
So I like the product. It does what it needs to. I would of left a 5 star if the sensor area wasn't smothered in adhesive residue. It took quite a while to clean and the sensor area had marks over it now from trying to clean it.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
