LEONARDO, the Bipedal Robot, Can Ride a Skateboard and Walk a Slackline

Researchers at Caltech have built a bipedal robot that combines walking with flying to create a new type of locomotion, making it exceptionally nimble and capable of complex movements. LEO carves out a new type of locomotion somewhere between walking and flying. Image credit: Caltech Part walking robot, part flying drone, the newly developed LEONARDO (short for LEgs ONboARD drOne, ...

Precise Object Placement with Pose Distance Estimations for Different Objects and Grippers

In order to grasp and manipulate objects in undefined poses, robots must perceive their environment and plan corresponding actions accordingly. Industrial robot. Image credit: jarmoluk via Pixabay (Free Pixabay licence) A recent study on arXiv.org focuses on robotic bin-picking, where multiple rigid objects of different types are stored chaotically in a bin. The robot has to pick the objects and ...

Using Bundles of Fibers, Robots Mimic Nature

Octopus tentacles can move in many directions, but also form stiff joint-like structures for more precise movements. Caterpillars can travel by using inchworm movements, as well as coil up and propel themselves away from predators. Such capabilities allow organisms to thrive in the natural, unstructured world. Creating robots with that kind of fluidity of movement, though, has been a challenge. ...

NASA Robots Compete in DARPA’s Subterranean Challenge Final

Led by NASA JPL, Team CoSTAR will participate in the SubT final this week to demonstrate multi-robot autonomy in a series of tests in extreme environments. Eight teams featuring dozens of robots from more than 30 institutions, including NASA’s Jet Propulsion Laboratory in Southern California, will converge in a former Kentucky limestone mine from Sept. 21 to 24 to participate ...

Focus on Impact: Indoor Exploration with Intrinsic Motivation

Robotic exploration is the task of autonomously navigating an unknown environment to gather sufficient information to represent it. Usually, deep reinforcement learning-based algorithms are employed, and extrinsic rewards based on occupancy anticipation are used in training. However, such rewards require knowledge about the precise layout of the training environments, which is expensive to gather. Therefore, a recent paper proposes to ...

Take a 3D Spin on Mars and Track NASA’s Perseverance Rover

Two interactive web experiences let you explore the Martian surface, as seen by cameras aboard the rover and orbiters flying overhead. It’s the next best thing to being on Mars: Two online interactive experiences let you check out Jezero Crater – the landing site and exploration locale for NASA’s Perseverance rover – without leaving our planet. NASA’s Mars Perseverance rover ...

ExoMars Will be Drilling 1.7 Meters to Pull its Samples From Below the Surface of Mars

In about a year (Sept. 20th, 2021), the Rosalind Franklin rover will depart for Mars. As the latest mission in the ESA’s and Roscosmos’ ExoMars program, Rosalind Franklin will join the small army of orbiters, landers, and rovers that are working to characterize the Martian atmosphere and environment. A key aspect of the rover’s mission will involve drilling into the ...

Making self-driving cars safer through keener robot perception

PhD student Heng Yang is developing algorithms to help driverless vehicles quickly and accurately assess their surroundings. Aviation became a reality in the early 20th century, but it took 20 years before the proper safety precautions enabled widespread adoption of air travel. Today, the future of fully autonomous vehicles is similarly cloudy, due in large part to safety concerns. Image ...

Air-powered computer memory helps soft robot control movements

“Airhead” robot uses pneumatic RAM to play piano. Engineers at UC Riverside have unveiled an air-powered computer memory that can be used to control soft robots. The innovation overcomes one of the biggest obstacles to advancing soft robotics: the fundamental mismatch between pneumatics and electronics. The work is published in the open-access journal, PLOS One. Pneumatic soft robots use pressurized air ...
