How robots learn to hike: ETH researchers look to improve four-legged ANYmal’s mobility

by Leave a Comment

By Christoph Elhardt

ETH Zurich researchers led by Marco Hutter have developed a new control approach that enables a legged robot, called ANYmal, to move quickly and robustly over difficult terrain.

Thanks to machine learning, the robot can combine its visual perception of the environment with its sense of touch for the first time.

Steep sections on slippery ground, high steps, scree and forest trails full of roots: the path up the 1,098-​metre-high Mount Etzel at the southern end of Lake Zurich is peppered with numerous obstacles.

Eavesdropping on our thoughts helps create robots like us

by Leave a Comment

Can intelligence be taught to robots? Advances in physical reservoir computing, a technology that makes sense of brain signals, could contribute to creating artificial intelligence machines that think like us.

In Applied Physics Letters, from AIP Publishing, researchers from the University of Tokyo outline how a robot could be taught to navigate through a maze by electrically stimulating a culture of brain nerve cells connected to the machine.

These nerve cells, or neurons, were grown from living cells and acted as the physical reservoir for the computer to construct coherent signals. [Read more…] about Eavesdropping on our thoughts helps create robots like us

Russia’s Sber Bank establishes new science award with $820,000 prize money

by Leave a Comment

Sber, Russia’s largest banking group, has created a competition to find innovative startup companies in the country, pledging to give approximately $270,000 in prize money to the winners.

It’s officially the “Year of Science and Technology” in Russia, so Sber decided to mark it by establishing the Sber Science Award, which is planned to be an annual science award to support the research and development efforts that have a considerable potential to impact the progress of science and technology.

Three winners will receive 20 million roubles (approximately $270,000) in prizes. The total prize pool of the science award reaches 60 million roubles (approximately $820,000). [Read more…] about Russia’s Sber Bank establishes new science award with $820,000 prize money

Cleveland Clinic develops bionic arm that restores ‘natural behaviors’

by Leave a Comment

Cleveland Clinic researchers have engineered a “first-of-its-kind bionic arm” for patients with upper-limb amputations that allows wearers to think, behave and function like a person without an amputation, according to new findings published in Science Robotics.

The Cleveland Clinic-led international research team developed the bionic system that combines three important functions – intuitive motor control, touch and grip kinesthesia, the intuitive feeling of opening and closing the hand.

Collaborators included University of Alberta and University of New Brunswick. [Read more…] about Cleveland Clinic develops bionic arm that restores ‘natural behaviors’

Scientists research ‘matter waves’ to shine light on post electronics future

by Leave a Comment

Most modern technologies owe their success to advances in electronics. These devices harness the flow of electrons in different ways to create computers, charge batteries, light-up displays, and move motors.

Now researchers are starting to explore ways to harness the flow of waves of whole atoms, called matter waves, to enable new kinds of sensors, computers, and scientific research.

This new field has been named atomtronics, owing to the focus on finding ways to move whole atoms rather than electrons in traditional electronics devices. [Read more…] about Scientists research ‘matter waves’ to shine light on post electronics future

Autonomous excavators ready for around the clock real-world application

by Leave a Comment

Researchers from Baidu Research and the University of Maryland have developed a robotic excavator system that integrates perception, planning, and control capabilities to enable material loading over a long duration with no human intervention

Researchers from Baidu Research Robotics and Auto-Driving Lab (RAL) and the University of Maryland, College Park, have introduced an autonomous excavator system (AES) that can perform material loading tasks for a long duration without any human intervention while offering performance closely equivalent to that of an experienced human operator.

AES is among the world’s first uncrewed excavation systems to have been deployed in real-world scenarios and continuously operating for over 24 hours, bringing about industry-leading benefits in terms of enhanced safety and productivity.

The researchers described their methodology in a research paper published on June 30, 2021, in Science Robotics. [Read more…] about Autonomous excavators ready for around the clock real-world application

Deep learning networks prefer the human voice – just like we do

by Leave a Comment

Columbia engineers demonstrate that AI systems might reach higher performance if programmed with sound files of human language rather than with binary data labels. (See video below.)

The digital revolution is built on a foundation of invisible 1s and 0s called bits.

As decades pass, and more and more of the world’s information and knowledge morph into streams of 1s and 0s, the notion that computers prefer to “speak” in binary numbers is rarely questioned.

According to new research from Columbia Engineering, this could be about to change. [Read more…] about Deep learning networks prefer the human voice – just like we do

MIT CSAIL’s robo-starfish enables closer study of aquatic life

by Leave a Comment

Scientists have invented a ‘robo-starfish’ which give us more insights into aquatic life, as Adam Conner-Simons, or MIT CSAIL, reports. (See video below.)

Biologists have long experienced the challenges of documenting ocean life, with many species of fish proving quite sensitive to the underwater movements of humans.

As a possible solution, computer scientists have been developing special marine robots that can stealthily move among their carbon-based counterparts. In 2018, for example, a team from MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) fabricated a soft robotic fish that autonomously swam with real fish along the coral reefs of Fiji.

However, the complex dynamics of how water moves – and its ability to quickly ruin some perfectly good electronics systems – have made underwater robots especially difficult to develop compared to ones for air or land.

Artificial skin brings robots closer to ‘touching’ human lives

by Leave a Comment

Modern-day robots are often required to interact with humans intelligently and efficiently, which can be enabled by providing them the ability to perceive touch.

However, previous attempts at mimicking human skin have involved bulky and complex electronics, wiring, and a risk of damage.

In a recent study, researchers from Japan sidestep these difficulties by constructing a 3D vision-guided artificial skin that enables tactile sensing with high performance, opening doors to innumerable applications in medicine, healthcare, and industry.

Swiss university developing mobile robot that learns on the job

by Leave a Comment

A team from the Autonomous Systems Lab at the public research university ETH Zurich in Switzerland is creating robots and intelligent systems that are able to learn on the job. (See video below.)

The team’s machine – which consists of a robotic arm mounted on a mobile platform – can “autonomously operate in complex and diverse environments”, says an article on Clearpath Robotics’ website.

Using a Clearpath Ridgeback as a base and equipped with a Franka Emika Panda manipulator arm (called RoyalPanda, that is Ridgeback + Panda), the team is experimenting with a series of different scenarios to develop best practices of how a robot could “learn”.
