DARPA Selects Teams to Further Advance Dogfighting Algorithms

Posted by in categories: information science, military, robotics/AI

DARPA recently awarded contracts to five companies to develop algorithms enabling mixed teams of manned and unmanned combat aircraft to conduct aerial dogfighting autonomously.

Boeing, EpiSci, Georgia Tech Research Institute, Heron Systems, and physicsAI were chosen to develop air combat maneuvering algorithms for individual and team tactical behaviors under Technical Area (TA) 1 of DARPA’s Air Combat Evolution (ACE) program. Each team is tasked with developing artificial intelligence agents that expand one-on-one engagements to two-on-one and two-on-two within-visual-range aerial battles. The companies’ algorithms will be tested in each of three program phases: modeling and simulation, sub-scale unmanned aircraft, and full-scale combat representative aircraft scheduled in 2023.

“The TA1 performers include a large defense contractor, a university research institute, and boutique AI firms, who will build upon the first-gen autonomous dogfighting algorithms demonstrated in the AlphaDogfight Trials this past August,” said Air Force Col. Dan “Animal” Javorsek, program manager in DARPA’s Strategic Technology Office. “We will be evaluating how well each performer is able to advance their algorithms to handle individual and team tactical aircraft behaviors, in addition to how well they are able to scale the capability from a local within-visual-range environment to the broader, more complex battlespace.”

DARPA Awards Contracts for Work on Spinal Cord Injury Treatment

Posted by in categories: neuroscience, robotics/AI

Spinal cord injury (SCI) is of significant concern to the Department of Defense. Of the 337,000 Americans with serious SCIs, approximately 44,000 are veterans, with 11,000 new injuries occurring each year.1 SCI is a complex condition – the injured often face lifelong paralysis and increased long-term morbidity due to factors such as sepsis and autonomic nervous system dysfunction. While considerable research efforts have been devoted toward restorative and therapeutic technologies to SCIs, significant challenges remain.

DARPA’s Bridging the Gap Plus (BG+) program aims to develop new approaches to treating SCI by integrating injury stabilization, regenerative therapy, and functional restoration. Today, DARPA announced the award of contracts to the University of California-Davis, Johns Hopkins University, and the University of Pittsburgh to advance this crucial work. Multidisciplinary teams at each of these universities are tasked with developing systems of implantable, adaptive devices that aim to reduce injury effects during early phases of SCI, and potentially restore function during the later chronic phase.

“The BG+ program looks to create opportunities to provide novel treatment approaches immediately after injury,” noted Dr. Al Emondi, BG+ program manager. “Systems will consist of active devices performing real-time biomarker monitoring and intervention to stabilize and, where possible, rebuild the neural communications pathways at the site of injury, providing the clinician with previously unavailable diagnostic information for automated or clinician-directed interventions.”

Scientists uncover secrets to designing brain-like devices

Posted by in category: robotics/AI

Even with decades of unprecedented development in computational power, the human brain still holds many advantages over modern computing technologies. Our brains are extremely efficient for many cognitive tasks and do not separate memory and computing, unlike standard computer chips.

In the last decade, the new paradigm of neuromorphic computing has emerged, inspired by neural networks of the brain and based on energy-efficient hardware for information processing.

To create devices that mimic what occurs in our brain’s neurons and synapses, researchers need to overcome a fundamental molecular engineering challenge: how to design devices that exhibit controllable and energy-efficient transition between different resistive states triggered by incoming stimuli.

Concurrent sharing of an avatar body

Posted by in categories: biotech/medical, internet, robotics/AI, virtual reality

The COVID-19 crisis has led to a significant increase in the use of cyberspace, enabling people to work together at distant places and interact with remote environments and individuals by embodying virtual avatars or real avatars such as robots. However, the limits of avatar embodiment are not clear. Furthermore, it is not clear how these embodiments affect the behaviors of humans.

Therefore, a research team comprising Takayoshi Hagiwara () and Professor Michiteru Kitazaki from Toyohashi University of Technology; Dr. Ganesh Gowrishankar (senior researcher) from UM-CNRS LIRMM; Professor Maki Sugimoto from Keio University; and Professor Masahiko Inami from The University of Tokyo aimed to develop a novel collaboration method with a shared avatar, which can be controlled concurrently by two individuals in VR, and to investigate human motor behaviors as the avatar is controlled in VR.

Full movements of two participants were monitored via a motion-capture system, and movements of the shared avatar were determined as the average of the movements of the two participants. Twenty participants (10 dyads) were asked to perform reaching movements with their towards target cubes that were presented at various locations. Participants exhibited superior reaction times with the shared avatar than individual reaction times, and the avatar’s hand movements were straighter and less jerky than those of the participants. The participants exhibited a sense of agency and body ownership towards the shared avatar although they only formed a part of the shared avatar.

Machine learning advances materials for separations, adsorption and catalysis

Posted by in categories: chemistry, robotics/AI

An artificial intelligence technique—machine learning—is helping accelerate the development of highly tunable materials known as metal-organic frameworks (MOFs) that have important applications in chemical separations, adsorption, catalysis, and sensing.

Utilizing data about the properties of more than 200 existing MOFs, the machine learning platform was trained to help guide the development of new materials by predicting an often-essential property: water stability. Using guidance from the , researchers can avoid the time-consuming task of synthesizing and then experimentally testing new candidate MOFs for their aqueous stability. Already, researchers are expanding the model to predict other important MOF properties.

Supported by the Office of Science’s Basic Energy Sciences program within the U.S. Department of Energy (DOE), the research was reported Nov. 9 in the journal Nature Machine Intelligence. The research was conducted in the Center for Understanding and Control of Acid Gas-Induced Evolution of Materials for Energy (UNCAGE-ME), a DOE Energy Frontier Research Center located at the Georgia Institute of Technology.

Magnetic FreeBOT balls make giant leap for robotics

Posted by in category: robotics/AI

A unique type of modular self-reconfiguring robotic system has been unveiled. The term is a mouthful, but it basically refers to a robotic enterprise that can construct itself out of modules that connect to one another to achieve a certain task.

There has been great interest in such machines, also referred to as MSRRs, in recent years. One recent project called simply Space Engine can construct its own physical space environment to meet living, work and recreational needs. It accomplishes those tasks by generating its own kinetic forces to move and shape such spaces. It does this through adding and removing electromagnets to shift and construct modules into optimum room shapes.

The first Tesla taxi in NYC just hit the streets as the city’s only electric yellow cab. The plan is for hundreds more to join it

Posted by in categories: robotics/AI, sustainability, transportation

Gonzalez thinks that Tesla taxis could help reinvigorate the city’s yellow-cab industry, which has taken a major hit from ride-hailing services like Uber, Via, and Lyft. He also predicts that the city could, for sustainability reasons, start mandating electric cabs, so he’s looking to get ahead of the curve, even if the commercial charging infrastructure isn’t quite there yet.

Drive Sally plans to bring hundreds of Teslas to New York’s streets in the near future, but for now, the company is still working out the kinks. Gonzalez suspects that the EVs may be better suited for for-hire “black cars” than yellow cabs, and he also said that the more-spacious Model Y would likely work better as a cab than the Model 3, but they’re still too expensive.

Neural’s market outlook for artificial intelligence in 2021 and beyond

Posted by in categories: Elon Musk, finance, robotics/AI, singularity, transportation

The year is coming to a close and it’s safe to say Elon Musk’s prediction that his company would field one million “robotaxis” by the end of 2020 isn’t going to come true. In fact, so far, Tesla’s managed to produce exactly zero self-driving vehicles. And we can probably call off the singularity too. GPT-3 has been impressive, but the closer machines get to aping human language the easier it is to see just how far away from us they really are.

So where does that leave us, ultimately, when it comes to the future of AI? That depends on your outlook. Media hype and big tech’s advertising machine has set us up for heartbreak when we compare the reality in 2020 to our 2016-era dreams of fully autonomous flying cars and hyper-personalized digital assistants capable of managing the workload of our lives.
