The airspace above future battlefields is expected to be increasingly congested with large numbers of unmanned aerial systems, manned aircraft, munitions and missiles filling the skies. To de-conflict airspace activities of friendly forces and rapidly counter an enemy’s actions on the battlefield requires new technologies to effectively integrate effects from all domains.
Video Friday is your weekly selection of awesome robotics videos, collected by your Automaton bloggers. We’ll also be posting a weekly calendar of upcoming robotics events for the next few months; here’s what we have so far (send us your events!):
Let us know if you have suggestions for next week, and enjoy today’s videos.
In 2017, a team of USC Viterbi researchers created ADAMMS (Agile Dexterous Autonomous Mobile Manipulation System), a robot designed to support repetitive human tasks, like transporting equipment or tending a 3D printer at 3 a.m. ADAMMS can perform specific actions like opening doors or picking up objects autonomously. These researchers, including postdoctoral researcher in the USC Viterbi Department of Aerospace and Mechanical Engineering Pradeep Rajendran, AME Ph.D student Shantanu Thakar, Department of Computer Science master’s student Hyojeong Kim and M.S. AME’18 Vivek Annem, envisioned a tool that could support humans remotely.

After consuming magic mushrooms in Basel, Switzerland, I ran into Albert Hofmann, the chemist who catalyzed the psychedelic era.
Algae biofuel certainly faces an uphill battle these days, what with the global oil price crash and competition from electric vehicles. Nevertheless, there may be a glimmer of hope for algae biofuel fans, in the form of an ultra-fast 3D printer housed in a California laboratory. In an interesting sustainability twofer, the same machine might also spit out an assist for the world’s ailing coral reefs.
Inspired by how human bone and colorful coral reefs adjust mineral deposits in response to their surrounding environments, Johns Hopkins researchers have created a self-adapting material that can change its stiffness in response to the applied force. This advancement can someday open the doors for materials that can self-reinforce to prepare for increased force or stop further damage. A report of the findings was published today in Advanced Materials.
“Imagine a bone implant or a bridge that can self-reinforce where a high force is applied without inspection and maintenance. It will allow safer implants and bridges with minimal complication, cost and downtime,” says Sung Hoon Kang, an assistant professor in the Department of Mechanical Engineering, Hopkins Extreme Materials Institute, and Institute for NanoBioTechnology at The Johns Hopkins University and the study’s senior author.
While other researchers have attempted to create similar synthetic materials before, doing so has been challenging because such materials are difficult and expensive to create, or require active maintenance when they are created and are limited in how much stress they can bear. Having materials with adaptable properties, like those of wood and bone, can provide safer structures, save money and resources, and reduce harmful environmental impact.

Why is Alcor in Arizona? The main reason is that the risk of earthquakes and other natural disasters is fairly low. People opting for cryonics expect that their bodies might be in stasis for timescales measured in centuries.
As far as financial matters go, many of Alcor’s clients use life insurance policies to cover the cost of preservation and maintenance ($200,000 for a whole body or $80,000 for just the head). People use trust funds if they have net worth they want to recover when revived in the future.
The rationale presented to those considering cryonics is that there’s no guarantee they will ever be revived, but that it is reasonable that they might be. Along with chemicals called cryoprotectants, bodies getting preserved receive a host of medications. The list of the agents used is constantly evolving and continuing research is likely to reveal alternative methods that preserve organ function and cell integrity better. This means that cryopreservation is likely to work better years and decades into the future than it works now, even before getting to the milestone of having somebody revived.
A pattern is emerging among COVID-19 patients arriving at hospitals in New York: Beyond fever, cough and shortness of breath, some are deeply disoriented to the point of not knowing where they are or what year it is.
At times this is linked to low oxygen levels in their blood, but in certain patients the confusion appears disproportionate to how their lungs are faring.
Jennifer Frontera, a neurologist at NYU Langone Brooklyn hospital seeing these patients, told AFP the findings were raising concerns about the impact of the coronavirus on the brain and nervous system.
Researchers with the world’s gravitational wave detectors said today they had picked up vibrations from a cosmic collision that harmonized with the opening notes of an Elvis Presley hit. The source was the most exotic merger of two black holes detected yet—a pair in which one weighed more than three times as much as the other. Because of the stark mass imbalance, the collision generated gravitational waves at multiple frequencies, in a harmony Elvis fans would recognize. The chord also confirms a prediction of Einstein’s theory of gravity, or general relativity.
Such mismatched mass events could help theorists figure out how pairs of black holes form in the first place. “Anything that seems to be at the edge of our predictions is most interesting,” says Chris Belczynski, a gravitational theorist at the Polish Academy of Sciences in Warsaw, who was not involved in the observation. But the one event is “not quite in the regime where you can tell the different formation [routes] apart.”
Physicists first detected gravitational waves in 2015, when the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of detectors in Washington and Louisiana, spotted two black holes spiraling into each other, generating infinitesimal ripples in spacetime. Two years later, the Virgo detector near Pisa, Italy, joined the hunt, and by August 2017, the detectors had bagged a total of 10 black hole mergers.
