Robot therapist hits the spot with athletes

Posted by in categories: 3D printing, biotech/medical, robotics/AI

Perfect; I actually was thinking about robots as personal trainers and sparring partners for boxers. I love boxing as a workout and had thought about having a robot as a sparring partner as well as my weight/ strength training.

BTW — another concept is to build into the weight training machines AI technology to assist users. Think about if the machine sensors that the users’ muscle is about to strain that the machine takes the weight off or lightens the weight on the user of the equipment. And, if the machine senses that the person is about to have an heart attack, etc. that the equipment contacts 911, etc.

Trials of a prototype robot for sports therapy have just begun in Singapore, to create a high quality and repeatable treatment routine to improve sports recovery, reducing reliance on trained therapists.

Crawling robot built from sea slug parts and a 3D printed body

Posted by in categories: 3D printing, neuroscience, robotics/AI

Researchers at Case Western Reserve University have combined tissues from a sea slug with flexible 3D printed components to build “biohybrid” robots that crawl like sea turtles on the beach.

A muscle from the slug’s mouth provides the movement, which is currently controlled by an external electrical field. However, future iterations of the device will include ganglia, bundles of neurons and nerves that normally conduct signals to the muscle as the slug feeds, as an organic controller.

The researchers also manipulated collagen from the slug’s skin to build an organic scaffold to be tested in new versions of the robot.

Can we find a quantum-resistant algorithm before it’s too late?

Posted by in categories: computing, information science, internet, quantum physics, security

The warning from QuintessenceLabs’ CTO John Leisoboer is stark. “When sufficiently powerful quantum computers become generally available,” he says, “it’s guaranteed to break all existing cryptographic systems that we know of.”

In other words, he adds, “Everything that we’re doing today will be broken.”

It’s a sentiment echoed by Google’s Chrome security software engineer Matt Braithwaite who wrote in a blog post earlier this month that “a hypothetical, future quantum computer would be able to retrospectively decrypt any internet communication that was recorded today”.

DARPA’s New Robot Is Ready To Go Submarine Hunting

Posted by in categories: military, robotics/AI

DARPA’s newest Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) can travel on the high seas at speeds up to 27 knots for months on end without a single crew member.

DARPA's New Robot Is Ready to Go Submarine Hunting

The 39.62m ACTUV can be remote-controlled, but its primary use is as an autonomous vessel that can operate safely near manned ships and accommodate all weather conditions. No crew means greater safety for potentially dangerous missions like countermining and submarine tracking.

5 Reasons To ‘Farm’ In Low-Earth Orbit

Posted by in categories: food, habitats, space travel, sustainability

Large Earth-orbiting greenhouses will someday likely be as commonplace as peanut acreage on Georgia’s coastal plains.

Low-Earth orbit (LEO) would hardly appear to be the best place to take up farming. But both NASA and the burgeoning commercial space industry are already planning for a time when in addition to on-orbit space hotels and new research stations, there will also be Earth-orbiting greenhouses. Such structures will provide a horn of plenty for growing numbers of LEO residents and astronauts venturing beyond Earth orbit to the Moon, Mars or even the Main Asteroid Belt.

The initial case for LEO agriculture would be to feed a growing population of space-dwellers — either using a greenhouse that remained permanently attached to the LEO habitat, or a greenhouse that was free-flying and uncrewed.

SpaceX successfully lands Falcon 9 rocket on solid ground for the second time

Posted by in categories: drones, robotics/AI, space travel

SpaceX has successfully landed another Falcon 9 rocket after launching the vehicle into space this evening from Cape Canaveral, Florida. Shortly after takeoff, the vehicle touched down at SpaceX’s Landing Complex 1 — a ground-based landing site that the company leases at the Cape. It marks the second time SpaceX has pulled off this type of ground landing, and the fifth time SpaceX has recovered one of its rockets post-launch. The feat was accomplished a few minutes before the rocket’s second stage successfully put the company’s Dragon spacecraft into orbit, where it will rendezvous with the International Space Station later this week.

It’s also the first time this year SpaceX has attempted to land one of its rockets on land. For the past six launches, each rocket has tried landing on an autonomous drone ship floating in the ocean. That’s because drone ship landings require a lot less fuel to execute than ground landings (something we explain here). If a rocket has to accelerate super fast during launch — such as those going to high orbits or ones carrying heavy payloads — it uses up a lot of fuel during the initial takeoff. That leaves less fuel for the rocket to land back on Earth, which means a drone ship landing is sometimes the only option. But for this launch, the mission requirements allowed for a successful landing on ground.
