Meet South Korea’s autonomous jellyfish-murdering robots

Normally, I’m completely against the idea of autonomous killing machines. The way I see it, every murderous robot we build to operate without human intervention – no matter how sophisticated and human-friendly it may be – inches us closer toward an Asmiovian dystopia in which humanity terrorized and enslaved by giant mechanized overlords. But, if our drones of death are aimed at humanity’s most fearsome gelatinous enemy, the jellyfish, I won’t make a fuss.

In case you haven’t heard, jellyfish populations are on the rise, and have been for the past few years. Some believe that this is linked to climate change and rising ocean temperatures, others say it’s completely unrelated; but regardless of what’s causing it, there’s no denying that this population boom is problematic. Just last week, a swarm of the creatures (called a “bloom”) caused a Swedish nuclear power plant to shut down when it clogged up the pipes that pump cool ocean water to the plant’s reactor. And that’s only the most recent incident – similar shutdowns have been happening periodically across the globe for years.

South Korea has a particularly rough time keeping the gelatinous hordes away from its coastline, so researchers at the Urban Robotics Lab of the Korea Advanced Institute of Science and Technology built something a bit more *cutting edge* than nets and trawlers. JEROS (short for Jellyfish Elimination RObotic Swarm) is basically a giant autonomous blender designed to hunt these gooey little bastards. Check out this video to see it in action.

The bots that make up the swarm float on the surface of the water and use small motors to propel themselves forward. Using a combination of GPS and an array of cameras, each bot in the swarm is able to communicate with the others to orchestrate attacks. Once it acquires a target, JEROS will corral the bloom, converge on it, and liquify the lot of them using special jellyfish-pulverizing propellors. Apparently this system can destroy nearly one ton of jellyfish an hour, making it much faster and efficient than current net-based removal methods.

The Urban Robotics team says it’s working to commercialize JEROS within the next year, and hopes to apply the technology to more than just jellyfish murder. In the future, the team hopes to use JEROS for things like patrolling beaches, oil spill cleanup, and marine debris removal.

Exosuits for everybody: Meet the company that’s making wearable robots mainstream
Roam Robotics exosuit

Watching a person walk for the first time in twenty years is an image that sticks with you. That’s exactly what Tim Swift was fortunate enough to witness as part of the three-person original team behind the Ekso wearable bionic suit, a set of mechanical robot legs designed to help people with paralysis take their first assisted steps. Swift was the Senior Controls Engineer and, later, Research Manager at Ekso Bionics; building wearable robotics technology that previously existed only as a sci-fi fever dream. “It’s amazing tech,” he told Digital Trends. “I love it like a child.”

As astonishing as the sight was, however, it wasn’t the one that stuck with him the most. The image most indelibly burned into his memory was the one which frequently followed the robot rehab sessions; the one that we might think of as the comedown. “Those moments were great and life-affirming, but at the end of the hour [the person would] transfer out of the device and back into their wheelchair, and wheel out the door like it didn’t happen,” Swift said.

FedEx’s autonomous delivery robot sent packing by New York City
FedEx-SameDay-Bots

Delivery robots suffered a setback this week when New York City made it clear they’re not welcome there. At least, for now.

On Monday, November 25, just a few days after a FedEx “SameDay Bot” autonomous robot was spotted trundling along a Manhattan street, lawyers for the New York City Department of Transportation sent a strongly worded cease-and-desist letter to the shipping giant, CNN reported.

Meet the robotic pioneers that will help humanity colonize Mars
A rendering of Mars 2020 rover, to be launched on its journey to Mars next year.

From NASA's upcoming Moon to Mars mission to Elon Musk's ambitious plans to use a SpaceX Starship to eventually colonize Mars, the race to populate the Red Planet is already on. But before humans can visit Mars and set up any kind of long-term base there, we need to send out scouts to see the lay of the land and prepare it for manned missions.

The mechanical pioneers we'll be sending to Mars in the coming years will follow in the tire tracks of explorers like the Curiosity rover and the Insight lander, but the next generation of Martian robotics will use sophisticated AI, novel propulsion methods, and flexible smallsats to meet the challenges of colonizing a new world.
Designing for the Mars environment
There are distinct difficulties in building machines which can withstand the Martian environment. First, there's the cold, with temperatures averaging around minus 80 degrees Fahrenheit and going down to minus 190 degrees Fahrenheit at the poles. Then there's the thin atmosphere, which is just one percent the density of Earth's atmosphere. And then there's the troublesome dust that gets kicked up in any operations on the planet's surface, not to mention the intense radiation from the Sun's rays.
