Startup founded by ex-Navy SEALs is building underwater robots to map the ocean

A tag team of deep-sea underwater robots sounds a whole lot like the setup for a Hollywood blockbuster. In fact, it’s the mission statement of a new startup with the appropriately cinematic name Terradepth. The company, founded by a pair of ex-Navy SEALs, is building autonomous submersible robots to help map parts of the ocean that are typically difficult to monitor. And it’s raised $8 million in funding to do so.

“Our highly intelligent unmanned ocean vehicle completely removes the need for humans at sea,” the company notes on its website. “The Terradepth AxV is deep-ocean rated, highly modular, and powers a large payload of sensors.”

The company’s mini-subs will reportedly boast an at-sea duration of 30 days, with an onboard recharging system capable of propelling them through the waves with a range of 1,000 nautical miles per deployment. The Terradepth AxV sub is 9.2 meters in length, and tips the scale at 3,700 kilos. (Although, of course, weight works a little bit differently underwater.) They will initially be able to reach depths of 1,000 meters, although plans are afoot to extend this to 3,000 meters, meaning that they’ll be able to journey to the bottom of many parts of the ocean. For context, the deepest point in the ocean, the Challenger Deep, is approximately 11,000 meters down.

“During at-sea operations, the topside AxV provides sea surface data collection, communications and navigation assistance, while the submerged AxV conducts its submerged mission,” the company notes. “The two AxVs can then switch roles once the submerged vehicle’s energy is expended to a predetermined level. Once surfaced, the vehicle employs a hybrid system of rechargeable lithium batteries and an air-dependent power plant capable of operating high-power, high-logistics instrument payloads.”

Underwater, the plan is for the robots to be able to able to gather data using multispectral imaging and other surveillance methods. This will be useful for both monitoring and forecasting services. Eventually, the goal is to be able to roll out entire networked fleets of autonomous robots. At present, Terradepth is planning on demonstrating its tech in an open-water environment in summer 2020.

Just when you thought it was safe to go back in the water, too.

DARPA is building a robotic space mechanic to fix satellites in orbit
weaponized satellites and the cold war in space standoff

DARPA, the Defense Advanced Research Projects Agency that’s responsible for developing emerging technologies for the U.S. military, is building a new high-tech spacecraft -- and it’s armed. In an age of Space Force and burgeoning threats like hunter-killer satellites, this might not sound too surprising. But you’re misunderstanding. DARPA’s new spacecraft, currently “in the thick of it” when it comes to development, is armed. As in, it has arms. Like the ones you use for grabbing things.

Armed robots aren’t new. Mechanical robot arms are increasingly widespread here on Earth. Robot arms have been used to carry out complex surgery and flip burgers. Attached to undersea exploration vehicles, they’ve been used to probe submerged wrecks. They’ve been used to open doors, defuse bombs, and decommission nuclear power plants. They’re pretty darn versatile. But space is another matter entirely.
The trouble with satellites
To understand the problem, imagine this scenario: You buy a supercar. It’s got every possible modern luxury, from its use of premium materials like titanium and carbon fiber-reinforced epoxy composites to its top-of-the-range engine, which purrs like the world’s most expensive kitten. Only there’s a catch. Although the car has been built to last, once you’ve driven it off the sales lot, you’re no longer allowed to repair or even tinker with it. Nothing. Nada. Zip. It’s not even possible to take it to the gas station when it needs to be refueled. Crazy, right? Even the most extravagant of sports stars, rappers or international arms dealers would probably think twice about that “deal.”

The world needs a drone traffic control system, so AirMap is building one
AirMap technology in use

One hundred years ago, in late February 1920, the United Kingdom’s Air Ministry commissioned a first-of-its-kind building at the newly opened Croydon Airport. The U.K.’s inaugural international airport (now defunct) was home to an elevated wooden hut with four large windows that was grandly referred to as the Aerodrome Control Tower. It was the world’s first air traffic control center.

At the time, air travel was still in its infancy. Although the first commercial flight had taken place six years earlier, the era of mass air travel remained several decades away. Along with providing weather information to pilots, the job of the people who worked in the Aerodrome Control Tower was to mark the progress of approximately 12 daily flights, tracked using basic radio-based navigation, on paper maps by way of pins and flags. It was, needless to say, a simpler time.

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

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.
