These 3D-Printed Fish Bots Can Swarm and School

Researchers have made a smart school of robotic fish that swarm and swim just like the real deal, and they offer promising insights into how developers can improve decentralized, autonomous operations for other gizmos like self-driving vehicles and robotic space explorers. Also, they’re just pretty stinking cute.

These seven 3D-printed robots, or Bluebots, can synchronize their movements to swim in a group, or Blueswarm, without any outside control, per research published in Science Robotics this month from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering.

Equipped with two wide-angle cameras for eyes, each bot navigates their tank by tracking the LEDs lights on their peers. Based on the cues they observe, each robot reacts accordingly using an onboard Raspberry Pi computer and custom algorithm to gauge distance, direction, and heading.

“Each Bluebot implicitly reacts to its neighbors’ positions,” explains Florian Berlinger, a PhD candidate at SEAS and Wyss and first author of the research paper, per a press release. “So, if we want the robots to aggregate, then each Bluebot will calculate the position of each of its neighbors and move towards the center. If we want the robots to disperse, the Bluebots do the opposite. If we want them to swim as a school in a circle, they are programmed to follow lights directly in front of them in a clockwise direction.”

Previous robotic swarms could navigate in two-dimensional spaces, but operating in three-dimensional spaces like air or water has proven tricky. The goal of this research was to create a robofish swarm that could move in sync all on their own without the need for WiFi or GPS and without input from their human handlers.

Synology to enforce use of validated disks in enterprise NAS boxes. And guess what? Only its own disks exceed 4TB

Synology has introduced its first-ever list of validated disks and won’t allow other devices into its enterprise-class NAS devices. And in a colossal coincidence, half of the disks allowed into its devices – and the only ones larger than 4TB – are Synology’s very own HAT 5300 disks that it launched last week.

Seeing as privately held Synology is thought to have annual revenue of around US$350m, rather less than the kind of cash required to get into the hard disk business, The Register inquired if it had really started making drives or found some other way into the industry.

The Taiwanese network-attached-storage vendor told us the drives are Synology-branded Toshiba kit, though it has written its own drive firmware and that the code delivers sequential read performance 23 per cent beyond comparable drives. Synology told us its branded disks will also be more reliable because they have undergone extensive testing in the company’s own NAS arrays.

[…]

So to cut a long story short, if you want to get the most out of Synology NAS devices, you’ll need to buy Synology’s own SATA hard disk drives.

The new policy applies as of the release of three new Synology NAS appliances intended for enterprise use and will be applied to other models over time.

The new models include the RS3621RPxs, which sports an unspecified six-core Intel Xeon processor and can handle a dozen drives, then move data over four gigabit Ethernet ports. The middle-of-the-road RS3621xs+ offers an eight-core Xeon and adds two 10GE ports. At the top of the range, the RS4021xs+ stretches to 3U and adds 16GB of RAM, eight more than found in the other two models.

I guess HDD vendor lock in is a really really good reason to not buy Synology then.

Jeff Bezos To Step Down as Amazon CEO, Andy Jassy AWS Boss to succeed

Amazon announced on Tuesday that AWS CEO Andy Jassy will replace Jeff Bezos as CEO during the third quarter of this year. Bezos will transition to executive chair of Amazon’s board. In a statement, Bezos said: I’m excited to announce that this Q3 I’ll transition to Executive Chair of the Amazon Board and Andy Jassy will become CEO. In the Exec Chair role, I intend to focus my energies and attention on new products and early initiatives. Andy is well known inside the company and has been at Amazon almost as long as I have. He will be an outstanding leader, and he has my full confidence. This journey began some 27 years ago. Amazon was only an idea, and it had no name. The question I was asked most frequently at that time was, “What’s the internet?” Blessedly, I haven’t had to explain that in a long while. Today, we employ 1.3 million talented, dedicated people, serve hundreds of millions of customers and businesses, and are widely recognized as one of the most successful companies in the world. How did that happen? Invention. Invention is the root of our success. We’ve done crazy things together, and then made them normal. We pioneered customer reviews, 1-Click, personalized recommendations, Prime’s insanely-fast shipping, Just Walk Out shopping, the Climate Pledge, Kindle, Alexa, marketplace, infrastructure cloud computing, Career Choice, and much more. If you get it right, a few years after a surprising invention, the new thing has become normal. People yawn. And that yawn is the greatest compliment an inventor can receive.

Musk see: Watch SpaceX’s latest Starship rocket explode while trying to touch down • The Register

The latest prototype of SpaceX’s Starship rocket, the SN9, burst into flames as the vehicle attempted to land on Earth on Tuesday.

All eyes were on the craft after its predecessor, the SN8, exploded during touchdown in December in Boca Chica, Texas. You can watch today’s detonation in the video below. The accident occurs after six minutes into the flight (skip to 11:51 to see it burst into flames).

Like the previous launch, SN9 was also a high-altitude flight test. The vehicle got ten kilometres (32,800 feet) into the sky before shifting to a near-horizontal position to descend but, unfortunately, it exploded in the air before it could flip the right way up and touch down.

It’s not clear what caused the rapid unscheduled disassembly this time. It’s possible the rocket suffered the same mishap as SN8, considering how similar both launches unfolded. SpaceX CEO Elon Musk blamed SN8’s blowout on low pressure in the rocket’s fuel tank that caused it to meet the ground at a faster-than-desired velocity.

Rules? Pah

It has also emerged SpaceX asked the FAA for a waiver to exceed the limits of US federal public safety regulations during the SN8 launch. The regulator declined to issue the waiver, and SpaceX went ahead anyway with the fateful experiment.

As a result of that non-compliance, as the FAA put it, the agency demanded SpaceX carry out an investigation of the explosion and make changes to its public safety procedures in light of the failure. Those changes were approved by the regulator this week, and SpaceX was thus permitted to launch its SN9 craft.

Air Force Says KC-46 Is A “Lemon” That It’s Trying To Make Lemonade Out Of

The U.S. Air Force has described its bedeviled KC-46A Pegasus tanker as a “lemon,” amid ongoing problems that prevent it from performing its primary aerial refueling mission on a day-to-day basis. Now the Air Force is trying to find other ways to make use of these aircraft, of which it has already received 42 examples located at four operating bases.With deliveries set to continue at a rate of two aircraft per month, the service is now looking to put the Pegasus to work by fast-tracking at least some of the aircraft already delivered into “limited operations,” but probably not involving its core mission set of aerial refueling. Nevertheless, the move could enable the Pegasus to at least provide some utility during real-world operations as the Air Force counts down to the declaration of full operational capability, which won’t happen until late 2023 or 2024 at the earliest.U.S. Air Force/Louis BrisceseA KC-46A Pegasus arrives at Travis Air Force Base, California, in March 2017.“As I look over the 10 years, I have to say… right now where we’re at in the program is we’re making lemonade out of lemons,” General Jacqueline Van Ovost, the head of Air Mobility Command, told members of the press, as reported by the Defense One website. The embarrassing setbacks that have become an all-too-familiar aspect of the next-generation tanker program were also highlighted yesterday in an unusually candid tweet from the U.S. Transportation Command (USTRANSCOM), which admitted that problems with the tanker put “America’s ability to effectively execute day-to-day operations and war plans at risk.”

Tesla Claims Failing Touchscreens in 135000 car NHTSA Recall Were Only Meant to Last 5-6 Years Anyway

his week, Tesla finally gave in to the National Highway Traffic Safety Administration’s request to recall its Model S sedans and Model X SUVs over flash memory failures that will cause the cars’ signature 17-inch portrait-oriented central touchscreens to fail after a certain length of time—but not without pushback on the very definition of the word “defect,” according to a letter from Tesla’s legal department made public today.

Addressing federal regulators, Tesla Vice President of Legal Al Prescott made the case that the touchscreen failures didn’t constitute a defect worthy of a recall because the parts were only expected to last five to six years in the first place, which is certainly a novel strategy.

[…]

“[The eMMC flash memory] is inherently subject to wear, has a finite life (as NHTSA itself acknowledges), and may need replacement during the useful life of the vehicle…While the wear rate is heavily influenced by the active use of the center display system, even more so when the vehicle is in drive or charging, given a reasonable average daily use of 1.4 cycles, the expected life would be 5-6 years. NHTSA has not presented any evidence to suggest that this expected life is outside industry norms.”

Further, Prescott argued that it was wrong for the NHTSA to assert that the touchscreen “should last at least the useful life of the vehicle, essentially double its expected lifespan.” The fact that the average age of vehicles on U.S. roads hit an all-time high of 11.6 years in 2020, per CNBC.

He went on to call the eMMC “state of the art” for the time when it was designed and claimed the NHTSA’s regulations around defective parts were “anachronistic,” pushing back further on the NHTSA’s lifespan expectations

[…]

The fact that the flash memory device was only rated to handle half the lifespan of the average vehicle on the road raises numerous questions around new vehicles’ technology and planned obsolescence. If this was only expected to last five or six years, what else on the roads could fail earlier than consumers expect?

As the Washington Post notes, the way in which Teslas’ high-tech components wear could have dire consequences on the vehicles’ resale value. Unless there’s a way to recycle and reuse these throwaway components, the disposable nature of them could also leave a bad taste in eco-conscious consumers’ mouths.

Furthermore, why should consumers be expected to think that an internal component that’s required to access key safety features of the car should be a wear item? While Tesla has since added alerts that warn owners of a pending eMMC failure, a processor embedded in the internal components of a car isn’t something you can easily check on like a set of brake pads or tires, nor is it something that most consumers know to watch out for after so many miles of use.

The recall includes 134,951 Model S and Model X cars, making it Tesla’s biggest recall to date. It encompasses 2012 through 2018 Model S sedans as well as 2016 through 2018 Model X crossovers. This is fewer than the 158,000 cars requested by the NHTSA for recall, as Tesla excluded the vehicles that have already had memory upgrades or touchscreen replacements, reports the Washington Post.

Failures of the recalled memory chips are not the only issues that have dogged Model S and Model X touchscreens. Tesla CEO Elon Musk once bragged about sourcing the then-groundbreaking 17-inch screens outside of the usual automotive supply chain to save costs. Unfortunately, the screens weren’t built to handle the vibration loads and temperature fluctuations found in a car’s interior, causing them to prematurely yellow, bubble and even leak.

Wow, you really do get a piece of shit for buying a car from the most valuable car company in the world. Whilst Toyota has just stolen the crown from VW for selling the most cars per year.
