Scientists test underwater “LarvalBot” in effort to rebuild coral reefs damaged by climate change

Published

on

An underwater robot previously used to eliminate invasive species in coral reefs has been repurposed to spread baby coral larvae where needed. Renamed “LarvalBot” from its previous “RangerBot” title, this machine is currently the only one of its kind, and it represents an important step in the direction of coral reef restoration. The machine was developed by scientists from Queensland University of Technology (QUT) and Southern Cross University (SCU) in Australia with funding from the Great Barrier Reef Foundation.

The technique used by the bot is called “larval restoration”, and it begins with the collection of millions of coral spawn by scientists. The spawn are next reared inside nearby large floating enclosures, and once they have developed into larvae, the coral young are put into LarvalBot and squirted around dead reef areas. From there, the baby coral can settle, grow, and gradually restore damage from events like coral bleaching. It will take about three years for the corals to become mature enough to reproduce and spread on their own.

With LarvalBot’s assistance, the spread of coral larvae will be enhanced up to 100-times what is achieved naturally. Given the unnatural threats of destructive fishing practices and pollution to the reefs, artificial means of helping nature may be the only way they can hope to survive in the long-term. Scientists from QUT and SCU are currently focused on speeding up the recovery of parts of the Great Barrier Reef affected by coral bleaching, a condition which occurs after coral lose their symbiotic algae, causing the living tissues to become transparent.

Coral bleaching will kill the corals affected if the environmental cause continues for too long. There are several stressors which can lead to the bleaching; however, the leading cause today is warming temperatures. A difference of two degrees Fahrenheit above the seasonal maximum can trigger the condition.

The upcoming annual season for coral spawning occurs in late November where the corals will synchronically bloom all over the world. Triggered by the lunar cycle and water temperature, coral reef colonies will release their eggs and sperm in a mass event resulting in clouds of white, yellow, and orange in all reef regions. After the blooms rise to the surface where fertilization occurs, the embryos develop into larvae, and then they fall to the sea floor in the days and weeks following where they will hopefully attach to substrate and grow into a new colony.

LarvalBot’s developers hope to have 2-3 similar robots ready to help collect the blooms resulting from the November event. According to these scientists, the bots will carry about 200,000 and 1.2 million larvae apiece and seed the reefs at a rate of 1500 square meters per hour. It’s not quite enough to consider the bots official coral baby mothers, but perhaps the actions could be considered motherly.

Tesla Robotaxi is headed to New York City, but one thing is in its way

Tesla is working to hire Vehicle Operators in New York City, but the company still needs some regulatory hurdles to go through.

Tesla Robotaxi will be headed to New York City, but there is one huge thing that stands in its way: approval to test autonomous vehicles.

Tesla is expanding its Robotaxi platform across the United States as it currently operates in Austin, Texas, and the Bay Area of California.

The company has also been seeking approvals in several other states, including Nevada, Arizona, and Florida.

However, the company is also working to expand to major metropolitan areas across the U.S. that it has not explicitly mentioned, as it attempts to reach CEO Elon Musk’s goal of giving half of the country’s population access to the platform by the end of the year:

It appears New York City is next on the list, according to a job posting on Tesla’s Careers website.

The company says it is hiring a Vehicle Operator for Autopilot in Flushing, New York, a section of the borough of Queens. Queens is connected to Brooklyn and Long Island, so it seems more ideal than launching in Manhattan or the Bronx, where traffic is heavy and charging is not as readily available.

Tesla’s job posting states:

“We are looking for a highly motivated self-starter to join our vehicle data collection team. As a Prototype Vehicle Operator, you will be responsible for driving an engineering vehicle for extended periods, conducting dynamic audio and camera data collection for testing and training purposes. Access to the data collected is limited to the applicable development team. This role requires a high level of flexibility, strong attention to detail, excellent driving skills, and the ability to thrive in a fast-paced, dynamic environment.”

It also lists the hours of operation as Tuesday through Saturday or Sunday through Thursday, with its three shifts listed as:

  • Day Shift: 6:00 AM – 2:30 PM or 8:00 AM – 4:30 PM
  • Afternoon Shift: 2:00 PM – 10:30 PM or 4:00 PM – 12:30 AM
  • Night Shift: 10:00 PM-6:30 AM or 12:00 AM-8:30 AM

We wouldn’t count on New York City being the next place Tesla launches Robotaxi. According to a report from CNBC, a spokesperson for the NYC Department of Transportation confirmed Tesla has not yet applied for permits that are needed to operate its ride-hailing service.

For what it’s worth, it could just be the first step in Tesla’s plans. It also has Vehicle Operator job postings in other regions. Houston, Texas, as well as Tampa, Miami, and Clermont, Florida, are all listed on Tesla’s Career postings.

Tesla’s Elon Musk gives nod to Ford while acknowledging his influence on EVs

“Ford basically invented mass manufacturing of large, complex products. Everyone else copied.”

Tesla CEO Elon Musk gave a tremendous nod to Ford while also acknowledging his own influence on EVs and the automotive industry in general.

Yesterday, Ford announced its new manufacturing process for EVs, which was essentially a rebirth of its own production lines and plans for more affordable models to offer consumers.

It was important to recognize that Ford truly launched automotive manufacturing with its production of the Model T 122 years ago.

That’s exactly what Musk did in a response to Ford CEO Jim Farley:

In the over 100 years since Ford started producing vehicles, the company has had one significant fact go under the radar: it truly created a great process for building large, complex vehicles. It is something that many companies eventually adopted as the car industry took off.

Tesla is in a similar situation. It has used things like the Giga Press from the Italian company IDRA to create a better, more efficient, streamlined process for building cars.

It was able to use casting to eliminate a vast majority of parts from the Model Y, which not only helped increase manufacturing efficiency but also improved safety and structural rigidity. It truly revolutionized manufacturing for the company, and Ford said that it would adopt a similar mindset with its new EVs.

Yesterday, Doug Field, the Chief EV, Digital and Design Officer for Ford, and a former Sr. VP of Engineering for Tesla, said the company was taking the mentality that “the best part is no part.”

Musk acknowledged how far it has come and how it is influencing other car companies to do the same in terms of its production strategy:

Ford is using an “Assembly Tree,” which is essentially very similar to Tesla’s “unboxed production process.” In addition to the use of Gigacasting, which Ford is calling “Unicasting,” as well as the use of structural batteries, it is almost as if Tesla is having its own “Model T moment.”

Ford has been quick to adopt an EV mentality as it plans to transition its business over the next decades. It is working to prepare for the future of the atuomotive industry, and although it has adjusted its strategy, it can’t be denied that Ford is one of the legacy automakers taking this new chapter in cars seriously.

Tesla has one big bottleneck with its public Robotaxi launch, but it can fix it easily

Elon Musk plans for Tesla Robotaxi to be open to the public in Austin in September.

Tesla CEO Elon Musk said that the company’s Robotaxi program would open to the public in September, but there is one big bottleneck that would inhibit it from launching smoothly.

The thing is, it can be resolved in no time, and Tesla can fix it internally.

In Austin, the Robotaxi platform has been in operation since late June. The launch of the program only allowed a handful of privileged influencers and groups to access the driverless ride-hailing service, although it has expanded this group on several occasions.

It has also slowly added vehicles to the fleet, starting at 11 cars when it launched in June. There have been a few cars added, but Tesla has continued to prioritize safety, keeping its rider population and number of vehicles low for the time being.

However, this is going to cause quite a bit of a bottleneck in next month’s planned public launch, as there will be an open invitation for anyone and everyone to test out the Robotaxi platform in Austin.

Tesla CEO Elon Musk confirms Robotaxi is opening to the public: here’s when

Many people have been waiting for an invitation to ride in a Robotaxi, and Tesla has not been prone to give one to just anybody.

As that becomes a much larger number next month, Tesla is going to have to step up its Robotaxi fleet number, as well as its population of Safety Monitors, the riders that sit in the passenger seat to ensure everything goes smoothly.

While the geofence in Austin has roughly doubled in size twice during both of Tesla’s expansions of the service area, the company is still playing it safe with rider population growth, something that aligns with its focus on safety.

Musk said recently about the expansion of Robotaxi to customer-owned vehicles:

“As I said, we’re being paranoid about safety. But I guess next year is I’d say confidently next year. I’m not sure when next year, but confidently next year, people would be able to add or subtract their car to the Tesla, Inc. fleet.”

The Robotaxi fleet will, without a doubt, revolutionize the way people view ride-hailing. Tesla seems ready to open it up to the public next month, based on what Musk said, but some changes will have to occur to ensure it goes smoothly.
