Top 10 Construction Robots in Use Around the World

Robotics-Engineering-1

EETimes & DesignLines – Construction: no matter if it is residential, commercial, or industrial — is one of the most labor-intensive jobs on the planet. It’s also the least automated, but that is rapidly changing as more robots are entering the field due to labor shortages and the pandemic. Adaptation has always been on the front lines when it comes to new technologies. Like with nearly every industry, automated robots are being deployed to construction sites all over the world.

As their name implies, construction robots are automated machines that assist with surveying, erecting buildings, or demolition. While there is some fear that robots will replace workers, these robots are designed to work with humans, making their jobs more manageable and less hazardous in some cases.

Dominion files plans with federal regulators for 2.6 GW offshore wind project, largest in US to date

Dominion-Wind-Energy

UtilityDive – Dominion Energy has filed the construction and operations plan for its 2.64 GW offshore wind project, with construction expected to start off the coast of Virginia in 2024. The anticipated filing with the Bureau of Ocean Energy Management (BOEM) was made after Dominion completed construction of a 12 MW pilot offshore wind project in Virginia — the first offshore wind turbines approved by regulators in federal waters. The company expects the BOEM review process for the largest offshore wind farm in the country announced to date to take about two years.

The offshore wind generation capacity is a large component of the utility’s clean energy plan, to meet the state’s rigid decarbonization standards in the Clean Economy Act passed earlier in 2020. Pending approval of the project by the State Corporation Commission and federal regulators, the project would provide renewable electricity to power up to 660,000 homes upon completion in 2026.

FBI: White supremacists plotted attack on US power grid

FBI-Power Grid-Attack-Plot

WKRN.com (FBI) – MINNEAPOLIS (AP) — White supremacists plotted to attack power stations in the southeastern U.S., and an Ohio teenager who allegedly shared the plan said he wanted the group to be “operational” on a fast-tracked timeline if President Donald Trump were to lose his re-election bid, the FBI alleges in an affidavit that was mistakenly unsealed.

The teen was in a text group with more than a dozen people in the fall of 2019 when he introduced the idea of saving money to buy a ranch where they could participate in militant training, according to the affidavit, which was filed under seal along with a search warrant application in Wisconsin’s Eastern U.S. District Court in March. The documents were inadvertently unsealed last week before the mistake was discovered and they were quickly sealed again.

The teenager wanted the group to be “operational” by the 2024 election because he believed it was likely a Democrat would win, but “the timeline for being operational would accelerate if President Trump lost the 2020 election,” according to the affidavit. An informant told investigators that the teen “definitely wanted to be operational for violence, but also activism.”

Why Grid-Tied Solar Power Systems Are Recommended Over Other Solar Systems?

Off-Grid-Solar-System-with-Backup
by the 3 Phase Associates “TEAM”
Renewable energy and distributed energy resources (DERs) continue to flood the electric utility grid providing cleaner and more sustainable energy. As the traditional power grid evolves into a smarter electric grid, environmental regulations push for more cleaner renewable energy sources. Solar PV electric power systems are leading the path in this effort with improvements in technologies, efficiencies, and cost reductions. The grid-tied solar systems are gaining popularity and becoming more favored over other solar electric systems.

Self-healing material a breakthrough for bio-inspired robotics

Digital-Clocks-Self-Healing

Science News and Carnegie Mellon University – Many natural organisms have the ability to repair themselves. Now, manufactured machines will be able to mimic this property. In findings published this week in Nature Materials, researchers at Carnegie Mellon University have created a self-healing material that spontaneously repairs itself under extreme mechanical damage.

This soft-matter composite material is composed of liquid metal droplets suspended in a soft elastomer. When damaged, the droplets rupture to form new connections with neighboring droplets and reroute electrical signals without interruption. Circuits produced with conductive traces of this material remain fully and continuously operational when severed, punctured, or had material removed.

Applications for its use include bio-inspired robotics, human-machine interaction, and wearable computing. Because the material also exhibits high electrical conductivity that does not change when stretched, it is ideal for use in power and data transmission.

Researchers Create Lab-on-a-Chip for Quick Infection Testing

Infectious-Disease-Testing

All About Circuits – As the pandemic resurges in many parts of the world, researchers have found a way to bring the speed and accuracy of infection testing to mobile devices with a lab-on-a-chip.

A new lab-on-a-chip has been developed by researchers at Imperial College London who hope it can pave the way for low-cost portable diagnostic testing. The lab-on-a-chip (LoC) technology, known as TriSilix, is a “micro laboratory” that can reportedly perform a scaled-down version of the polymerase chain reaction (PCR) test on the spot, presenting its results in just a few minutes. PCR, which detects viruses and bacteria in biological samples, is usually performed in a laboratory, meaning that test results don’t become immediately available. 

Each LoC device contains a DNA sensor, temperature detector, and heater so that the testing process can be automated. According to the researchers’ published findings in Nature Communications, a standard smartphone battery is capable of powering up to 35 tests on a single charge.
