Amid the festivities at its fall 2022 GTC conference, Nvidia took the wraps off new robotics-related hardware and services aimed at companies developing and testing machines across industries like manufacturing. Isaac Sim, Nvidia’s robotics simulation platform, will soon be available in the cloud, the company said. And Nvidia’s lineup of system-on-modules is expanding with Jetson Orin Nano, a system designed for low-powered robots — plus a new platform called IGX.

Isaac Sim, which launched in open beta last June, allows designers to simulate robots interacting with mockups of the real world (think digital re-creations of warehouses and factory floors). Users can generate datasets from simulated sensors to train the models on real-world robots, leveraging synthetic data from batches of parallel, unique simulations to improve the model’s performance.

It’s not just marketing bluster, necessarily. Some research suggests that synthetic data has the potential to address many of the development challenges plaguing companies attempting to operationalize AI. MIT researchers recently found a way to classify images using synthetic data, and nearly every major autonomous vehicle company uses simulation data to supplement the real-world data they collect from cars on the road.

This novel technology can be built in many ways, even like a snake.

The National Renewable Energy Laboratory (NREL) has revealed a breakthrough technology with wave energy. The lab claims that with this new technology, electricity can be produced from waves and even from clothes, and cars.

NREL — which specializes in the research and development of renewable energy, energy efficiency, energy systems integration, and sustainable transportation — has already taken out the patent of its unique distributed embedded energy converter technologies (DEEC-Tec).

“You could train your particular ‘tongue’ to know what one of these whiskies ‘tasted’ like, so that when the fake stuff came along it could identify it and when the real stuff came along it could confirm that it was the real stuff,” said Dr Alasdair Clark, the lead author of the research from the University of Glasgow.

Clark said the technology could be incorporated into a small, portable device and have a wide range of applications, from identifying poisons to environmental monitoring of rivers.

“Initially we thought of it more for sort of production line, quality control maintenance, [for example] if you are an apple juice company and you want to make sure that the apple juice you make on Tuesday is the same as the one that you made last week,” said Clark.

Electric vehicles have often been hailed as the future. Major motoring companies are aiming to produce nothing but electric vehicles in the future, and some aspire to hit that target by the end of the decade. Cars that are traditionally seen as so-called gas guzzlers — like pickup trucks, muscle cars, and hummers — all have electric equivalents. Governments, including the one running the United States, are improving infrastructure, offering tax incentives, and enacting policies aimed at getting more electric vehicles on the road. And modern-day industrial icons like Elon Musk, who obviously has a vested interest in the electric car’s success, constantly promote the concept. Musk recently published a tweet that likened internal combustion engines to the steam engine — an archaic method of producing mechanical power.

The loss of life would be equivalent to six planes, each carrying 200 passengers, killing everyone on board, every year.

Reducing air pollution from road transport will save thousands of lives and improve the health.

In our published research we evaluated the costs and benefits of a rapid transition. In one scenario, Australia matches the pace of transition of world leaders such as Norway. The modeling estimates this would save around 24,000 lives by 2042. Over time, the resulting greenhouse emission reductions would almost equal Australia’s current total annual emissions from all sources.

We also calculated the total costs and benefits through to 2042. Australia would be about 148 billion Australian dollars better off overall with a rapid transition.

A team at Los Alamos National Laboratory has developed a novel approach for comparing neural networks that looks within the “black box” of artificial intelligence to help researchers understand neural network behavior. Neural networks recognize patterns in datasets; they are used everywhere in society, in applications such as virtual assistants, facial recognition systems and self-driving cars.

“The research community doesn’t necessarily have a complete understanding of what neural networks are doing; they give us good results, but we don’t know how or why,” said Haydn Jones, a researcher in the Advanced Research in Cyber Systems group at Los Alamos. “Our new method does a better job of comparing neural networks, which is a crucial step toward better understanding the mathematics behind AI.”

Jones is the lead author of the paper “If You’ve Trained One You’ve Trained Them All: Inter-Architecture Similarity Increases With Robustness,” which was presented recently at the Conference on Uncertainty in Artificial Intelligence. In addition to studying network similarity, the paper is a crucial step toward characterizing the behavior of robust neural networks.

This is also the fastest IPMSM built with commercialized lamination materials.

Researchers at the University of New South Wales Sydney have developed a new electric motor that can clock 100,000 revolutions per minute. The high power density achieved as a result of this new design could help reduce the weight of electric vehicles (EVs) and thereby increase their range, a university press release said.

EV makers around the world have been looking for ways to address the range anxiety of their battery-powered vehicles. One of the options is to increase the size of the battery pack, which also increases the weight of the vehicle, creating more problems to solve.

China appears to be a leader in maglev technology and continues to find innovative ways to use it.

A car equipped with magnetic levitation (maglev) technology has been successfully tested on a highway in East China’s Jiangsu province, according to an article by China Daily.

Provincial transport authorities are testing a new highway lane for maglev cars. The experiment saw a 2.8-tonne car float 35 millimeters above the road and run smoothly on a highway without crashing or veering.

“We think that each car needs to sound for itself.”

It was roughly six years ago when Audi started designing bold soundtracks for its growing line of hybrids and EVs. Why did the 111-year-old carmaker need custom sounds for its forward-looking product line? It all comes down to one thing: electric vehicles are practically silent, even when traveling at high speeds.

Audi.

The idea of silent cars might seem exciting if you spend your days walking beside noisy urban streets, but quiet cars have a couple of drawbacks. For one thing, they’re dangerous to pedestrians and other drivers. That’s why most countries have a series of regulations that set acceptable ranges for the volume and pitch of the noises that EVs have made. Another down of noiseless EVs is the driving experience. A full-bodied roar makes driving more fun.
