The flight navigation strategy of moths can help drones to navigate unfamiliar and complex environments, say researchers who used real insect flight trajectories to develop decision-making programme for autonomous vehicles.
The researchers from University of Washington in Seattle and Boston University said that by using real data from animal flight paths, they can programme bio-inspired drones that will be able to navigate autonomously in cluttered space.
To understand how real moths plan their route, the researchers mounted 8 hawk moths on metal rods connected to a torque meter.
In front of each moth, they projected a moving forest scene created from beams of light for the moth to navigate.
They captured data from the moth flight and built a mathematical model to describe the moth trajectory through the virtual forest.
The flight data were translated into a decision-making programme that could be used to control a drone, said Loannis Paschalidis from Boston University and Thomas Daniel at University of Washington in the open-access journal PLOS Computational Biology.
They compared how the drone and the moth performed in simulations of the same forest layout, as well as new configurations with different densities of trees.
The researchers found that hawk moths mainly rely on the pattern created by the apparent motion of objects caused by their flight.
However, the flight programmes optimized for drones performed 60 per cent better in the simulated forest “because they also incorporated information about the exact location of objects in their surroundings into their navigational decisions”.
Although the researchers were able to optimize the strategy used by moths to improve performance in certain environments, the moths’ strategy was more adaptable, performing well in a variety of different forest layouts.
“The moth model performed best in dense forests, suggesting that hawk moths have evolved a flight strategy adapted to the thick forests they often encounter,” the authors wrote. (IANS)

Khadi is no longer a dull, drab fabric meant only for politicians' wardrobes. A fashion show organised by the Khadi Gramodyog Board as part of the Azadi Ka Amrit Mahotsav to mark the 75th year of India's Independence showcased the use of Khadi in traditional, as well as, contemporary and festive wear. From lehengas in resplendent Khadi silk to western clothes and casual wear, the models on Thursday night displayed new facts of the fabric.
Several well-known Indian designers including Ritu Beri, Farah Ansari, Rina Dhaka, Asma Husain, Aditi Rastogi and Himmat Singh showcased their designs. Gaurav Gaur directed the fashion show with clothes like lehengas, kurtis, kurta pajamas and partywear.
Lucknow's chikankari and silk artisans also participated in the event. A wedding collection in Khadi was the highlight of the show. "The show was based on the concept 'Khadi for nation, Khadi for fashion' and the fabric for all costumes was provided by Khadi Gramodyog Board," said a spokesman. (IANS/ MBI)

Intel saw its stock tumbling by more than 8 percent after the chipmaker said the industry-wide component shortage affected its PC chip business during the third quarter (Q3). Intel CEO Pat Gelsinger told CNBC late on Thursday that he didn't expect the semiconductor shortage to end until 2023. "We're in the worst of it now, every quarter, next year we'll get incrementally better, but they're not going to have supply-demand balance until 2023," Gelsinger was quoted as saying.
The company delivered its Q3 results with revenue up 5 percent (year-over-year) driven by strong demand in its DCG and IoTG businesses, despite the highly constrained industry-wide supply environment. "Q3 revenue was $18.1 billion slightly below our guide due to shipping and supply constraints that impacted our businesses," George S. Davis, Chief Financial Officer, said in a statement. He also announced plans to retire from Intel in May 2022. In the third quarter, the company generated $9.9 billion in cash from operations and paid dividends of $1.4 billion.

According to the company, the demand remains strong in its PC business with particular strength in commercial, desktop, and higher-end consumer notebooks. In an earnings call, Gelsinger said that the digitization of everything accelerated by the four superpowers of AI, pervasive connectivity, cloud to edge infrastructure, and ubiquitous compute are driving the sustained need for more semiconductors. "The market is expected to double to $1 trillion by 2030. In that timeframe, the market for leading-edge nodes will rise to be over 50 percent of the total, while the market for leading-edge foundry services will grow at twice the rate of the semi-industry overall," he envisioned.
PC demand remains very strong, and "We believe the 2021 TAM (total addressable market) will grow double digits even as ecosystem shortages constrain our customer's ability to ship finished systems," Gelsinger added. "Customers continue to choose Intel for their datacenter needs and our third-gen scalable Xeon processor Ice Lake has shipped over 1 million units since launching in April, and we expect to ship over 1 million units again in Q4 alone," he informed.
