New robotic gripper for automated apple picking developed

Washington state leads the nation in apple production, and in 2022, the industry contributed more than two billion dollars to the U.S. gross domestic product. Throughout Washington, farms employ anywhere from a dozen to hundreds of workers each year for orchard operations, including for pollination, pruning, flower thinning and fruit harvesting. With an and a decrease in migrant farm workers, however, farmers have struggled to meet their needs for workers during harvest season.

In recent years, researchers have started developing robotic apple harvesting systems, but the ones that have been developed are expensive and complex to use in orchards.

Ninatanta, who grew up in Yakima, Washington, picked fruit alongside his parents during his childhood. When he began his work with Luo on a robotic apple gripper, he had his parents videotape their work, so he could model his gripper on their handiwork.

AI discovers new rare-earth-free magnet at 200 times the speed of man

As some entities identify new (or at least overlooked) sources to meet the growing demand for rare earth materials, others are looking toward new tools. UK deep-tech company Materials Nexus announced on Tuesday that it has designed a new rare-earth-free permanent magnet with the help of its AI platform. It says the AI-driven discovery and development process was 200 times faster than the resource-intensive manual route, bringing new hope to an electrifying world with a growing appetite for powerful magnets.

With the world moving away from internal combustion engines and gradually embracing electric mobility, the demand for compact, high-power motors is rapidly rising. By far the most popular option in the automotive industry right now is the permanent magnet motor, which powers upward of 80% of modern electric vehicles.

Materials Nexus estimates that demand for permanent magnets will grow tenfold by 2030, in the EV industry alone. And it’s not just electric cars and trucks, either. Permanent magnet motors are in demand for many applications, including robotics, drones, wind turbines and HVAC equipment.

World’s largest robots will help airlines cut carbon emissions

A Norwegian startup is building massive AI robots to help airlines reduce their carbon emissions, save water, and inspect their planes in a fraction of the time it usually takes.

The challenge: The aviation industry is responsible for about 2.5% of global carbon emissions, and while sustainable jet fuels or electric propulsion systems could one day slash that figure, airlines can reduce their emissions right now — simply by cleaning their planes more often.

Washing an airplane’s exterior reduces air resistance, which means it can decrease the amount of jet fuel a plane needs to burn by up to 2% — while that’s not a huge difference, it can add up when you consider there are about 28,000 commercial jets in the global fleet.

Germany is No 1 in Europe for EV production, No 2 in the world

Germany’s automakers manufactured around 1.27 million BEVs and PHEVs in 2023, putting it at No. 2 behind China, but 2024 will be bumpy.

The German automotive industry association VDA says that 995,000 purely electric vehicles rolled off German assembly lines in 2023.

China dominates global EV production, but most of its cars are sold domestically. By contrast, 76% of German EVs are sold abroad. The US holds the spot for the world’s third-largest EV maker. And Germany, the home of key automakers such as Volkswagen, BMW, and Mercedes-Benz, leads Europe with more EVs produced than second-placed Spain (256,000) and France (225,000) combined.

World’s heaviest soaring bird inspires wind power design

When placed at the tip of a turbine blade, the c-shaped “winglet” inspired by the condor reduces drag, potentially increasing the turbine’s efficiency by up to 10% in optimal conditions, according to a study published in the journal Energy.

The wings of soaring birds have also been adapted for use in commercial and military aircraft around the world to increase their lift, says co-author Brian Fleck, a professor of mechanical engineering and expert in fluid dynamics.

“We used to have airplanes with straight wings,” says Fleck. “Now we see them with the tips curled up, and there’s a reason for that.”

In a world first, China installs an 18 MW offshore wind turbine

China has installed an 18-megawatt (MW) offshore wind turbine – the world’s largest by power rating – in Guangdong province.

State-owned power generator manufacturer Dongfang Electric Corporation completed the installation of the massive wind turbine at a coastal test base in Shantou on June 5.

China’s 18-MW offshore wind turbine has a 260-meter (853-foot) rotor diameter and a swept area of 53,000 square meters (570,487 square feet) – equivalent to 7.4 standard football fields.
