Most existing robots designed to move on the ground rely on either wheels or legs, as opposed to a combination of the two. Yet robots that can seamlessly switch between wheeled and legged locomotion could be highly advantageous, as they could move more efficiently on a wider range of terrains, which could in turn contribute to the successful completion of missions.
US firm unveils Iran’s Shahed-style kamikaze drone with 100-pound payload power.
Alabama-based drone manufacturer Griffon Aerospace has unveiled its latest unmanned aircraft system, the MQM-172 Arrowhead, a drone designed to operate as both a high-performance target platform and a configurable strike asset.
Daniel Beck, Airworthiness Manager and Program Manager at Griffon Aerospace, said in a social media statement that the Arrowhead is developed to provide customers with a flexible, dual-role system that can adapt to changing mission demands.
100x larger hydrogen-rich hydrothermal system beneath western Pacific seafloor discovered.
Researchers revealed that the Kunlun hydrothermal field—a tectonically active site roughly 80 kilometers west of the Mussau Trench on the Caroline Plate—comprises 20 large seafloor depressions (some exceeding one kilometer in diameter) clustered together like a pipe swarm, a group of vertical or steeply inclined cylindrical rock structures that funnel liquid or gas from Earth’s interior.
The total area is 11.1 square kilometers, i.e., over a hundred times larger than the Lost City, a unique deep-sea hydrothermal field located on the Atlantis Massif, a section of the Mid-Atlantic Ridge.
“The Kunlun system stands out for its exceptionally high hydrogen flux, scale, and unique geological setting,” said Prof. SUN Weidong, the study’s corresponding author. “It shows that serpentinization-driven hydrogen generation can occur far from mid-ocean ridges, challenging long-held assumptions.”
98% reliable, guided rocket that hits target with perfection to get production boost.
GMLRS, also known as the “70-kilometer sniper rifle”, is an all-weather, precision-guided rocket. The system offers higher accuracy, reducing the number of rockets needed to defeat targets.
Lockheed Martin claims that the MLRS Family of Munitions (MFOM) includes a variety of precision-strike rockets and missiles, with on-going evolutionary development to meet the needs of the warfighter. These combat-proven low-cost, low-risk rounds greatly reduce collateral damage and provide tremendous capability and flexibility in addressing today’s threats.
There are multiple GMLRS variants, according to the company. Its GMLRS Unitary round integrates a 200-pound unitary warhead, providing precision strike for point targets. The Unitary variant has a range exceeding 70 kilometers.
Scientists discover oxygen ‘breathing’ crystal that could transform clean energy tech.
Researchers have created a crystal that can repeatedly absorb and release oxygen at low temperatures.
