SDB solution for nautical charts in shallow waters

TCarta has introduced a new line of Satellite Reconnaissance Charts designed to complement official marine navigation maps in shallow waters. These digital maps, derived from recently acquired satellite imagery, adhere to International Hydrographic Organization S-57 and S-100 data model standards, mirroring the appearance and symbology of official navigation aids. The new products are particularly valuable for shallow water navigation, where official nautical map products, primarily designed for commercial shipping lanes, may lack detail. tcarta.com

China unveils first homegrown space mining robot

China’s first space mining robot has been developed by the China University of Mining and Technology (CUMT). It not only adapts to the microgravity conditions of space but also navigates the rugged, cratered terrain of asteroids. The prototype has now filed patents with relevant authorities and successfully cleared preliminary reviews, the report said.

Space mining robots are confronted with geological exploration and mineral collection on extra-terrestrial bodies, requiring essential drilling capabilities. Under Earth’s gravity, the robot’s own weight is sufficient to support the drill’s penetration. However, lunar gravity is only one-sixth of Earth’s, and asteroids often exhibit ultra-low gravity, posing significant challenges for drilling into their surfaces.

To address the problem caused by microgravity, inspirations were drawn from insect claw-and-spine structures, and equipped the robot with specialized clawed limbs. Its array-style claw design enhances adhesion and anchoring capabilities in microgravity, allowing the robot to stabilize itself for sampling while adapting its movement to terrain. www.globaltimes.cn
