The device received praise from a Chinese Foreign Ministry spokesperson. 
According to a report posted on the official WeChat account of Hangzhou, an orange lifebuoy took off from the shore during the drill, flew toward a person who had fallen into the water, and landed on the water surface. Even when the person climbed onto it, the device remained stable and continued to float.
Minutes later, rescuers arrived and brought the person to safety. The lifebuoy then took off again and returned to its original location.
The device, officially called an AI intelligent flying rescue robot, is designed to provide rapid assistance in open waters where rescue boats may take time to arrive. Equipped with an autonomous navigation system, it can fly to people in distress, provide buoyancy support, and return automatically after completing its mission.
The drill featured multiple water rescue scenarios and tested several intelligent rescue technologies. Drones were used to drop inflatable lifebuoys above people in distress, which quickly inflate upon hitting the water to provide temporary buoyancy.
Another system combined an unmanned boat and drone for rescue operations in dangerous waters. The drone searches and locates people in need, while the boat navigates autonomously to assist the rescue. The drone can also provide lighting for nighttime searches, according to the report.
Chinese Foreign Ministry spokesperson Lin Jian highlighted in a social media post on August 14 that the AI-powered device is "technology that could help save lives."

。    DETROIT -- Ford is recalling more than 238,000 Explorers in the U.S. because a rear axle bolt can fail, potentially causing a loss of drive power or allowing the SUVs to roll away while in park.The recall comes after U.S. safety regulators opened an investigation into the problem after getting two complaints that repairs didn't work in two previous recalls this year and in 2022.Affected are certain Explorers from the 2020 through 2022 model years. The National Highway Traffic Safety Administration says in documents posted Friday on its website that the rear axle horizontal mounting bolt can fracture and cause the driveshaft to disconnect, increasing the risk of a crash.Dealers will replace a bushing and the rear axle bolt. They also will inspect the rear axle cover for damage near the bolt hole and replace the cover if damage is found. Owners will be notified by letter starting Nov. 6.Ford said in documents that it knows of 396 reports of rear axle bolt failures, and fewer than 5% caused loss of power or let vehicles roll while they were in park. The company says it’s not aware of any crashes or injuries. NHTSA opened its investigation in June after getting complaints alleging loss of power due to failure of rear axle bolts even though the Explorers had received repairs under the previous recalls. Ford's remedy was to update software that automatically applied the parking brake to keep the vehicles from rolling away. But the agency said in documents that there was no remedy addressing the failed axle bolt. Ford said Friday that it was replacing axle bolts under service campaigns before the latest recall.。
