Scientists at Purdue University have developed a mobile docking station that not only stops and charges these machines, but also exchanges their data at the same time, providing them with a way to run for a long time without too much human management. < / P > < p > we have seen that the development of UAV mobile charging stations can greatly extend their service life, and scientists from Purdue University are looking for similar solutions for AUVs. Given the marine environment, this clearly presents another challenge, but the team found inspiration in a modern home appliance. < / P > < p > & quot; there is an autonomous vacuum cleaner, such as the Roomba, which normally vacuumes and cleans normally. When its battery runs out, it will return to its charging station via autonomous navigation to complete charging, said Nina mahmoudian, an aerospace engineer who led the research. &That’s exactly what we’re doing, but the difference is that the environment is more challenging. &However, unlike robotic vacuum cleaners and unmanned aerial vehicles, underwater vehicles cannot rely on typical communication signals such as GPS or medium and short wave radio once they dive below the water surface. This means that they usually need to follow a pre programmed path and return to the ground once the battery runs out, and human processors retrieve their data and charge the battery. < / P > < p > & quot; it’s very expensive and limits the amount of time these robots spend performing tasks, mahmoudian said. < p > < p > mahmoudian’s solution is an algorithm driven mode, which reprogrammes the robot’s path during the operation of the robot, so that it can connect with the service terminal device to achieve the purpose of charging or transferring data. The team demonstrated the system through a short-term exercise in Lake Superior and hopes to launch a new version with multiple mobile service terminals. < / P > < p > according to the researchers, the portability of the service dock means it can be used in a variety of scenarios. One of the more imaginative examples is sending it on missions to explore distant worlds, such as Saturn’s moon Titan, which contains lakes scientists would like to investigate one day. The system can be used anywhere, says mahmoudian. &Robots on land, in the air or at sea will be able to operate indefinitely. Search and rescue robots will be able to explore a wider area. They will enter the Arctic to explore the effects of climate change. They will even go into space.
