It has long been a problem that it’s very difficult to search for those who are trapped or buried in the earthquake. It’s very difficult for firemen to search for trapped people in the earthquake. They are often very aimless. Meanwhile, the trapped people are unable to call for help. SOS Ball is designed to solve this problem. As we all know ball is easy to tumble through interspace. There is G-sensor and GPS inside. When the ball hit the ground, it lights, making it easier for people to find. After pressing the button, the ball will send signals. Meanwhile the firemen are detecting by radar and locate it efficiently.
