Soryu-4 is a robot developed for Urban Search & Rescue missions.

It consists of an articulated body made of 3 traction modules, which allows Soryu-4 to move inside narrow environments, but also to climb obstacles 3 times its own height, and to move over unstructured terrain with ease. The mobility of Soryu-4 makes it an ideal choice for outdoor applications, where ruggedness and reliability are as important as mobility.

Soryu-4 can be customized depending on the needs of the mission. The version shown here has standard and thermal cameras for navigation and inspection, and also a sensor release mechanism equipped with a pack of sensors used to look for survivors inside collapsed structures.
