This paper presents thoughts on legged walking robot for urban search and rescue (USAR) operations. Article discusses the importance of robotics applications for rescue operations. Main required characteristics of a robot for USAR are presented. Overview of proposed mechanical construction of body and legs, onboard equipment (camera, sensors, audio and communication equipment) is given. Main principles of graphical user interface and operational algorithms are presented. This paper is a preliminary work that describes main ideas and required features and is a basis for future research and development of a USAR walking robot.
