Earthquakes, fires, explosions and other natural and abnormal accidents cause debris and destruction of a site, after which the aid and rescue teams should help people who are in this area. Sometimes relief is inaccessible in some places. The environment that fires it and makes it difficult for the aid workers to make it difficult to make it difficult. Hence, aid robots come to the aid of the relief team to help reach the victims of the accident. Robots with an anti-fire and high-power body can be traversed as stairs and cross the obstacles to reach the accident points and send a picture of that area to the control unit. After seeing the images of the injured, the officers can make a decision on helping the area. So far, there have been many rescuer robots, the Sedra rescue boat known as a national rescue robot designed and built by the robotics team of the Sharif University of Technology. Despite its various features, the robot has many disadvantages, including weight and volume. In this dissertation, measures are taken to address the disadvantages of this robot. In the chapters of this thesis, after analyzing the Sedra's robot's robot, the rotary wheel is used instead of the rubber wheel's rubber technology. These changes reduce the weight and volume of the robot and improve the performance of this robot.
