The design of security robot
Abstract: Nowadays natural disasters occur frequently，faced with a complex situation we need to be transferred as soon as possible and rescue the injured. It is very important to research and design a rescue robot which can instead of rescue workers and work in hazardous environment.
This thesis introduces a simple design structure of crawler robot which has a certain carrying capacity and anti the impact. Crawler rescue robots can adapt to complex environments, under rugged road conditions can also work. By loading different sensors and machine hand on the robot moving system, enables rescue robot have different functions.
In this paper, the tracked robot of mechanical structure is simple and easy to disassemble and repair. The different point is that we placed the driver structure in the track so that it can save a lot of space to set bigger battery to extend the work time. We can also control both sides of the fin wheel robot to assist climbing, crossing barriers
