Structural Design of Robot Applied in Post-Earthquake Relief

In order to enhance the ability of the rescue robot, and to accomplish a rescue mission in special environment, variable pitch crawler-type robot is designed. The structural concept of the new type of variable pitch has been proposed and designed, and this can help to improve the robot's adaptive capacity to complex environment. Then the varying pitch structure has been designed using pneumatic devices, it can ensure simultaneous operation of the right and left wheel at constant speed, and enable the robot to move nimbly through a tight space. The new crawler-type running gear strengthens the security and the stability of the complete system.
