Abstract
Based on the principle of crawler drive, this paper puts forward a crawler robot climbing stairs device that can have a ground walking, climb stairs and travel across the barriers, which is convenient for the elderly and the disabled to travel.While using built-in the rotation of the swing arm to achieve the effect of climbing stairs, the complex wheel climb building device and crawler drive technologies can effectively avoid the dangers of climbing stairs.The key technology in this paper combined the triangular frame and the center of gravity retaining device in order to require the stability of the stair climbing devices.In conclusion, the present invention is good at climbing stairs more than traveling, which has the higher comprehensive benefit.[1]
