Design and Fabrication Semi-autonomous Search and Rescue Robot using Rocker Bogie Mechanism

Abstract

In this modern period, technical advancement has resulted in the construction of skyscraper buildings and houses, increasing the risk of death from natural and man-made calamities. Building collapses and fires are a common risk for first responders around the world and attempts to enhance the safety and efficiency of search and rescue operations are ongoing. Nowadays mobility designs are very complex with complex designs and structures using many wheels or legs such complex mechanism can cause mechanical failure in harsh environment thus a six wheeled rocker bogie robot capable traversing rough terrain is useful which uses mobility suspension system which is of high degree. The main feature of rocker bogie design which is drive train simplicity as it uses only motors for mobility. Motors are placed inside the casing where thermal vibration is minimum, and reliability and efficiency are increased. In this robot we use 6 wheels as few obstacles on the terrain need both front wheels of robot to climb. There were many experiments in agricultural land, rough roads. Inclined stairs, obstacles surfaces. All these experiments finally concluded that rocker bogie can achieve distance traverses on field.
