Abstract-In this modern era, technological development lead the creation of sky scraper buildings and dwellings which increase risks of losing life due to natural and manmade disasters. Many people died by trapping under debris as their presence cannot detect by the rescue team. Sometimes, it is impossible to reach in certain points of the disasters in such calamity hit zones. The situation is worst for developing country because of low quality design and construction. This paper presents a way to find lives in debris using cell phone controlled rocker-bogie suspension type rover with a scooping arm. It has a wireless thermal camera with raspberry pi which transmits live video to a nearby laptop with a range of 100 feet. The scooping arm is attached to the rear portion of the rover and a motor controls the scooping operations using Bluetooth interfaced with Arduino.
Keywords: Rocker-bogie rover, Thermal camera, scooping arm, Arduino, Raspberry pi.
I. INTRODUCTION
A. Introduce of the Rocker Bogie Suspension
Since 1960’s many planetary explorations have been developed. The Rocker-Bogie system is the suspension arrangement used in the Mars rovers (mechanical robot) for both the Mars Pathfinder and Mars Exploration Rover missions. It is currently NASA’s favored design [1].
The term “rocker” comes from the rocking aspect of the larger links on each side of the suspension system. These rockers are connected to each other and the vehicle chassis through a differential. Relative to the chassis, when one rocker goes up, the other goes down. The chassis maintains the average pitch angle of both rockers. One end of a rocker is fitted with a drive wheel and the other end is pivoted to a bogie.
