Wireless multifunctional robot for military applications

This paper presents a modern approach for surveillance at remote and border areas using multifunctional robot based on current 3G technology used in defence and military applications. This robotic vehicle has ability to substitute the solider at border areas to provide surveillance. The robotic vehicle works both as autonomous and manually controlled vehicle using internet as communication medium. This multisensory robot used to detect human, bombs, harmful gases and fire at remote and war field areas. Conventionally, wireless security robot obsoletes due to limited frequency range and limited manual control. These limitations are surmounted by using 3G technology which has limitless range. This system also enhances the use of renewable resource of energy by equipping with solar panel. An autonomous operation is controlled by ultrasonic sensor and infrared sensors. Manual operation is controlled by DTMF decoder and cell phones used as video camera by initializing 3G video call and change the path of robot according to real time information of surrounding. This paper also illustrates the experimental results of tilt angle selection of solar panel and power consumption in automatic and manual mode. This robotic vehicle is designed for reconnaissance as well as surveillance under certain circumstances.
