A camera mounted on the robot provides visual information to help the user control the robot remotely through any user terminals with Internet connections. The robot sends visual information to a server through a Wi-Fi network. The server transmits visual information to the user through the Internet. RF transmitter and RF receiver also used here to transmit and receive the command and data. Proximity sensor is used to detect the landmines. A six degree-of-freedom manipulator mounted on a four-wheeled robot base is used to remove the landmines. The battery gets electricity from atmospheric temperature using solar panel with MPPT. Robot can swap the dead battery with charged one by using manipulator. By using MPPT technique battery can get maximum electricity power from atmospheric temperature.

INTRODUCTION Robot systems have been widely used in military automation applications to provide safe working environments. Some researchers have developed surveillance robot systems for military security. A patrol robot system for military security is proposed to gather environment information and detect abnormal events. The authors p r esen t an intelligent landmine robot focusing on safety and security. There are also many robots developed for military service applications such as spy robot, soldier robot. The robot can provide visual information and dangerous situation detecting. The research work on a military assistant robot is introduced. The robot improves the ease and productivity of soldier’s activities. In order to realize reliable and flexible decision making, an inference mechanism is used by the robot to decompose higher level task specifications into primitive tasks. RF transmitter and RF receiver also used here to transmit and receive the command and data. In order to realize various functions such as locomotion, positioning, manipulation, and sensing, a great many motors and sensors are used in robot systems. The battery gets electricity from atmospheric temperature using solar panel with MPPT. Photovoltaic cells have a complex relationship between their operating environment and the maximum power they can produce. The fill factor, abbreviated FF, is a parameter which characterizes the non-linear electrical behavior of the solar cell. Fill factor is defined as the ratio of the maximum power from the solar cell to the product of Open Circuit Voltage V oc and Short-Circuit Current I sc . A load with resistance R=V/I equal to the reciprocal of this value draws the maximum power from the device. This is sometimes called the characteristic resistance of the cell. This is a dynamic quantity which changes depending on the level of illumination, as well as other factors such as temperature and the age of the cell. If the resistance is lower or higher than this value, the power drawn will be less than the maximum available, and thus the cell will not be used as efficiently as it could be. Maximum power point trackers utilize different types of control circuit or logic to search for this point and thus to allow the converter circuit to extract the maximum power available from a cell. In this paper, the design and implementation of a battery swapping and solar charging robot system are presented for military automation applications. A six degree-of-freedom manipulator is mounted on a four- wheeled robot base. The manipulator can remove the landmines. The robot sends visual information from a camera mounted on it to the server through the local Wi-Fi network. The server transmits the visual information to the operator. The operator can control the robot to move to the position where the want to detect. The rest of this paper is organized as follows. Section II introduces the overall architecture of the robot system. The system design is presented in Section III. The experimental results of the proposed robot system are given in Section IV. Concluding remarks and future work are given in Section V.
