Military spying robot

The paper explains an RF (radio frequency)-based spying robot for wireless devices; it will help to investigate as per requirement. The proposed spying robot methodology can be controlled by an application that is running on an Android mobile to control the spying robot. The proposed method uses a Raspberry Pi 3B and different types of sensors for the purpose of investigation. It does so by transmitting control commands over Bluetooth, which are then received by the processor. The UART (Universal Asynchronous Receiver Transmitter) protocol can be used to establish a connection between the processor and the Bluetooth module. It can be used at the border to find hidden land mines and detect smoke. Liquefied petroleum gas, carbon monoxide, methane, alcohol, hexane, and benzine are among the different types of smoke that it can detect. It takes pictures of people, and if the face of the person can’t be verified, that data can be sent to the main office. If the face is not recognized as per the register data, the DC (direct current) motor moves in that direction and attacks the person. As per the received commands, the robot can be moved, and the necessary actions can be taken. The proposed work detects smoke, metal and unknown person using Raspberry pi and sensors.
