Internet based Defence Surveillance Robot to Prevent Intruder Activities and Auto Combat System using SONAR Technology

Sound Navigation and Ranging (SONAR) is a device that uses radio signals of sound to communicate or detect things such as troops and tanks (typically submarines, for submarine guidance). Sonar is often used to describe equipment that generates and collects sound. Sonar uses echoes. Whenever a living creature or device makes a noise, it emits sound waves into the environment. Nowadays, most Defense Department uses robots to carry out risky missions that soldiers cannot perform. These defensive robots often use an integrated system consisting of video screens, sensors, a laser gun, a metal detector, and cameras. The Defense robots' forms also change depending on what they are used for. The brand-new system that is being proposed uses a wireless camera to find intruders (unknown people), and it will work with integrated systems. This proposed study detects things within a small range and displays information about the object and its behavior on an LED screen. It also shows real-time footage of that tracking system through IOT. This work aims to develop and construct an automated object tracking and destruction system. The target destruction system moves along the object's path, sending it away once found. When an object tracking system detects a target, it continually monitors it.
