A remote surveillance vehicle powered by monocrystalline solar panels for defence applications

In the present scenario, surveillance is a key issue in the defense field. The surveillance is carried out mainly using the manpower. The main drawbacks of the system are disoperation or loop hole in the process of surveillance due to human negligence. Even vigil surveillance could lead to loss of human life in case of combat. Human life is very precious and hence machines can be used as a shield for human life. The ultimate solution is to carry out surveillance using an unmanned vehicle. This project aims to develop a remote surveillance vehicle which is powered by monocrystalline solar panels which has the maximum efficiency in all type of panels and being operated with mainly two parts, first one is the RF transmitter which will be in the hands of the person operating the vehicle from a remote and safe location. The second one will be the RF receiver which will be fitted in the vehicle. The vehicle is a prototype having four special geared motors with higher torque, fitted in each wheel controlled by a relay unit. There are four relays, each for one motor. The supply to the relay unit is being controlled by the controller unit (ATMEGA AVR 8535). The controller is being programmed with an embedded C++ using an ATMEGA AVR 8535 programmer. The power supply to the vehicle has being provided by using batteries which are being charged using Solar Panels with Maximum Power Point Tracking (MPPT) algorithm (P&O method). The MPPT is also programmed and embedded in the ATMEGA 8535 programmer. Bio sensing camera can be fixed and better implementation for the surveillance can be done as the future scope.
