Abstract— Robotics has been a staple of current carrying conductor placed within an external advanced manufacturing for over half a century. As magnetic field experiences a torque or force known as robots and their peripheral equipment become more Lorentz force. Advantages of a DC motor include low cost, sophisticated, reliable and miniaturized, these systems high reliability, and simple control of motor speed. The driver are increasingly being utilized for military and law used for DC Motors is L293D. The Device is a monolithic enforcement purposes Mobile robotics play an integrated high voltage, high current four channel driver increasingly important role in military matters, from designed to accept standard DTL or TTL logic levels and patrol to dealing with potential explosives. “With suitable drive inductive loads (such as relays solenoids, DC and sensors to perform different missions, mobile robots are stepping motors) and switching power transistors. This operated remotely for reconnaissance patrol an operator. project makes use of a micro controller, which is WIFI technology aims to exchange data wirelessly at a programmed, with the help of phyton instructions.

3) Raspberry pi The Raspberry Pi is a remarkable device: a fully functional computer in a tiny and low-cost package. Whether you’re looking for a device you can use to browse the web or play games, are interested in learning how to write your own Fig: Block Diagram of Existing System programs, or are looking to create your own circuits and physical devices, the Raspberry Pi – and its amazing IV.

Raspberry Pi Foundation, had little idea that it would prove provide supply to motors. A single L293D contains Two so popular: the few thousand built in 2012 to test the waters H Bridge to rotate the motor in both clockwise and were immediately sold out, and millions have been shipped anticlockwise direction. all over the world in the years since. These boards have found their ways into homes, classrooms, offices, data centres, factories, and even self-piloting boats and spacefaring balloons. Various models of Raspberry Pi have been released since the original Model B, each bringing either improved specifications or features specific to a particular use-case. The Raspberry Pi Zero family, for example, is a tiny version of the full-size Raspberry Pi which drops a few features – in particular the multiple USB ports and wired network port – in favor of a significantly smaller layout and lowered power needs. Raspberry Pi models have one thing in common, though: they’re compatible, meaning that software written for one model will run on any other model. It’s even possible to take the very latest version of the Raspberry Pi’s operating system and run it on an original pre-launch Model B prototype. It will run more slowly, it’s true, but it will still run. Throughout this book you’ll be learning about the Raspberry Pi 3 Model B+, the latest and most popular version of the Raspberry Pi. What you learn, though, can be easily applied to other models in the Raspberry Pi family, so don’t worry if you’re using a different version. Fig: Schematic of Proposed System

VIII. CONCLUSION Fig: Robot equipped with all components The proposed system is aimed towards the welfare of our infantry and the surveillance of warzone areas to The complete hardware of robot equipped with solar panel minimize the causalities to a great extent. It detects all metal objects like land mines using a metal detector. Our system will also be able to detect smoke and fire and take evasive action. It can measure infrared (IR) light radiating from objects in its field of view using the PIR sensor and thus detect any heat radiations emitting from humans or animals alike. The robot can be manually controlled but it will be able to take precautionary measures to protect itself and remain undetected. Hence, our system is sure to create a revolution in its own field and ensure complete support from people of different societies.
