Today, robotics play a vital part of the evolving technology used for security, surveillance and military etc. It is also very prominent among the people who develop robots as their hobbies. It is even used in schools as part of the academic curriculum. This report discusses a robotic prototype called ‘LAW Warrior’. It is designed and developed for purposes such as perimeter surveillance, campus security, military or even can be deployed in the debris due to any natural disasters such as earth quake. The whole purpose of this project is to make use of the current technology and develop an efficient robotic platform which can be easily operated by people. As the name consists ‘LAW’ which stands for Land, Air and Water, the robotic prototype can be deployed in land, air and/or water. The technology used for this robot consists of many which include autonomous GPS activity(with on board GPS module), Arduino powered microcontroller and motor controller, XBees for wireless transmission using Zigbee protocol, USB storage for logging and retrieving GPS information, Sound Sensor for detecting suspicious activities, Lithium Polymer battery as the main power supply, Servos, Headlights with adjustable focus mechanism, Camera for real time visuals, Ultra-Sonic sensor to prevent/cross-check object collision, Minibot for maneuvering in the air and lakes/rivers, Speech recognition mechanism with set of commands(passwords), Graphical User Interface(GUI) for servo, camera(color , face and motion tracking) and sensor feedback, mobile operation through commercially available android app and radio controllers to operate the main chassis and the Minibot. Future experiments could explore combining different modules (GPS, Mircrocontroller, Motor controller) into one single module. The GPS module can be replaced with more powerful one as this helps to get more accurate GPS coordinates. Head light adjustable (manual) focus can be made wirelessly adjustable, Camera module and bluetooth module can be improved/replaced with alternative technology so that data can be transmitted for long range. Whole main chassis can be made water-proof so that it can run on/through water surface. Minibot can be improved with more powerful rotors and can be made autonomous through vision and/or GPS.
