Remote And Voice Controlled Surveillance Robot With Multimodal Operation

Robotics has been a staple of cutting-edge fabricating for over 50 years. As robots and their fringe hardware become more complex, well-grounded, definitive and miniaturized, these frameworks are progressively being used for inspection, monitoring & intelligence purposes. The focus of this project is to design a model of an Android controlled robot vehicle that plays out a different work to give an extremely incredible and adaptable robot while likewise decreasing the equipment utilization however much as could be expected. In this venture, Arduino Nano is utilized as a primary part, to which the wide range of various parts are interfaced. This paper presents a model an Android-driven Arduino robot which can detect gas, smoke, check temperature, humidity and avoid any obstacles. The system is implemented using Arduino Nano, NodeMCU, Ultrasonic Sensors, Voltage regulator. Furthermore, a combination of Temperature sensors & Gas sensors used to provide domain-sensing along with the navigation in an unknown environment by avoiding collisions, which is a primary requirement for any autonomous mobile robot.
