Abstract: An unmanned aerial vehicle also known as UAV is anunpiloted aircraft which can either be remotely operated or flown autonomously based on pre-programmed flight plans. Usually these types of vehicles are used in military applications for missions that are too dangerous for manned aircraft. They are also used in a growing number of civil applications such as aerial photography and the transport of various goods. The last decade has seen rapid progress in micro aerial robots, autonomous aerial vehicles that are smaller than 1 meter in scale and 1 kg or less in mass. Winged aircrafts can range from fixed-wing vehicles to flapping-wing vehicles , the latter mostly inspired by insect flight. Rotor crafts, including helicopters, coaxial rotor crafts,ducted fans, quadrotors and hexarotors, have proved to be more mature with quadrotors being the most commonly used aerial platform in robotics research labs.This paper focused on the development of a family of trajectories defined as a sequence of segments each with a controller parameterized by a goal state.This approach permits the development of trajectories and continous enabling aggressive maneuvers such as flying through narrow,vertical gaps and perching on inverted surfaces with high precision and repeatability.This design describes a flying quadrotor prototype of 750gms,38 cm diameter with on board altitude estimation and control that operates autonomously.The bot is designed to be controlled by PCB circuits with usage of microcontroller, actuators and sensors. The controlling programs are to be stimulated by MAT LAB/Arduino.This work will be useful in the field of Defence,Navigation,Automation and also could be a multi utility product.
