Abstracts: An ornithopter is a class of Miniature Aerial Vehicle (M.A.V). It has a flapping wing mechanism which do not need a propeller for creating thrust, its wings are capable of creating both lift and thrust as well. They could be used for applications such as aerial reconnaissance without alerting enemies, remote sensing using electromagnetic spectrum sensors, gamma ray sensors, biological sensors or chemical sensors, search and rescue operations, satellite augmentation systems, oil, gas and mineral mine exploration, law enforcement and disaster operations, digital mapping/planning land management, commercial aerial surveillance, ground transportation, monitoring and control, etc. Our basic aim was to design a new and a robust mechanism having minimum no. of linkages and mechanical complexity for ornithopters and then fabricate an ornithopter working on the same mechanism. We started searching for the literatures related to our basic aim. The search for the literature was an unending process during this project as many of the constraints came into light on a very later stage. While reviewing the literatures 8 flapping wing MAVs were evaluated from research organizations worldwide. The available mechanisms were studied and their advantages and disadvantages were enlisted which made it easy for us to know about the desired features of a mechanism. On a later stage the conceptualization of the mechanisms started and we succeeded in generation of 4 new mechanisms. These newly conceptualized mechanism were then studied and analyzed and the best mechanism of all 4 mechanisms was selected. The selected mechanism was then designed with perfect dimensions in a designing software.
