由于无人机能够在危险和敌对的环境中执行期望的工作，同时能够保证执行任务人员免受危险的威胁，因此其军事应用价值越来越高。无人机的尺寸越大，则可靠飞行时间越长、载荷平台的效费比越高、还能挂载更多的武器。无人机已经逐渐发展成为必不可少的军用装备。

该项目面临的问题是，小型无人机是否还具有军事和商业/机械应用的价值。有人提议，小型无人机可服务于更具策略性的行动，例如，寻找作为敌方阵地的村庄或建筑物，以及完成小规模的运输任务以满足不同企业和营销工作的需要。为了挑战这个问题，本文考虑了各种无人机外形，最终设计了一个四旋翼无人飞行器。在这个项目中，最主要的任务是建立一个可以由直接飞行控制器控制的四旋翼飞行器。由于高有效载荷的限制，本无人机可用于运输，还可以用于外部观察和监视。

The military utilization of Unmanned AerialVehicles (UAVs) has improved effectively day by day due to their capacity tocarry out the desired work in hazardous and hostile environments while keepingtheir human administrators at a protected distance. The bigger UAVs likewisegive a reliable long span, cost effective platform for observation and inaddition weapons. They have been developed to be transformed into an imperativeapparatus for the military. The question postured for the project was whethersmall UAVs additionally had utility in military and business/mechanicalapplications. It was proposed that smaller UAVs can serve more strategicoperations, for example, seeking a village or a building for adversarypositions and in addition for completing little scale transportation andconveyance meets expectations in different businesses and marketing endeavors.To accept this suspicion and considering various UAV outlines it was chosen tooutline and create a Quadcopter. In this project the primary point is to buildup a quadcopter that can be controlled by a straightforward flight controller.With a high payload limit this can be utilized for doing transportation and inaddition outside observation as well as surveillance.
