UAV Advancement: From Increasing Endurance, Route Re-Plan and Collision Avoidance, to Safe Landing in Critical Conditions

Abstract

Unmanned aerial vehicles (UAVs), one of the fastest growing and the most emerging future technologies, is in demand everywhere, from using it as goods carrier to structural monitoring, from surveillance application to using it in the battle field, and in the battle field too, it varies from an attacker to an ambulance, depending on the circumstances. Also, according to the applications and operations, fixed wing and multicopter aircrafts are used. The ideas related to designing, materials, manufacturing, assembling, application, controlling, etc., keep on changing this technology, and for this reason, we have come so far from the start-up basic model. In spite of these sort of upgradation, there are still challenging problems which does not affect only one particular function, but it degrades the whole functionality of an overall, expected to perform well in its operation, UAVs. Some important drawbacks can be solved with the help of different technologies which in turn will be the possible solutions for our challenges.
