VTOL aerial robot for inspection of transmission line

Unmanned aerial vehicles (UAV) have a great potential for use as they increase the reach of terrestrial teams without the increased costs of using manned aircrafts. The greatest difficulty of employing airplanes UAVs are the need of landing runways. A UAV capable of landing, take off like a helicopter, and which has the same performance as an aircraft in horizontal flight eliminates this difficulty without losing in range. These aircraft known as VTOL (Vertical Take Off and Landing) exist in several possible configurations, however the tail-sitter is the one that has fewer moving parts, and therefore less mechanical complexity. The aim of this paper is present a design of a VTOL UAV for line inspection.
