Takeoff and landing control using force sensor by electrically-powered helicopters

A takeoff and landing control of helicopters using a force sensor helicopter is introduced. The system consists of a small electrically-powered helicopter, a flight base under which the force sensor is set, and a helicopter control terminal which is connected to a system controller. When the helicopter stands on the base, the force sensor outputs data corresponding to the weight of the helicopter. As the operational voltage rises, the helicopter almost takes off from the base. Concurrently, the force sensor output closes to 0. It means that lift force related to force output becomes from 0 N to the value corresponding to the weight. This paper introduces the design process including system modeling and the experimental results
