Introduction
A quad-copter, also called a quad rotor helicopter, is a
multi-copter that is lifted and propelled by four rotors. Quad-copters are
classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift
is generated by a set of revolving narrow-chord airfoils. Unlike most
helicopters, quad-copters generally use symmetrically pitched blades. Quad-copter
operated by thrust that produce by four motors that attached to it body. Quad-copter
has advantages over the conventional helicopter where the mechanical design is
simpler. Besides that, Quad-copter changes direction by manipulating the
individual propeller’s speed and does not require cyclic and collective pitch
control.
This project is to build a quad-copter that can lift up for
about 2kg load and can be controlled by controller wirelessly. This quad-copter
will reduce the burden on the residents of flats to lift the load for about 2kg
go up to their house. This greatly simplifies the user when their flats do not
have access to a lift. This quad-copter also can be use at the dangerous
environment such as in nuclear reactor or building on fire where can ease and
reduce the risk for the purpose of rescue or anything risky job.
