Embedded ultra-low power driver for a 7.2g helicopter and IrDA remote control

Student Projects

Abstract

In a previous project, a 7.2g helicopter made of carbon was designed and realized at the LAI. The goal of this project is to design and realize a tiny receiver and a remote capable of driving the helicopter from a distance of 2 to 4 meters. Challenges are here to make the receiver small and light enough to be embedded in the helicopter without disturbing the flight. Ultra-low consumption is also required. Both emitter and receiver will have to be designed and mounted by the student. The microcontroller is to be chosen in the MSP430F21x2 family. Well-known for their low-power consumption, they also possess an IrDA serial communication interface which will be used for a bi-directional communication between the helicopter and the remote. The remote will have to control 3 channels (lift, yaw and eventually pitch) and display the battery level of the helicopter.

Helicopter

A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.

Radio receiver

In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information.

Helicopter flight controls

A helicopter pilot manipulates the helicopter flight controls to achieve and maintain controlled aerodynamic flight. Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a deliberate way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades cyclically during rotation, creating differing amounts of lift (force) at different points in the cycle.
