Abstract
The control of a helicopter is complex, and includes the interaction of forces and the balancing of them. Although a stable condition can be achieved with sophisticated control system, good mechanical design can reduce the problem of instability of a helicopter. One of the designs is the coaxial types of blade system. Nevertheless, a good control system is still needed since a helicopter control involves many parameters. PIC16F876A microcontroller has been used to measured the input from sensor, do the calculation and control the actuators). In this project, ultrasonic sensor is used to control the height of the helicopter. The force that been produce by the helicopter must be the same to make sure that the helicopter is stable.
