Abstract

The aim of this research is to design and implement PIC based radio frequency wireless communication system of two axes Pan Tilt payload camera unit for UAV. Camera is used as a payload and two servo motors are used to adjust the camera positioner in two axes to take the desired photo. User interface program is designed by C language on personal computer and serial communication RS232 protocol is used for data communication between personal computer and microcontroller. SONY digital camera is used to take the desired photographs and store recorded data to its memory. Ultra High Frequency band radio frequency wireless transmitter and receiver pairs are used for data communication link between the ground station and the receiver on the vehicle. And they are Amplitude Shift Keying ASK type IC and transmission frequency is 433.92MHZ. The Futaba S3003 servo motors mounted on the payload are driven by PWM pulse related to the transmitted data from the transmitter in order to get the desire payload camera orientation. The control system is based on microcontroller PIC16F877A. The microcontroller CCS C language is used for this control system.
