Design of Multifunctional Intelligent Car Based on Bluetooth Remote Control

Wireless remote control robot car could play a special role in the hazardous environment operations and search & rescue personnel. A multi-function smart car with Bluetooth remote control is selected as my graduation thesis subject. The design of the system hardware circuit schematic and PCB diagram is present in paper. The control system circuit is mainly consist of a STC12C5A60S2 MCU as the main chip, as well as a L293D chip for motor driving, a Bluetooth wireless communication module for remote control, an infrared photoelectric sensor module for object detection, an ultrasonic transmitter and receiver module for distance measurement. The smart car is implemented by the combination of the self-control circuit, the control program code and four-wheel car mechanical structure. Experimental tests showed that some functions such as Bluetooth wireless remote control, automatic obstacle avoidance, automatic tracking route, auto-sensing objects and auto-detecting distance were completely achieved in the smart car.
