Abstract:In order to design a WIFI remote control intelligent car , which has remote operation, follow, tracking , obstacle avoidance, video capture and video return function through the WIFI control, system overall design scheme on Android platform is proposed .A dual independent power supply is used to avoid the introduction of interference caused by the operation of the motor. The circuit design and anti-jamming solution of the DC motor drive module and the design scheme of the WIFI module are discussed.The communication protocol between the Android device and the microcontroller and the key modules of software design are introduced in detail including motor drive and PWM speed control module, and command decode module. The test results show that the system runs well, and under the control of the Android device, the car can realize the function of remote operation, automatic follow, autonomous tracking, automatic obstacle avoidance, video shooting and video return, to meet the design requirements, to achieve the desired goal.
