Modify a RC car to handle three tasks: self-driving on the track, stop sign and traffic light detection, and front collision avoidance.
The system consists of three subsystems: input unit (camera, ultrasonic sensor), processing unit (computer) and RC car control unit.
A Raspberry Pi board (model B+), attached with a pi camera module and an HC-SR04 ultrasonic sensor is used to collect input data. Two client programs run on Raspberry Pi for streaming color video and ultrasonic sensor data to the computer via local Wi-Fi connection. In order to achieve low latency video streaming, video is scaled down to QVGA (320×240) resolution.
