INTERFACING CMOS CAMERA WITH ARM MICROCONTROLLER FOR SMALL ROBOTIC PLATFORM

This proposal presents an autonomous color tracking mobile robot with obstacle avoidance. The robot detects the object color through CMUcam2. CMUcam2 is a camera which comes with an onboard image processing capabilities and can be interfaced directly to microcontroller. The robot follows the object according to the algorithm that had been programmed. The heart of the system is Raspberry Pi. Raspberry Pi is a credit-card sized computer that is powered by ARM11. This device runs on Linux OS and can be programmed to do specific functions. It supports many environments such C, Python and many more. The interfacing between the CMUcam2 and Raspberry Pi is performed through serial communication. The robot is programmed with Linux as the OS and C language to do the algorithm. In this project, a simple image processing technique is employed to process the image. The robot should be able to detect a specific color and follow it.
