In this paper, a line tracing algorithm for a robot was developed. The line tracing algorithm uses the robot’s car attached camera to detect the black line. The steering angle of the robot car’s wheels is then adjusted according to the black line detected. The performance of the proposed algorithm was evaluated by using the simple line tracking. We found out that using this technique the robot car is having a smooth drive following the black line. This study involves both hardware and software: raspberry pi as the microcontroller for the hardware and C++ for the software.
This paper takes the wheeled line-tracking robot as the investigative object and the realization of intelligent control as the target, bases on SCM STC12C5A60S2, make the design of line-tracking robots soft hardware, and the line-tracking algorithm emphasis, presents a new method in PID control, and combining straight-line acceleration and channel bend modification, The experimental result shows that this line-tracking robot meets the design requirements with rapid moving and stability.
