Abstract
This study tried to explore the outcomes of color sensor under different circumstances. According to the rule of previous robot competition, robot had to detect assigned color ring first. Moreover, the robot had to find the right color ring and push the ring into score zone. The color sensor uses the LED light to obtain RGB value by means of reflection. It is not very easy to complete these two works at the same game. Previous color sensor RGB value settings may vary with different factors, for example light, distance and ring color. This study tried to explore possible factors which will interrupt the detection of color sensor.
It revealed that the RGB value is related to difference color light. Additionally, the lumen of LED and the distance of detection as well as the high of light source will influence the accuracy and precision of detection.
