Abstract

This study was conducted to ascertain factors and influences on the accuracy of the photoelectric sensor
of an autonomous robot.
We hypothesized that the recognition accuracy of the white run sensor is affected by the material of the
white line, the difference in color, the type of ambient light, and the distance between the sensor and
the floor surface. Therefore, these four factors were verified. The results showed that the accuracy was
not affected by the material or ambient light, and the color matched the reflection spectrum of the red
LED, with the highest value at 3.0 mm.
Unlike the hypothesis, there was no effect of external light, which was thought to be a factor interfering
with the accuracy, and there was almost no change in the material of the white line, and it was thought
that the closer the distance between the photoelectric sensor and the ground, the higher the value was,
but in fact 3.0 mm was found to be optimal.
We would like to make the most of these studies in our future development
