Problems solved by technology

Since the detection characteristics of different grayscale sensors are not highly identical, there will be differences in the recognition of the same color. Therefore, it is not suitable for a large number of robots to process the grayscale sensor detection data with the same calibration results, otherwise it will lead to different robot colors. The difference in recognition ability is huge, causing product quality problems

Description

technical field [0001] The invention relates to a robot, in particular to a robot grayscale sensor calibration device. Background technique [0002] The grayscale sensor is a commonly used sensor for robots, and is generally used for robot color recognition, line inspection, etc. The grayscale sensor uses the principle that different color detection surfaces have different reflection degrees of light, and the photoresistor has different resistance values ​​for the light returned by different detection surfaces to detect the color depth. [0003] Grayscale sensors have an LED and a photoresistor mounted on the same surface. Within the effective detection distance, the light-emitting diode emits white light, which shines on the detection surface, and the detection surface reflects part of the light. The photoresistor detects the intensity of this light and converts it into a signal that the robot can recognize. [0004] A small educational and entertainment robot needs to be...
