摘　　要：机器人的应用离不开传感器,传感器应用成为青少年教育中机器人的一个重要技术。如在循线机器人中,光电传感器能够识别地面的白色和黑色,以实现机器人沿着黑线前进的目的。最近几年随着科技的发展,颜色识别的应用场景越来越多,如解魔方机器人、追球机器人等就需要颜色的识别。用传统的光电传感器不能准确地识别彩色;而用摄像头识别技术又显得大材小用,同时青少年在技术上也不能灵活地驾驭。从能否用传统的光电技术设计一个颜色识别传感器的角度出发,利用物理光学知识和新兴的单片机技术,研究并设计了一款灵敏度高、可靠性强且体积小的颜色识别传感器。The application of robots cannot be separated from sensors,which have become an important technology for robots in youth education.For example,in a line following robot,photoelectric sensors can recognize the white and black colors on the ground to achieve the goal of the robot moving along the black line.In recent years,with the development of technology,the application scenarios of color recognition have become increasingly diverse,such as solving rubik's cube robots,chasing ball robots,etc.,which require color recognition.So,traditional photoelectric sensors cannot accurately recognize colors.However,using camera recognition technology appears to be a waste of talent,and at the same time,teenagers cannot flexibly control their skills.This article starts from the perspective of whether traditional optoelectronic technology can be used to design a color recognition sensor and utilizes physical optical knowledge and emerging microcontroller technology to study and design a high sensitivity,high reliability,and small volume color recognition sensor.
