Review on Sensor based Colour Sorting Robot for Candy Manufacturing

In this work, a new approach for high speed sorting of candy into desired locations is introduced. In this work color sorting of candy is done by detecting colour and the edges of given image which are of similar colours. The colour sensor TCS230 detects three colour red,green,blue and black(no colour). When there is no candy in front of the sensor it produces an output of 330Hz range frequency and when there is a candy it produces an output frequency of 7-14 kHz.The microcontroller can find the frequency of the output from TCS230. The output is obtained by sorting the color of candy depending on the frequency analysis of the output of the TCS230 sensor in the Conveyor system.This work focuses on literature review of sensor based colour sorting robot for candy manufacturing.
