Abstract: With the help of an Arduino Uno microcontroller, TCS3200 Color Sensor, SG90 Tower Pro Servo Motor, and other electronic components, a color sorting robot is built. The system can quickly sort the objects into the appropriate color stations based on their colors. This technology can address issues that arise in the food sector, such as the separation of rice, coffee, and other cereals. The accuracy of color sorting by an operator is very low in the current business due to the human eye’s limited response time. A servo motor is employed to replace the operator and boost color sorting accuracy in order to ensure an innovative system. This research presents a novel method for continuously identifying and classifying things into the intended location. The light intensity test findings indicated that the procedure has been performed thousands of times without system failure throughout the implemented test, which was carried out as a system overview of color sorting movement.

The capacity to discriminate between colors is crucial for human survival because it allows us to visualize changes in our environment and choose other methods of human interaction or communication [1]–[3]. Furthermore, intelligent machines are given the power to distinguish, sort, and organize by modifying the capacity of color capture. The system uses sensors to determine an object’s color, which are then used to send data to an Arduino Uno, which then modifies a servo motor. To move it left and right, it may be found directly behind the ball slider [4]. The slider travels at an angle of 55°, 60°, or 180° depending on the color of the item when color is detected. The stations are, respectively, red, green, and blue. The slide returns to its default angle position after each ball placement and stays there until the next color ball is placed. Numerous academics have attempted to employ various programming techniques over the years to construct intelligent robots that could do specific tasks or accomplish goals[4]. The construction method discovered by authors in [5]–[9] has proven to be one of the newest technologies that can be applied to house private indoor robots. It follows its owners about and assists them when necessary. In other circumstances, the interactions of a small number of robots are required to complete a specific
