Abstract
Robots are nowadays most oftenly used in the field of agricultural areas, one such robot is color sorting robot which is costless, fastest and most valuable in terms of saving money and labor. Color sorting robot is used to sort grains and fruits of different size and color.The goal of this undertaking is to outline a productive, microcontroller based project that get right sorting of items and put it down at opportune spot to upgrade the profitability, minimizing the expense of the items and diminishing human oversights. In this system the TCS34725 color sensor is interfaced with the Raspberry Pi A+ board on its 2nd I2C interface channel, running on Linux OS. The values are read using python script by calling the python I2C libraries. The color sensor requires a light source, white SMD LED to illuminate the sample. A low cost approach has been used to sense the size of the sample object, wherein the requirements of the object should be opaque. The circuit is realized using a set of comparators – 8x LM324 for each axis, and 2x CMOS Decade counter CD4017 to generate scanning in XY axis. The circuitry is controlled by Microcontroller (AT89S52) and is interfaced by its UART to the Raspberry Pi A+ processor board. The communication is handled in high level by the pySerial libraries. Based upon the detection, the robotic arm moves to the specified location, releases the object and comes back to the original position. Thereby eliminating the monotonous work done by human, achieving accuracy and speed in the work. The system is fabricated and efficiently working for sorting of objects.
