The key point of a cutting robot is a microcontroller. In other words, the cutting robot comprises an arduino board in the center of a driving part of the cutting robot, ultrasonic waves, and an infrared sensor based on MCU including ATMEGA128, arduino, etc. and of which the upper part is formed to cut an object. To control the cutting robot, a control unit will control an agricultural robot using the Bluetooth communication or WiFi network of a cell phone and the whole agricultural robot is controlled by unusual data and controlling items using an android application. Functions of the android application can be classified into an automatic mode, a manual mode, and a house mode. To control the cutting robot first, the robot is connected to the cell phone via the application using the Bluetooth communication and WiFi. Further, the cutting robot is designed to cut crops and mulching plastic sheets in a greenhouse by operating the automatic mode or the manual mode. In the case of operating the automatic mode, the cutting robot detects furrows in the greenhouse using the infrared sensor and recognizes the finish of the work if a value is higher than the input value in the MCU. For example, when the work for one furrow is finished, the cutting robot changes a direction at the end of the furrow to work for the next furrow referring to the figure 5. As for a method for changing a direction to the next furrow, if the value inputted in the MCU, the distance between the robot and a hill, is higher than the input value, the robot recognizes the finish of the work and changes a direction to the next furrow. |
