Abstract

The purpose of this study is to analyze load of electric crawler type weeding robot. Driving tests were carried out in asphalt and paddy field condition. Load data was measured using CAN Bus. Driving tests were conducted to measure the motor current, motor torque, battery SOC and motor speed. As a result of the driving test, average motor current and motor torque values on the asphalt were 5.7 A and 3.5 Nm, respectively, whereas the average motor current and motor torque values ​​on paddy field were 10 A and 5.4 Nm, respectively. The load analysis on the electric crawler type weeding robot is used in this study to introduce the electrification of various small agriculture machines. In future studies, it is necessary to perform load analysis and power transmission system verification during the weeding operation in the working environment.
