A Control System of Velocity for Rice Sowing Robot in Mud Rice Field

Abstract

This paper proposed A control system of velocity for rice sowing robot in mud rice field was designed and constructed. The speed of the tractor was fixed at 2 km/hr, because provided the distance between drops at 10cm. The change in speed is necessary to design the tractor in the change of throttle bar to respond to the movement as desired. Design and analysis results in case of 0-60 mm position in 120s period provided low overshoot at about 0.0329%. The increase rate of the accelerator pedal was at 0.1667 which allowed speed of the tractor close to the set speed as in the test. And, results of the test in actual operating conditions of accelerator pedal control response indicated that the appeared velocity set on dry soil was lower tolerance for mud due to the nature of the dry soil caused lower change of speed.
