Studies on Automatic Traveling Control of Riding-type Rice Transplanter (Part 1)

Field Performances of Main Sensors

Abstract

The development of automatic traveling control system was tried to improve the straight driving of riding-type rice transplanter. An acceleration sensor and an angular velocity sensor were used, and their field performances were discussed. On flat fields, the acceleration sensor detected forward velocity with high accuracy, but on puddled fields errors broke out due to the effect of longitudinal inclination of the machine. Even on puddled fields, angular ranges obtained from the angular velocity sensor agreed with the actual fluctuating velocities in running direction by using a suitable amplifier and a suitable bandpass filter.
