Development of autonomous bio-production vehicle for agriculture.

The study was carried out to automate the operation of the 'Bobcat' tractor for the farming purpose. Bobcat tractor is a hydrostatic tractor that uses levers for steering, breaking and the forward and backward movements. Two set of screw shaft driven by car power window motor were used to move the two levers. The computer program was written to automate the movement of each lever. Bobcat tractor move straight forward when both levers move forward and vice versa. Bobcat tractor will turn left when only the left lever is moved forward and vice versa. The friction between the levers and the attachment was a major concern in this project. The bearing was introduced and the existence space between the levers and the attachment can solve the friction problem. Autonomous tractor increases the effectiveness of the field with little or no help of supervision.
