Development of autonomous bio-production vehicle for agriculture

The study was carried out to automate the operation of the ‘Bobcat’ tractor for the farmingpurpose. Bobcat tractor is a hydrostatic tractor that uses levers for steering, breaking and the forwardand backward movements. Two set of screw shaft driven by car power window motor were used tomove 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 willturn left when only the left lever is moved forward and vice versa. The friction between the levers andthe attachment was a major concern in this project. The bearing was introduced and the existencespace between the levers and the attachment can solve the friction problem. Autonomous tractorincreases the effectiveness of the field with little or no help of supervision
