Level Control for the Loading Bed of a Harvest Cart by the Pneumatic Servo System and Its Simulation Study

A series of works such as harvesting and transporting in a farm is one of such works with so care as not to damage the harvest in order to maintain the value of harvests. We are developing an autonomous cart for gathering a harvest with the bed to be controlled to keep in horizontally level, in order to avoid harvests gathered in particular area of the bed and avoid to be damaged in harvests. It is proposed a method of control of maintaining the horizontal level of the bed of the cart with air cylinder suspension systems.
