Development of Program in VB to Compute Tractor Parameters on Automatic Steering

A comprehensible computer program is developed in Visual Basic studio to determine the tractor parameters for an automated steering system. Tractor parameters such as real wheel and front wheel trajectory coordinates, clockwise front and rear wheel angle and corrected front and rear wheel angle can be calculated. The input parameters of the developed program are mainly front wheel trajectory data, rear wheel trajectory, distance between front and rear wheel(X₁₃), Tractor velocity vector(V) and Tractor turning angle with center line. The tractor parameters are being calculated with the help of mathematical model which are already fed in program. The developed program successfully calculates the tractor parameters on automated steering system. This developed software could guide an autonomous agricultural tractor in the field. Furthermore, software navigates agricultural tractor both in straight or curved path at normal field operational speed.
