The EAS100 is an eSurvey new generation electric wheel-based auto-steering system. The eSurvey EAS100 helps to transfer farm work from fully manual driving to semi-automatic operation. It means high time efficiency and less operator fatigue. Based on the route planning algorithm, the vehicle could go through the same paths every time to seed, spray and harvest with ±2.5 cm accuracy, which increases crop yield and reduces chemical usage.
