Simultaneous to industrial automation, automating agricultural tasks would be affordable for efficiency improvement. To obtain an applicable fully automatic vehicle in the straight rows and headland turning, an autonomous system was developed and evaluated in three different modes. The study was implemented on an actual sized, renewable energy based off-road vehicle called SAPHT (Solar Assist Plug-in Hybrid electric Tractor). Experimental evaluations were conducted based on machine vision and

... leoperation modes with various speeds. Vision system was developed based on random Hough transform and green plants were extracted from background using dynamic factors for each image. Statistical analysis of data in the straight plant rows illustrated the ability of vision-based guidance with maximum root mean square error of 5.7 cm without hurting any corn at the speed of 2 km/h. It's concluded that the applied vision based guidance system was suitable for inter-row operations while in headland turnings and also emergency commands, teleoperational control would be recommended.
