A tilling robot capable of unmanned rotary tilling with the XNAV navigation system was examined to improve and expand the adaptability of the robot operation. Firstly, as an effective and safe method of using the robot, we proposed a method whereby one operator manually operated a conventional tractor while engaged in the unmanned operation of a robot tractor. As a result of the rotary tilling test, to which the use method was applied, the robot operation was performed without trouble, and one operator could perform the operation with efficiency about 1.8 times superior to manned operation. Secondly, as an application to farm work other than rotary tilling, operation software for seeding and soil paddling was created based on operation software for rotary tilling. From the results of robot wheat seeding field tests, it was proved that the operation could be successfully performed without trouble and that the conventional two-person work could be done by one operator. The robot soil paddling was also successfully performed with efficient operation paths compared to manned operation.
