The paper presents a case-study of a developed robotic soil sample collection system from bottom to top. While the sampling process automation is solved by using the robotic platform and electro-hydraulic mechanism, the control system is connected with cloud-based software that enables to create and manage operation tasks. Any soil fertility management program includes collecting the soil samples. Properly managing the test points and conducting the sampling process have great effect on the results. To enable more frequent sample collection, achieve better efficiency and quality, there is a great need for soil sampling automation. In this paper the robotic platform developed in the Estonian University of Life Sciences is adapted and modified to collect and store soil samples from fields and measure the soil parameters simultaneously. The platform navigates and operates autonomously with dedicated software and remote server connection. The software purpose is to enable flexible functionality during autonomous soil sampling operation, view detailed telemetry and create work tasks. Using sensor fusion, the navigation software calculates the optimal driving trajectories and prevents collision with obstacles. Also, integration with the test area management system is discussed, which enables definition of the test area and assigning sample points.
