    Autonome Kartierungssysteme für landwirtschaftliche Anwendungen gewinnen zunehmend an Bedeutung. Derzeit sind die meisten Systeme ferngesteuert oder basieren auf einer einzigen globalen Umgebungsrepräsentation. Die alleinige Verwendung fester Roboterkarten und Aktionsschemata schränkt jedoch die Flexibilität autonomer Systeme ein. Insbesondere in der Landwirtschaft kann sich die Umgebung während der Vegetationsperioden schnell ändern, weshalb es einer kontextsensitiven Navigation bedarf. Ziel der hier vorgestellten Arbeit ist es, ein autonomes System namens Autonome robotische Experimentier-Plattform (AROX) aufzubauen, das in der Lage ist, Bestandskarten über einen gesamten Vegetationszeitraum ohne Benutzereingriff zu erstellen. Dazu haben wir die Hardware-Infrastruktur zum Aufbewahren und Laden des Roboters sowie die erforderliche Software im Robot Operating System (ROS) aufgebaut, um die Kontextsensitivität zu realisieren.

    Overview of a route-planning tool for capacitated field processes in arable farming
    (41. GIL-Jahrestagung, Informations- und Kommunikationstechnologie in kritischen Zeiten, 2021) Focke Martinez, Santiago; Wiemann, Thomas; Hertzberg, Joachim
    This paper presents an overview of a planning tool being developed for the generation of routes in the spatio-temporal domain for vehicles participating in capacitated arable farming operations. The planner supports processes where the field is divided into a surrounding headland and an inner-field (main) region. Two scenarios for output material flow operations are currently supported: 1) one machine equipped with a container works the field; and 2) a machine with no container works the field while being serviced on-the-run by one or more capacitated service units.

    prospective.HARVEST – Optimizing Planning of Agricultural Harvest Logistic Chains
    (40. GIL-Jahrestagung, Digitalisierung für Mensch, Umwelt und Tier, 2020) de Wall, Arne; Danowski-Buhren, Christian; Wytzisk-Arens, Andreas; Lingemann, Kai; Focke Martinez, Santiago
    The research and development project “prospective.HARVEST” aims at optimizing the process chain of silo maize harvesting, based on a predictive approach using prognosis data. New methods and tools have been developed utilizing remote and in-situ (geo-) data from a variety of data sources in order to enable farmers to optimize their logistic chains. Optimizations are computed as recommendations on several layers of the harvest process, from monitoring the crop over planning the inter-field and in-field coordination of harvesters and transport vehicles up to the surveillance and dynamic replanning of the ongoing harvest execution.

    Route-planning in output-material-flow arable farming operations aiming for soil protection
    (42. GIL-Jahrestagung, Künstliche Intelligenz in der Agrar- und Ernährungswirtschaft, 2022) Focke Martinez, Santiago; Hertzberg, Joachim
    This paper presents two approaches for route planning in output-material-flow arable farming: one for time optimization and one for soil protection. The two approaches were used to plan the routes of one harvester and one transport vehicle performing a harvesting operation in a test field, and were compared by analyzing the operation duration, travel distance, and area driven over by the machines. The results show the benefits and drawbacks of planning the machine routes using the proposed method for soil protection: the plans can reduce the impact of driving over the soil, but it can result in higher operation durations and traveled distances

    Route-planning in output-material-flow operations using side-headlands
    (43. GIL-Jahrestagung, Resiliente Agri-Food-Systeme, 2023) Focke Martinez, Santiago; Hertzberg, Joachim
    This paper presents an extension to a previously presented planning tool which was developed to generate routes for the machines participating in output-material-flow operations. The extension refers to the support of a headland region consisting of a set of partial side-headlands, comprised by main headlands, located in the sides of the field where inner-field tracks end; and connecting headlands, which border the field boundary and connect the main headlands. Eleven fields were used to test the corresponding tool updates in the planning process, including the geometric representation of the field with the new headland type, and the route planning for a harvesting test-scenario with one non-capacitated harvester and two transport vehicles.
