Abstract: The disclosure relates to a harvester (10) for harvesting logs. The harvester comprises a traction arrangement (11) configured to drive the harvester, an articulated boom (13) configured to connect to a processing head, a fuel reservoir, an electrical energy generator fuelled by a fuel from the fuel reservoir and configured for supplying power to the traction arrangement and the articulated boom, and an electrical connector (17) configured for coupling the electrical energy generator to an electrical energy storage of a shuttle. The harvester is configured to load a harvested log onto a coupled shuttle and charge the electrical energy storage of said coupled shuttle using electrical energy from the electrical energy generator.

Abstract: The disclosure relates to a forestry system (1). The forestry system comprises a harvester (10) comprising an electrical energy generator, and a plurality of self-driving shuttles (20a-f) for transporting logs harvested by the harvester. Each shuttle comprises an electrical energy storage and at least one electrical motor powered by the electrical energy storage. The electrical energy storage of said shuttle is configured to be coupled to the electrical energy generator and charged thereby. The harvester is configured to load a harvested log onto a coupled shuttle and charge the electrical energy storage of said coupled shuttle using electrical energy from the electrical energy generator.

Abstract: Disclosed herein is a forestry monitoring system comprising an unmanned aerial vehicle, UAV (30) and a computing device (35). The UAV comprises an electrical energy storage (31), an electric motor (32) powered by the electrical energy storage, a propulsion arrangement (33) driven by the electric motor and configured to aerially manoeuvre the UAV and an imaging arrangement (34) configured to collect information about a forestry site, the forestry site having one or more forestry machines performing forestry operations therein. The computing device is configured to obtain the collected information from the UAV, process the collected information to determine monitoring information for the forestry site, and determine a path decision for at least one of the one or more forestry machines based on the determined monitoring information of the forestry site.

Abstract: Described herein is a self-driving log forwarder shuttle system (1) comprising a self-driving log forwarder shuttle (20) a mobile charging station (10). The self-driving log forwarding shuttle (20) comprises an electrical energy storage (24), a log loading compartment (21) for receiving harvested logs, a traction arrangement (22) powered by the electrical energy storage (24) and configured to drive the shuttle (20), and a controller (26) connected to the traction arrangement (22) and configured to control the driving of the shuttle (20). The mobile charging station (10) comprises a fuel reservoir (12), an electrical energy generator (13) fuelled by a fuel from the fuel reservoir (12), and a traction arrangement (11) powered by the electrical energy generator (13) and configured to drive the mobile charging station (10). The shuttle (20) and mobile charging station (10) each comprise a respective electrical coupling (23) configured to mutually couple, thereby enabling charging of the electrical energy storage (24) of the shuttle (20) by the electrical energy generator (13) of the mobile charging station (10). Further described herein is a method for controlling such a system (1), the method comprising receiving logs in the log loading compartment (21) of the shuttle (20) and charging the electrical energy storage (24) of the shuttle (20) using the electrical energy generator (13) of the mobile charging station (10), wherein said receiving and said charging are at least partially simultaneous.
