A real-time SLAM (simultaneous localization and mapping) approach to harvester localization and tree map generation in forest environments is presented in this paper. The method combines 2D laser localization and mapping with GPS information to form global tree maps. Building an incremental map while also using it for localization is the only way a mobile(More)
For the last decades, measurement and automation systems in Nordic cut-to-length forestry machines have evolved gradually. These heavy duty machines are lighter, faster and more accurate than ever before but the basic technologies and operation have remained the same. In many respects, their current automation systems have reached their limits. The(More)
Fault diagnostics in industrial applications has become very popular research topic. In agriculture the time window to complete tasks may be very short. Timing the field operations is critical when machine and human resources are limited. Different kind of dynamic model based fault detection and diagnosis methods have been studied throughout the process(More)
