1.3 Research profile

My research follows two main tracks: Field Robotics and Cognitive Robotics. In the areaof Field Robotics, we have done and still do a lot of research for automation in forestry1,in particular development of unmanned forest vehicles. Our major contributions in thisresearch project is a pilot system for autonomous navigation in forest environment [25, 63],including algorithms for high-performance path tracking in rough forest environment [17],and simulator based path planning for both obstacle avoidance and global reactive pathplanning [22]. We also analyze visionary views and requirements for forestry automation[23, 27, 103], and develop methods for simulation of the potential of different machinesystems in forestry, including autonomous vehicles [15]. The field robotics track wascontinued within the EU project CROPS (IP FP7/NMP). The overall goal of CROPSwas to develop robots for harvesting and spraying of fruit and vegetable crops. Ourmajor contributions were to develop a generic robot system architecture [51, 13, 55].We also worked on laser and image analysis solutions for estimation of tree diameters[12], detection and classification of objects in forest environments [50, 54], and generaltechniques for image labelling and segmentation. The work in CROPS is continued in theSWEEPER (H2020) project.

Our second main track of research, Cognitive Robotics, has for several years beenconducted in the EU project INTRO (FP7/ITN) for which I was coordinator (2010-2014).In our lab, work has focused on cognitive architectures and robot learning, primarilyLearning From Demonstration (LFD) enhanced by HRI [8, 9, 46, 7, 61]. We also work withnatural language understanding for robotics [48, 45, 44], and currently combine semanticparsing with cognitive architectures, robot control architectures and task planning. Thiswork is conducted as part of the SOCRATES (H2020) project for which I am coordinator.

In addition to the main tracks, Field Robotics and Cognitive Robotics, I have publishedsome work on robot ethics related to development and usage of military robots [14, 86].I also lead a project2 for development of an intelligent rollator, aiming at improvingusability for people with cognitive limitations, e.g. after a stroke [88, 2].

In my earlier research, leading up to my Ph.D. degree in 2001, I worked with finan-cial modeling, predictions and machine learning in general. A complete description ofmy research profile has to include my commercial work with nautical control systems.For several years I worked as self-employed with development of the Seapacer system3,with advanced functions for propeller pitch optimization, route planning and dynamicspeed and fuel consumption control. Besides the commercial endeavor, I published a fewscientific papers on the project [29, 28, 77, 104].

2.6 Patent applications

In 2010, I invented the Intelligent Rollator, an enhanced rollator for handicapped andold people. The rollator uses sensors and other robot technology to detect and avoidseveral types of obstacles. The reduced risk for collisions increases users’ confidence inthe rollator, such that it is used more often compared to traditional rollators. In July2012, the innovation was granted Swedish patent number SE535373 C2.
