In this paper we present large, accurately calibrated and time-synchronized data sets, gathered outdoors in controlled and variable environmental conditions, using an unmanned ground vehicle (UGV), equipped with a wide variety of sensors. These include four 2D laser scanners, a radar scanner, a color camera and an infrared camera. It provides a full description of the system used for data collection and the types of environments and conditions in which these data sets have been gathered, which include the presence of airborne dust, smoke and rain.

This paper describes how to use signs as a part of the work task scenarios with service robots. The signs are introduced as an alternative or complementary tool for passing information of the task plan of a work task from the human operator to the service robot. The signs can be used for pointing a direction, bounding an area, marking a route, or defining location of a target. There are two kinds of signs, passive and active. The passive signs have all the information in their appearance. In active signs the information content can be modified, for example with radio communication. Moreover, active signs can be equipped with sensors such as GPS-receiver and compass to measure their location on the map. One of the advantages of using signs to control work tasks is usability. The signs are just carried to the working area and no other actions are needed. Tests in real outdoor and non-structured environments with the WorkPartner robot are realized and experimental results are shown.
