Carrying a large object like a table is a task that cannot be solved by a single robot or a single human, but that requires two workers, for example one human and one robot. For this human-robot cooperation, the robot must perceive the human and synchronize with its motion. It also must perceive the object to carry. In this paper, we present an approach that uses arm compliance to follow the human...
Joint attention between a human user and a robot is essential for effective human-robot interaction. In this work, we propose an approach to person awareness and to the perception of showing and pointing gestures for a domestic service robot. In contrast to previous work, we do not require the person to be at a predefined position, but instead actively approach and orient towards the communication...
Many perception problems in robotics such as object recognition, scene understanding, and mapping are tackled using scale-invariant interest points extracted from intensity images. Since interest points describe only local portions of objects and scenes, they offer robustness to clutter, occlusions, and intra-class variation. In this paper, we present an efficient approximate algorithm to extract...
Pointing gestures are a common and intuitive way to draw somebody's attention to a certain object. While humans can easily interpret robot gestures, the perception of human behavior using robot sensors is more difficult.
In this paper we present an approach to object segmentation and recognition that combines depth and color cues. We fuse information from color images with depth from a Time-of-Flight (ToF) camera to improve recognition performance under scale and viewpoint changes. Firstly, we use depth and local surface orientation extracted from the ToF image to normalize color and depth image features with regard...
Domestic service tasks require three main skills from autonomous robots: robust navigation in indoor environments, flexible object manipulation, and intuitive communication with the users. In this report, we present the communication skills of our anthropomorphic service and communication robots Dynamaid and Robotinho. Both robots are equipped with an intuitive multimodal communication system, including...
