— In this work, we present a Hidden Markov Model (HMM) based workflow analysis of an assembly task jointly performed by a human and an assistive robotic system. In an experiment subjects had to assemble a tower by combining six cubes with several bolts for their own without the influence of a robot or any other technical device. To estimate the current(More)
— Knowledge about the static and dynamic situation is essential for joint workspaces of human and robot. Surveilling the joint area helps to realize a collaboration and coexistence of human and robot. Therefore, we propose in this paper a system that redundantly monitors the workspace to perceive obstacles within the workspace including the human worker. We(More)
— Within the ITrackU project, a modular software architecture for model-based visual tracking and image understanding is being developed. The library is general-purpose with respect to object models, state-space parameters, visual modalities employed, number of cameras and targets, and tracking methodology. This provides the necessary building blocks for a(More)
In this paper, a dynamic multi-modal fusion scheme for tracking multiple targets with Monte-Carlo filters is presented, with the goal of achieving ro-bustness by combining complimentary likelihoods based on color and foreground segmentation. The generality of the proposed approach allows defining the measurements on different levels (pixel-, feature-and(More)
In this paper, a distributed and scalable person tracking system for visual servoing using Industrial Robot Arms for virtual reality television studios (VR-TV) is presented. The system robustly tracks the moderator while freely moving, sitting or walking around the studio, and the estimation result can be used to drive the main broadcasting camera mounted(More)
At the moment, the collaboration of human and robot is mainly based on a master-slave level with a human tele-operating the robot or programming it off-line allowing the robot to execute only static tasks. In industrial production the limitations make a collaboration at the moment nearly impossible, because of the needed safety for the human worker.(More)
To study the network dynamics of the riboflavin biosynthesis pathway and to identify potential bottlenecks in the system, an ordinary differential equation-based model was constructed using available literature data for production strains. The results confirmed that the RibA protein is rate limiting in the pathway. Under the conditions investigated, we(More)
This article presents a modular, distributed and scalable many-camera system designed towards tracking multiple people simultaneously in a natural human-robot interaction scenario set in an apartment mock-up. The described system employs 40 high-resolution cameras networked to 15 computers, redundantly covering an area of approximately 100 square meters.(More)
After utilizing robots for more than 30 years for classic industrial automation applications, service robots form a constantly increasing market, although the big breakthrough is still awaited. Our approach to service robots was driven by the idea of supporting lab personnel in a biotechnology laboratory. After initial development in Germany, a mobile robot(More)
Both Robots and Personal Computers established new markets about 30 years ago and were enabling factors in Automation and Information Technology. However, while you can see Personal Computers in almost every home nowadays, the domain of Robots in general still is mostly restricted to industrial automation. Due to the physical impact of robots, a safe design(More)
