A Navigation Framework for Multiple Mobile Robots and its Application at the Expo.02 Exhibition
(2003)2003 IEEE International Conference on Robotics and AutomationThis paper presents a navigation framework which enables multiple mobile robots to attain individual goals, coordinate their actions and work safely and reliably in a highly dynamic environment. We give an overview of the framework architecture, its layering and the subsystems reactive obstacle avoidance, local path planning, global path planning, multi-robot planning and localization. The latter receives particular attention as the ...Conference Paper -
Multi-Robot Human-Interation and Visitor Flow Management
(2003)2003 IEEE International Conference on Robotics and AutomationIn this paper we address the task of human-robot interaction in public mass exposition with several autonomous robots at a time. This implies questions regarding multi-robot control and interaction management with respect to social and commercial aspects of such an exposition. Multi-robot and interaction management is addressed with respect to visitor density and visitor flow. Human-robot interaction is modeled using the SOUL environment. ...Conference Paper -
Narrative Situation Assessment for Human-Robot Interaction
(2003)2003 IEEE International Conference on Robotics and AutomationIn this paper we address the problem of interpreting sensory data for human-robot interaction, especially when gathered from several robots at the same time. After describing motion tracking in this context, we introduce a general framework for situation representation, and how it simplifies extraction of information suitable for complex machine dialogs. As a concrete implementation thereof, a narrative description of a complex scene in ...Conference Paper -
Smooth and Efficient Obstacle Avoidance for a Tour Guide Robot
(2003)2003 IEEE International Conference on Robotics and AutomationWe present the local path planning and obstacle avoidance method used on the autonomous tour-guide robot RoboX. It has proven its value during a 5 month operation of ten such robots in a real-world application, a very crowded exhibition. Three known approaches (DWA, elastic band, NF1) have been integrated into a system that performs smooth motion efficiently, in the sense of computational effort as well BS goal-directedness. Apart from ...Conference Paper -
3D-Odometry for rough terrain - Towards real 3D navigation
(2003)2003 IEEE International Conference on Robotics and AutomationUp to recently autonomous mobile robots were mostly designed to run within an indoor, yet partly structured and flat. environment. In rough terrain many problems arise and position tracking becomes more difficult. The robot has to deal with wheel slippage and large orientation changes. In this paper we willfirst present the recent developments on the offroad rover Shrimp. Then a new method, called 3D-Odometry, which extends the standard ...Conference Paper
