In this perspective, it is not plausible for the meaning of the representations used by the robot to be given from outside the system itself. Rather, the meaning of internal symbols must be firmly anchored to the world through the perceptual abilities and the overall activities of the robot. According to these premises, we present an approach to action representation that is based on a \"conceptual\" level of representation, acting as an intermediate level between the symbols and data coming from the sensors. Symbolic representations are interpreted by mapping them onto the conceptual level through a mapping mechanism based on artificial neural networks. Examples of the proposed framework are reported, based on experiments performed on a RWI-B12 autonomous robot.","PeriodicalId":364500,"journal":{"name":"1999 Third European Workshop on Advanced Mobile Robots (Eurobot'99).

Building inverse sensor models for sonar sensor assemblies is a particularly difficult problem that has received much attention in the past few years. A common solution is to train neural networks using supervised learning. However, large amounts of training data are typically needed, consisting, for example, of scans of recorded sonar data which are labeled with manually constructed teacher maps. Obtaining these training data is an error-prone and time-consuming process. We suggest that it can be avoided if an additional sensor, like a laser scanner, is also available which can act as the feeding signal. We have successfully trained inverse sensor models for sonar interpretation using laser scan data. In this paper, we describe the procedure we used and the results we obtained.","PeriodicalId":364500,"journal":{"name":"1999 Third European Workshop on Advanced Mobile Robots (Eurobot'99).

Furthermore, there is an increasing demand that those systems perform not only a single task but show a whole set of different capabilities. This includes the concurrent and interruptable execution of several tasks. Reliably performing different tasks over long periods of time not only requires advanced basic skills, but also an appropriate robot control architecture. This includes, e.g., mechanisms to coordinate the execution of competing tasks. We present the architecture used on our B21 demonstrator of the SFB 527. A special emphasis is laid on aspects of our supporting software framework, SMARTSOFT, and the implemented set of skills.","PeriodicalId":364500,"journal":{"name":"1999 Third European Workshop on Advanced Mobile Robots (Eurobot'99).

Using the condensation algorithm to implement tracking for mobile robots 利用凝聚算法实现移动机器人的跟踪

Tracking can increase the robustness, especially when occlusions occur or when objects temporally disappear. The standard approach for tracking is to use a Kalman filter for every object. This, however requires the use of a high complexity management system to deal with the multiple hypotheses necessary to track all anticipated objects. We present a stochastic approach which is based on the CONDENSATION algorithm-conditional density propagation over time-that is capable of tracking multiple objects with multiple hypotheses in range images. A probability density function describing the likely state of the objects is propagated over time using a dynamic model. The measurements influence the probability function and allow the incorporation of new objects into the tracking scheme. Additionally, the representation of the density function with a fixed number of samples ensures a constant running time per iteration step. Results on different data sources are shown for mobile robot applications.","PeriodicalId":364500,"journal":{"name":"1999 Third European Workshop on Advanced Mobile Robots (Eurobot'99).

Numerous technical problems had to be solved during this period. Currently, we are operating and testing it in our office building. A service robot like MOPS is a highly complex system, as it includes, in addition to the robot itself, the task, the operator, and the environment. Operating experiences with such service robots are not easily available yet. They would be of value, as in the end customer acceptance will decide upon the actual use of service robots. Technical aspects of the realization of MOPS are discussed briefly.

The concept of geometrical database is associated with multiple classes of perception-based maps, to obtain the world model. Task-oriented maps are produced by grouped sensors. Two different representations of the environment are considered, namely vector-based and raster-based maps. Sensed maps are checked for consistency with the predefined model. The multi-agent approach has been applied with respect to the system architecture. As a consequence, world-model maintenance activity consists of a number of processes, which are driven by the team of agents.
