An experimental platform has been built where software generated signals can be loaded into a transmission unit and echoes can be sampled and analyzed by the software. The current experiments utilizes electrostatic transducer elements. The multi-frequency measurement methods in sonar systems gives a much larger statistical material than those using a single frequency. Standing wave phenomena that may result in a zero amplitude at a certain frequency and distance do not deteriorate the measurement since the frequency is varied. Multi-frequency methods can be applied to pure distance measurements as well as to more complicated tasks. An experiment where the system is used for recognition is described.","PeriodicalId":136786,"journal":{"name":"Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130446122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we present an algorithm based on cellular automata for the path planning of a simple rigid body in a planar workspace with obstacles well known a priori. The environment model is realized with a regular decomposition in cells of predefined regular shape. The object has an orientation and has the limitation of moving forward on a smoothed trajectory without stopping and turning in place and with a minimum radius of curvature. We have implemented different versions of the algorithm, showing different properties of the model. The method is illustrated on examples with different characteristics to demonstrate the possibility of use on a real robot in a real environment.","PeriodicalId":136786,"journal":{"name":"Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123171212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The agent is not pre-programmed by its designer but was given simple rules of life, i.e. what is good and what is bad. By evaluating its sensor inputs these rules of life were transformed into a rule based reactive system. Simulations of the system showed that the agent is able to learn by its own experience. By representing the learned knowledge in an appropriate way, the acquired knowledge could be judged on its effectiveness and also this knowledge could be shared with other, less experienced agents.","PeriodicalId":136786,"journal":{"name":"Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96)","volume":"15 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132264213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem involves both perception and robotics, in that sensory-motion data are to be acquired and dynamically used for subsequent actions by the system. The basic processing concerns the extraction of the pipe contours which are returned as two straight lines. Motion effects on acquired images have been reduced using a Kalman filter for integrating multiple measurements over time. The filter, positioned at the output of the image processing system improves the precision in the computation of the straight line equations with a little overload. This work is originated from the interest of Snamprogetti in enhancing the level of automation in submarine pipeline inspection.","PeriodicalId":136786,"journal":{"name":"Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96)","volume":"45 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114303574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its construction, updating and usage is described, focusing on the techniques used for the integration of sensor data and on their fusion with a priori information about the environment. An additional mechanism that allows the map to be efficiently transmitted to a remote workstation, connected using a radio link, has also been envisaged. Thus the computational load of map related processes can be distributed, taking advantage of the remote station's computational power.

A major source of information are CCD-cameras which provide a detailed view of the robot's environment. This paper presents a real-time stereo algorithm implemented on the mobile robot RHINO of the University of Bonn. The algorithm exploit the phases of wavelet-filtered image pairs to localize edges and to estimate their disparities with subpixel accuracy. The disparities are computed by an initial search for corresponding points within a given interval and a subsequent measurement of phase-differences. The real-time constraints of autonomous object detection and navigation are fulfilled by partially implementing the stereo algorithm on a pipeline computer Datacube. Experimental results on real world scenes under real world conditions demonstrate the stereo algorithm's robustness and suitability for autonomous robot applications.","PeriodicalId":136786,"journal":{"name":"Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116298293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The algorithms examined are based on 2D laser scans and an odometry position estimate and do not need any modifications in the environment. An important requirement for the self-localization is the ability to cope with office-like environments as well as with environments without orthogonal and rectilinear walls. Furthermore, the approaches have to be robust enough to cope with slight modifications in the daily environment and should be fast enough to be used online on board of the robot system. To fulfil these requirements we made some extensions to the existing approaches and combined them in a suitable manner. Real world experiments with our robot within the everyday environment of our institute show that the position error can be kept small enough to perform navigation tasks.","PeriodicalId":136786,"journal":{"name":"Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128221835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It may still be worth retaining the idea that intelligent behaviour can be achieved through the accretion of modules each having a tight loop between perception and action but modules based on neural networks may have more potential. One approach that has been demonstrated is to train each module to achieve ifs individual competence. But although explicit teaching may play a part, a more interesting approach is to allow the agent to learn behaviours by interacting directly with the task environment. This paper presents a modular neural net architecture CRILL for the autonomous control of a mobile agent using a form of reinforcement learning. An experiment is described in which CRILL navigates through a simulated environment by seeking a series of light sources. The potential of the CRILL approach is assessed as a way of decomposing a complex goal and simplifying the construction of individual neural nets.","PeriodicalId":136786,"journal":{"name":"Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127560920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
