Abstract

Free-flight concept is a modern approach to flexible collision free air traffic control investigated mainly in the context of unmanned aerial assets. Agent Technology Center (ATG) at the Czech Technical University designed and developed AGENTFLY, a multi-agent simulation environment used for a variety of coordinated UAA scenarios. Several collision avoidance methods (e.g. based on visual flight rules, based on peer-to-peer negotiation, based on multi-party interaction or prediction) and a specific A* based planning algorithm were successfully tested and demonstrated in AGENTFLY system. During my talk I will share with the audience experience collected during the AGENTFLY system development, will present several demos and will comment on industrial take up of the system.

Abstract

The ARCAA has been conducting research in the area of robotic aircraft (UAS, UAV, ..) since 1999. In this time the group has been on journey of understanding, beginning with very little knowledge of the problems associated with these vehicle, and looking from the elec eng/computer science perspective.  This talk will address the issues of societal acceptance of UAS, followed by a discussion of current issues associated with regulatory impediments. Specific comment will be made in the Australian context. It will also highlight problems that remain to be solved for UAS.

Research results will be provided for two research thrusts; namely the emergency (or forced) landing problem and the "see and avoid" problem.  These areas being investigated for automation through the use of computer vision techniques. A brief overview and video of our flight test activities for the "Smart Skies" program (an automated aircraft separation program) and our robotic powerline asset inspection program will be provided. Finally, speculation of the future development path, and likely hurdles, for robotic aircraft will be provided.

Title:         MOVIII Distinguished Lecture, Thursday May 28th 9.00-10.00 Wolfram Burgard

                Probabilistic Techniques for Mobile Robot Navigation

Speaker:   Wolfram Burgard, Albert-Ludwigs-Universität Freiburg, Germany

Date:        2009-05-28

Time:        09.00-10.00

Place:       Visionen, entrance B27, B-Building, Campus Valla, LiTH

Language: English

 

Abstract

In recent years, probabilistic techniques have enabled novel and innovative solutions to some of the most important problems in mobile robotics.  Major challenges in the context of probabilistic algorithms for mobile robot navigation lie in the questions of how to deal with highly complex state estimation problems and how to control the robot so that it efficiently carries out its task.  In this talk I will discuss both aspects and present an efficient probabilistic approach to solve the simultaneous mapping and localization problem for mobile robots.  I will also describe how this approach can be combined with an exploration strategy that simultaneously takes into account the uncertainty in the pose of the robot and in the map. For all algorithms I will present experimental results, which have been obtained with mobile robots in real-world environments as well as in simulation. I will conclude the presentation with a discussion of open issues and potential directions for future research.

Title:         MOVIII Seminar - Cognition, Control and Learning for Everyday Manipulation Tasks in Human Environments

Speaker:   Michael Beetz, Technische Universität München, Germany

Date:        2009-03-19
Time:        15.15-16.00

Place:       Visionen, entrance B27, B-Building, Campus Valla, LiTH

Language: English

 

Abstract

In recent years we have seen tremendous advances in the mechatronic, sensing and computational infrastructure of robots, enabling them to act faster, stronger and more accurately than humans do. Yet, when it comes to accomplishing manipulation tasks in everyday settings, robots often do not even reach the sophistication and performance of young children.  This is partly due to humans having developed their brains into computational and control devices that facilitate knowledge-informed decision making, perspective taking, envisioning activities and their consequences, and predictive control. Brains orchestrate these learning and reasoning mechanisms in order to produce flexible, adaptive, and reliable behavior in real-time. Household chores are an activity domain where the superiority of the cognitive mechanisms in the brain and their role in competent activity control is particularly evident.

In this talk, I will give an overview of the Intelligent Autonomous Systems group's ongoing research in the excellence cluster "Cognition for Technical Systems", in which we investigate --- in an interdisciplinary endeavor --- cognitive mechanisms that are to enable autonomous robots to produce flexible, reliable and high-performance behavior for everyday manipulation activities. The talk will step through the "cognitive perception-action loop" for robot control focusing on the acquisition and use of environment models for housework as a running example.

Title:         PhD Defense : DyKnow: A Stream-Based Knowledge Processing Middleware Framework

Abstract
As robotic systems become more and more advanced the need to integrate existing deliberative functionalities such as chronicle recognition, motion planning, task planning, and execution monitoring increases. To integrate such functionalities into a coherent system it is necessary to reconcile the different formalisms used by the functionalities to represent information and knowledge about the world. To construct and integrate these representations and maintain a correlation between them and the environment it is necessary to extract information and knowledge from data collected by sensors. However, deliberative functionalities tend to assume symbolic and crisp knowledge about the current state of the world while the information extracted from sensors often is noisy and incomplete quantitative data on a much lower level of abstraction. There is a wide gap between the information about the world normally acquired through sensing and the information that is assumed to be available for reasoning about the world.

As physical autonomous systems grow in scope and complexity, bridging the gap in an ad-hoc manner becomes impractical and inefficient. Instead a principled and systematic approach to closing the sensereasoning gap is needed. At the same time, a systematic solution has to be sufficiently flexible to accommodate a wide range of components with highly varying demands. We therefore introduce the concept of knowledge processing middleware for a principled and systematic software framework for bridging the gap between sensing and reasoning in a physical agent. A set of requirements that all such middleware should satisfy is also described.

A stream-based knowledge processing middleware framework called DyKnow is then presented. Due to the need for incremental refinement of information at different levels of abstraction, computations and processes within the stream-based knowledge processing framework are modeled as active and sustained knowledge processes working on and producing streams. DyKnow supports the generation of partial and context dependent stream-based representations of past, current, and potential future states at many levels of abstraction in a timely manner.

To show the versatility and utility of DyKnow two symbolic reasoning engines are integrated into Dy-Know. The first reasoning engine is a metric temporal logical progression engine. Its integration is made possible by extending DyKnow with a state generation mechanism to generate state sequences over which temporal logical formulas can be progressed. The second reasoning engine is a chronicle recognition engine for recognizing complex events such as traffic situations. The integration is facilitated by extending DyKnow with support for anchoring symbolic object identifiers to sensor data in order to collect information about physical objects using the available sensors. By integrating these reasoning engines into DyKnow, they can be used by any knowledge processing application. Each integration therefore extends the capability of DyKnow and increases its applicability.

To show that DyKnow also has a potential for multi-agent knowledge processing, an extension is presented which allows agents to federate parts of their local DyKnow instances to share information and knowledge.

Finally, it is shown how DyKnow provides support for the functionalities on the different levels in the JDL Data Fusion Model, which is the de facto standard functional model for fusion applications. The focus is not on individual fusion techniques, but rather on an infrastructure that permits the use of many different fusion techniques in a unified framework.

The main conclusion of this thesis is that the DyKnow knowledge processing middleware framework provides appropriate support for bridging the sense-reasoning gap in a physical agent. This conclusion is drawn from the fact that DyKnow has successfully been used to integrate different reasoning engines into complex unmanned aerial vehicle (UAV) applications and that it satisfies all the stated requirements for knowledge processing middleware to a significant degree.



Title:         MOVIII Seminar - Optimal placement of communications relay nodes

Speaker:   Oleg Burdakov, Div. of Optimization, MAI, LiTH

Date:        2009-03-12

Abstract

We consider a constrained optimization problem with mixed integer and real variables. It models optimal placement of communications relay nodes. This problem is widely encountered, for instance, in robotics,
where it is required to survey some target located in one point and convey the gathered information back to a base station located in another point. One or more unmanned aerial or ground vehicles (UAVs or
UGVs) can be used for this purpose as communications relays. The number of unmanned vehicles (UVs) is the only integer among the decision variables. The positions of UVs specified by real variables are
assessed by a merit function, and the sum of the function values is to be minimized. We suggest to use an obstructed volume as a merit function, whose value is determined by the UV position and the local
terrain around it. The relay of UVs are required to be placed in the area of interest subject to the following requirements. Firstly, the line segment connecting any consecutive pair of UVs, the base and the
first UV, as well as the last UV and the target, should not intersect with the obstacles (a free line of sight requirement). Secondly, the distance between these pairs should not exceed a given limit defined by
the communication range. Because of these requirements, our constrained optimization problem is a difficult multi-extremal problem for any fixed number of UVs. Moreover, the feasible set of real variables is
typically disjoint. We present an approach that allows us to efficiently find a reasonably accurate approximation to a global minimum in the problem of optimal placement of communications relay
nodes. It is based on a spatial discretization with a subsequent reduction to the shortest path problem.

 

The case of a restricted number of available UVs is also considered here. We introduce two label correcting algorithms which are able to take advantage of using some peculiarities of the resulting restricted
shortest path problem. The algorithms produce a Pareto solution to the two-objective problem of minimizing the path cost and the number of hops. We prove the correctness of these algorithms. The presented
results of numerical 3D experiments show that our algorithms are superior to the conventional Bellman-Ford algorithm tailored to solving this problem.

Abstract
The trend today is to use many inexpensive sensors instead of a few expensive ones, since the same accuracy can generally be obtained by fusing several dependent measurements. It also follows that the robustness against failing sensors is improved. As a result, the need for high-dimensional regression techniques is increasing.
 
As measurements are dependent, the regressors will be constrained to some manifold. There is then a representation of the regressors, of the same dimension as the manifold, containing all predictive information. Since the manifold is commonly unknown, this representation has to be estimated using data. For this, manifold learning can be utilized. Having found a representation of the manifold constrained regressors, this low-dimensional representation can be used in an ordinary regression algorithm to find a prediction of the output. This has further been developed in the Weight Determination by Manifold Regularization (WDMR) approach.
 
In most regression problems, prior information can improve prediction results. This is also true for high-dimensional regression problems. Research to include physical prior knowledge in high-dimensional regression i.e., gray-box high-dimensional regression, has been rather limited, however. We explore the possibilities to include prior knowledge in high-dimensional manifold constrained regression by the means of regularization. The result will be called gray-box WDMR. In gray-box WDMR we have the possibility to restrict ourselves to predictions which are physically plausible. This is done by incorporating dynamical models for how the regressors evolve on the manifold.

Title:         Licentiate Seminar: Look-ahead Control of Heavy Trucks utilizing Road Topography

Speaker:   Erik Hellström
Date:        2007-06-13
Time:        10:15
Place:       Visionen, B-huset, ing 27, Campus Valla, LiTH
Language: English

 

Abstract
The power to mass ratio of a heavy truck causes even moderate slopes to have a significant influence on the motion. The velocity will inevitable vary within an interval that is primarily determined by the ratio and the road topography. If further variations are actuated by a controller, there is a potential to lower the fuel consumption by taking the upcoming topography into account. This possibility is explored through theoretical and simulation studies as well as experiments in this work.

Look-ahead control is a predictive strategy that repeatedly solves an optimization problem online by means of a tailored dynamic programming algorithm. The scenario in this work is a drive mission for a heavy diesel truck where the route is known. It is assumed that there is road data on-board and that the current heading is known. A look-ahead controller is then developed to minimize fuel consumption and trip time.

The look-ahead control is realized and evaluated in a demonstrator vehicle and further studied in simulations. In the prototype demonstration, information about the road slope ahead is extracted from an on-board database in combination with a GPS unit. The algorithm calculates the optimal velocity trajectory online and feeds the conventional cruise controller with new set points. The results from the experiments and simulations confirm that look-ahead control reduces the fuel consumption without increasing the travel time. Also, the number of gear shifts is reduced. Drivers and passengers that have participated in tests and demonstrations have perceived the vehicle behavior as comfortable and natural.

Abstract
Imaging of Brain Activity using fMRI is one of three demonstrator projects in MOVIII. The main goal of the project is to close the loop and create a stimulus based on the measured fMRI response. This opens up a whole new dimension in the field. The brain could for example be steered into the predefined state of maximum relaxation or concentration. There are many possibilities and questions. We hope to given an introduction to the field and to share some of our questions and enthusiasm.

 

The talk will be divided into four parts.

 

Hans Knutsson, IMT:

An introduction to the field of magnetic resonance imaging will be given. The focus will be on how magnetic gradients are used to produce images, and on the relaxation processes which generate the fMRI signal.

 

Joakim Rydell, IMT:

Analysis methods of fMRI data will be exemplified. How is data from the MR scanner analyzed to detect active regions in the brain? Two methods for adaptive filtering and analysis will be presented.

 

Anders Brun, IMT:

Non-linear dimensionality reduction or manifold learning is a hot topic which is highly relevant for the project. We will discuss the impact and use of these methods for signal and image processing tasks relevant to the MOVIII community.

 

Henrik Ohlsson, ISY:

Last, an update of the current status of the demonstrator. Interesting questions will be brought up, a look in the future and hopefully some discussion.

Title:            MOVIII Seminar - Navigating UAV’s

Abstract
The MOVIII UAV demonstrator should as a first milestone be able to autonomously find its way back to homebase without relying on GPS. To prevent drift from dead-reckoning inertial sensor information, visual support is needed. This presentation overviews recent research to reach this goal:

1)       Visual odometry by correlating video frames to satellite images,

2)       The Harris feature detector to locate natural landmarks, and new results on its statistical properties (bias and variance).

3)       The new algorithm on fast MPF SLAM (simultaneous localization and mapping).  Fast SLAM is a recent algorithm developed by the robot community. The adaptive map here consists of detected landmarks using the Harris detector, and tracking these stabilizes drift. MPF refers to that dynamical models of large state dimension can be used in the navigation filter.

The fast MPF SLAM algorithm will be the heart of the sensor fusion algorithm, where visual odometry and Harris features are used as inputs. The subjects in the talk will be illustrated on data from recent field trials.

Title:         DyKnow - A Knowledge Processing Middleware
Speaker:   Patrick Doherty and Fredrik Heintz, LiTH, IDA
Date:        2007-03-01
Time:        13:15-14:00
Place:       Glashuset, entrance B25, B-Building, Campus Valla, LiTH
Language: English

Abstract
Any autonomous system embedded in a dynamic and changing environment must be able to create qualitative knowledge and object structures representing aspects of its environment on the fly from raw or preprocessed sensor data in order to reason qualitatively about the environment and to supply such state information to other nodes in the distributed network in which it is embedded. These structures must be managed and made accessible to deliberative and reactive functionalities whose successful operation is dependent on being situationally aware of the changes in both the robotic agent's embedding and internal environments. DyKnow is a knowledge processing middleware framework which provides a set of functionalities for contextually creating, storing, accessing and processing such structures. This talk will give a concrete introduction to DyKnow and its functionalities.

Abstract
Simultaneous Localization and Mapping (SLAM) is the process where a map is built from measurement data at the same time as the vehicle location is determined. The almost finished MATRIS project focuses on the localization part and assumes that the map is known. Some recent results will be presented as well as our attempts to extend this to complete SLAM.
