Prof. Henrik Christensen
Title: Evaluation of Robots for Human-Robot Interaction
Abstract: Robotics is gradually maturing as a discipline which also implies an increased need for comparative R&D. At the same time robots are more and more deployed to serve as assistants to humans be it for search and rescue or as part of normal daily chores in the home. To enable evaluation of progress in research it is essential that rigorous methodologies for evaluation and performance characterisation are adopted. Often a number of objections are put forward as to why such rigorous experimental protocols are not well suited for robotics. Some of the typical objections will be presented and discussed in the presentation. To illustrate the value and strategy of experimental evaluation two example applications will be presented. Both applications are closely tied to robots that serve as assistants to people as part of daily operations.
A Wizard-of-Oz study has been used for the design of a strategy for joint human-robot mapping of domestic setting as part of creation of a cognitive robots for assistance to people in their homes. The Wizard-of-Oz study clearly illustrate some of the challenges that a robot has to cope with and indicate a number of important issues to be considered in the design of dialog behaviours and associated autonomous functionality. We will here discuss the use of initial exploratory system designs to ensure early integration of the end-user.
Another study has considered the deployment of iRobot PackBot systems for assistance to soldiers as part of urban intervention. Integration of robots into a unit of soldiers poses a number of interesting challenges. There is a here a need to consider the impact of the system on the robot operator and to re-consider the entire strategy for urban intervention when a unit is equipped with a light-weight robot for scouting. Results from a study with the international brigade from the Swedish military are presented and a number of important lessons from a long-term (12 month) study is reported.
Experience from prior studies clearly illustrate the value of a careful design for evaluation and characterisation of systems, which goes beyond the simple verification of theoretical models. Observations and lessons from an extensive set of studies are summarized.
Biography: Henrik I Christensen is the Kuka Chair of Robotics and a Professor of Computing with the College of Computing, Georgia Institute of Technology. The appointment is part-time during 2006, which is a transition period from the earlier appointment at the Swedish Royal Institutute of Technology , which included leadership of the Center for Autonomous Systems. He does research on mobile robotics, autonomous systems, computer vision, and biologically inspired robot systems. The overall emphasis is on a holistic approach to design of systems, incl mathematically well defined methods for design, analysis and implementation of systems. A fundamental idea is that methods should be evaluated in realistic settings which involves an interesting scenario and a full systems context. He is involved in a large number of national and international projects. Dr. Christensen is a co-founder of the company Intelligent Machines and serve as a scientific advisor to Evolution Robotics. Research cooperation involves research labs and companies on three continents. In addition he has been actively involved in a number of community efforts in particular as the founding coordinator of the EU network of excellence in Robotics - EURON (2000-2006). Dr. Christensen is a fellow of the International Foundation of Robotics Research and served as an IEEE RAS distinguished lecturer (2004-2006). He also serves on the board of trustees of the Swedish STINT foundation.

Title: Development of Rescue and Demining Robots in Tokyo Institute of Technology
Abstract: In this plenary talk, I will explain about our activities on rescue and demining robots. As for the robots for rescue operation, I will first explain my previous efforts on snake-like robots with slender and actively bending bodies. I will then show several types of snake-like "Soryu" robots which consist of three crawler-driven segments and their connecting joints. The Soryu has been adapted with a specific driving mechanisms to move inside narrow and winding paths among debris and is designed to protect against dust and water. A newly introduced crawler belt made of thin metal with rubber knobs will also be explained. I will also present a debris-inserting inspection camera, we are developing with a snake-like expandable rod mechanism. In general, I will introduce our development process for these and other devices. We believe that the most effective rescue tools will be the ones which are widely used in our daily life. Based on this belief, we also paid special attention to the development of ordinary-life-embedded rescue devices. For example, automobile jack-up devices which can be used for rescue operations will be shown. As for the demining robots, I will explain about my preliminary efforts to develop walking-demining robots, and their tool-detachable foot mechanisms. I will explain about our latest activities on a practical demining vehicle named "Gryphon." It has a weight balanced arm with metal and ground penetrating radar and a 3D camera. It can measure the uneven ground and can drive the sensors along the surface of the ground. I will show the result of the experiments in several places such as in Croatia.

Prof. Hugh Durrant-Whyte
Title: Maximal Information Systems
Abstract: Information provides a quantitative metric for describing the value of individual systems components in autonomous systems tasks such as tracking, mapping and navigation, search and exploration; tasks in which the objective is information gain in some form. An information model is an abstraction of system capabilities in an anonymous form which allows a priori reasoning on the system itself. By construction, information measures have properties of composability and additivity and thus provides a natural means of modelling and describing large scale systems of systems.
This talk will begin by describing how information measures arise naturally in autonomous tracking, mapping and navigation, search and exploration tasks. It is then demonstrated that the performance of individual sensors and platforms can be modelled using these information measures and that system-level performance metrics can be computed. These ideas are illustrated in a series of tasks involving mixed air and ground autonomous systems. These include flight-tests of cooperative UAVs engaged in tracking and navigation tasks, mixed UAV, ground vehicles and human operatives, engaged in mapping and picture compilation operations, and operations involving multi-platform search in constrained environments. In each, it is shown how information provides both a performance metric and design objective underpinning large-scale systems of systems operation.

Dr. Martin Buehler
Title: Developing Dynamic Legged Robots - Towards Greater Mobility Without Falling Over
Abstract: Mobility can be an important contributor to robot intelligence, for gathering information, implementing decisions, and interacting with the environment. While wheeled and tracked robots have a relatively easy time moving around, we have to invest some intelligence first into legged robot design and control in order to harvest their potentially much greater mobility.
This talk will describe several recent legged robots that walk, run, balance, climb, carry loads, resist kicks and negotiate rough terrain with new levels of dynamic mobility, robustness, and performance. In the process we will encounter interesting issues related to the system design, performance metrics, energy efficiency, and the experimental evaluation of these systems.
Biography: Martin Buehler received the M.Eng. and Ph.D. degrees in Electrical Engineering from Yale University in 1985 and 1990. His doctoral work focused on the design, control and analysis of juggling robots and the analysis of a hopping robot. After a Postdoc at MIT's leglab on dynamic legged locomotion, he joined McGill University, Montreal, in 1991 as an NSERC Junior Industrial Research Chair and a Scholar of the Canadian Institute for Advanced Research. He founded and headed the Ambulatory Robotics Lab, which produced one, four and six legged robots, including the ARL Monopods I and II, Scout I and II, CARL, PAW, RHex and AQUA, funded by major Canadian government, DARPA and industrial contracts and grants. In 2003 he received McGill's William Dawson Scholar Award. In the same year he moved on to become Director of Robotics at Boston Dynamics, Cambridge, USA.

Dr. James Albus
Title: Building Brains for Thinking Machines
Abstract: In this talk, Dr. Albus will describe how research in computer science, control theory, and the neurosciences are converging towards intelligent systems that can mimic human performance in a broad range of applications. He will discuss current efforts to build machines that can perceive the environment, build an internal model of the external world, and use that model for decision-making, reasoning, planning, and real-time control of complex machines in uncertain, and potentially hostile, environments. He will suggest how system architectures designed for autonomous mobility systems are computationally similar in many respects to the human brain, and vice versa.
This work is part of a broad NIST program of research and engineering of intelligent systems to reduce costs and improve quality in manufacturing and construction, and to save lives of civilians on the highway and soldiers in combat. The research is conducted in collaboration with the Army Research Laboratory, DARPA, the Department of Transportation, and the U.S. manufacturing industry.
