Title: Methodology for experimental research in multi-robot systems with case studies

Abstract: Fully repeatable and controllable experiments are essential to enable a precise comparison of multi-robot systems. Using different case studies, we describe a general methodology for conducting experimental activities for multi-robot systems. This is a first step toward the goal of fostering the practice of replicating experiments in order to compare different methods and assess their strengths and weaknesses.

In the first case study, we examine the problem of building a geometrical map of an indoor environment using multiple robots. The map is built by integrating partial maps made of segments without using any odometry information. We show how to improve the repeatability and controllability of the experimental results and how to compare different mapping systems.

We then present a case study of auction-based methods for the allocation of tasks to a group of robots. The robots operate in a 2D environment for which they each have a map. Tasks are locations in the map that must be visited by one robot. Robots bid to obtain tasks, but unexpected obstacles and other delays may prevent a robot from completing its allocated tasks. We show how to compare our experimental results with other published auction-based methods.

Title: Measuring Ground Robot Performance

Abstract: This talk first describes several approaches to measure the performance of ground robots. It is easy enough to measure quantities such as speed and reliability. It is more challenging to define metrics for perception, planning, and autonomy. The talk then presents selected results of applying the approaches to systems developed by several Goverment programs.

Title: Formalizing Educational Human-Robot Collaboration

Abstract: Designing human-robot collaboration systems is an inherently multidisciplinary endeavor aimed at providing humans with rich, effective and satisfying interactions. Over the past ten years, my laboratory has focused on educational collaboration, wherein the purpose of the interaction is to provide measurable learning for humans through exploration and discovery.

We propose that the creation of a successful human-robot collaboration system requires innovation in several areas: robot morphology; robot behavior; social perception; interaction design; human cognitive models and evaluation of educational effectiveness.

Our iterative process for collaboration design extends evaluation techniques from the informal learning field together with underlying technical advances in robotics. This talk describes our research methodology, technical contributions and experimental outcomes for three fielded robot systems that push on developing a generalizable, formal approach to educational human-robot collaboration.

For the past several months, our group has been laying the groundwork for large-scale dissemination of our technology and curricular instruments. I will describe the robot "community" we wish to help spawn, and the ingredients that may help to catalyze a broad form of technologically empowered community, including the Telepresence Robot Kit and the Global Connection Project.

Title: Building Autonomous Systems of High Performance, Reliability and Integrity

Abstract: Commercial applications for the everyday deployment of autonomous systems based on robotic and intelligent systems technologies require the highest levels of performance, reliability and integrity. The general public expects intelligent machines to be fully operational 100% of the time. People expect autonomous technologies to operate at higher levels of performance and safety than people themselves exhibit. For example smart car technologies are expected to cause ZERO accidents while human errors kill more 150,000 people on our roads every year! This talk will describe the design principles that have been developed over of the last 10 years through exhaustive trial and error testing to underpin autonomous systems that are suitable for real-world deployment. Currently, it is not yet possible to realise an autonomous system that doesn't fail periodically. Even if the mean rate between failures is days or weeks, a single failure could have catastrophic consequences. The approach we have adopted to address this situation has been to build-in monitoring systems that continually check all key system parameters and variables. If the monitored parameters move outside tightly defined bounds the system will safely shutdown, and alert the human supervisor. The failure conditions are logged and then further testing and debugging is performed. The value and appropriateness of our approach will be shown by a number of real-world studies. We will show that how it is possible to design computer vision systems for human-machine applications can operate with over 99% reliability, in all lighting conditions, for all types of users irrespective of age, race or visual appearance. These systems have been used in automotive and sports applications. We have also show how this approach has been used to design field robotic systems that have deployed in automobile safety systems and 24/7 mining applications.

Title: Human-Robot Interaction in Physical Proximity: Issues and Prospects

Abstract: After spectacular successes, in 1970s-1980s, in the use of robotics in highly structured environments - e.g. automotive assembly, welding, and painting lines - the penetration of "serious" robots (those large and powerful enough to be harmful) into new applications has slowed down markedly. User manuals of most robot arm manipulators warn that under no circumstance can people enter the workspace of an operating robot. The reason is simple - due to intended use these robots are strong enough to endanger a human, yet their sensing and intelligence is "too dumb" to be trusted for human safety. In the roboticists' parlance, today's robots are not designed to operate in unstructured environments, that is settings not created specifically for the robot's operation. It is not the function the robot is built for that is the problem - it is the robot's interaction with its environment. The problem is lesser with robot rovers but quite pronounced with arm manipulators.

The way to break this barrier is to design robots fully capable of operating in an unstructured environment, in places where things are unpredictable and must be perceived and decided upon on the fly. This is a new terrain - the required hardware and intelligence are to be more complex and sophisticated than what we know today. In this talk we will review related technical and scientific issues.
