RoboCupRescue Interleague Challenge 2009: Bridging the gap between Simulation and Reality

The RoboCupRescue initiative, represented by real-robot and simulation league, is designed to foster the research and development of innovative technologies and assistive capabilities to help responders mitigate an emergency response situation. This competition model employed by the RobocupRescue community has proven to be a propitious model, not only for fostering the development of innovative technologies but in the development of test methods used to quantitatively evaluate the performance of these technologies. The Interleague Challenge has been initiated to evaluate real-world performance of algorithms developed in simulation, as well as to drive the development of a common interface to simplify the entry of newcomer teams to the robot league. This paper will discuss the development of emerging test methods used to evaluate robotic-mapping, the development of a common robotic platform, and the development of a novel map evaluation methodology deployed during the RoboCupRescue competition 2009

Quantitative Assessment of Robot-generated Maps

Mobile robotic mapping is now considered to be a sufficiently mature field with demonstrated successes in various domains. While much progress has been made in the development of computationally efficient and consistent mapping schemes, it is still murky, at best, on how these maps can be evaluated. We are motivated by the absence of an accepted standard for quantitatively measuring the performance of robotic mapping systems against user-defined requirements. It is our belief that the development of standardized methods for quantitatively evaluating existing robotic technologies will improve the utility of mobile robots in already established application areas, such as vacuum cleaning, robot surveillance, and bomb disposal. This approach will also enable the proliferation and acceptance of such technologies in emerging markets. This chapter summarizes our preliminary efforts by bringing together the research community towards addressing this important problem which has ramifications not only from researchers perspective but also from consumers, robot manufacturers, and developers viewpoints

Evaluation of Maps using Fixed Shapes : The Fiducial Map Metric

Mapping is an important task for mobile robots. Assessing the quality of those maps is an open topic. A new approach on map evaluation is presented here. It makes use of artificial objects placed in the environment named "Fiducials". Using the known ground-truth positions and the positions of the fiducials identified in the map, a number of quality attributes can be assigned to that map. Depending on the application domain those attributes are weighed to compute a final score. During the 2010 NIST Response Robot Evaluation Exercise at Disaster City an area was populated with fiducials and different mapping runs were performed. The maps generated there are assessed in this paper demonstrating the Fiducial approach. Finally this map scoring algorithm is compared to other approaches found in literature.Artificial Intelligence & Integrated Computer System

Road-Following Formation Control of Autonomous Ground Vehicles

This work presents a novel cooperative path planning for formation keeping robots traversing along a road with obstacles and possible narrow passages. A unique challenge in this problem is a requirement for spatial and temporal coordination between vehicles while ensuring collision and obstacle avoidance
