Intelligent rescue systems with high information and robot technology have been expected to mitigate disaster damages, especially in Japan after the 1995 Hanshin-Awaji earthquake. In development of robots for search and rescue tasks it is important to develop a robot which can actually work in a real disaster site. Several robots were used for the search and detection operation in the collapsed World Trade Center building in September 2001. From 2002 "Special Project for Earthquake Disaster Mitigation in Urban Areas" (5 years project) launched by Ministry of Education, Culture, Spots, Science and Technology, Japan. It aims at significant mitigation the earthquake disaster damage on the scale of the Great Hanshin earthquake, in densely populated areas in big city regions such as Tokyo metropolitan area and Keihanshin area. In this paper, we introduce the activities of the mission unit on the information collection by on-rubble mobile platforms

Personal robots, which are expected to become popular in the future, are required to be active in joint work and community life with humans. Such robots must have no bad physical or psychical effect on humans. The psychical effect of a robot on humans has been subjectively measured using questionnaires. However, it has not been objectively measured yet. Human emotion and the consciousness direction can be measured by physiological parameters and body motion, respectively. Therefore, the bioinstrumentation system WB-1 was developed in order to objectively measure the psychical effect of a robot on a human. It can measure physiological parameters such as respiration, heart rate, perspiration and pulse wave, and arm motion. Analyzing human stress in the interaction with a robot from electrocardiogram, the robot could generate a motion for decreasing the stress

The capability of autonomous and semiautonomous platforms to fraction in the shallow water surf zone is critical for a wide range of military and civilian operations. Of particular importance is die ability to transition between locomotion modes in aquatic and terrestrial settings. The study of animal locomotion mechanisms can provide specific inspiration to address these demands. In this work, we summarize on-going efferts to create an autonomous, highly mobile amphibious robot A water-resistant amphibious prototype design, based on the biologically-inspired Whegs™ platform, has been completed. Through, extensive field-testing, mechanisms have been Isolated to improve the implementation of die Whegs™ concept and make it more suited for amphibious operation. Specific design improvements include wheel-leg propellers enabling swimming locomotion, an active, compliant, water resistant, non-backdrtvable body joint, and improved feet for advanced mobility. These design innovations will allow Whegs™ IV to navigate on rough terrain and underwater, and accomplish tasks with little or no low-level control, thus greatly simplifying autonomous control system implementation. Complementary work is presently underway for autonomous control. We believe these results will lay the foundation for the development of a generation of amphibious robots with an unprecedented versatility and mobility. © 2005 IEEE.

Analysis of Optimal Sets of Survivable Paths in Undirected Simple Graph Applicable for Optical Networks

Electronic Notes in Discrete Mathematics 2005年 22卷 1-5页

作者： Bogdanowicz, Z.R. Intelligent Systems and Robotics Laboratory Armament Research Development and Engineering Center Picatinny NJ 07806 United States

In this work we introduce and describe optimal sets of survivable paths defined on an undirected simple graph G. An optimal set of survivable paths in G corresponds to a set of mesh-restored lightpaths in an optical network that minimizes the number of optical channels. We present several fundamental properties of optimal sets of survivable paths in G.

X-ray luggage inspection systems play an important role in ensuring air travelers' security. However, the false alarm rate of commercial systems can be as high as 20% due to less than perfect image processing algorithms. In an effort to reduce the false alarm rate, this paper proposes a combinational scheme to fuse, de-noise and enhance dual-energy X-ray images for better object classification and threat detection. The fusion step is based on the wavelet transform. Fused images generally reveal more detail information;however, background noise often gets amplified during the fusion process. This paper applies a background-subtraction-based noise reduction technique which is very efficient in removing background noise from fused X-ray images. The de-noised image is then processed using a new enhancement technique to reconstruct the final image. The final image not only contains complementary information from both source images, but is also background-noise-free and contrast-enhanced, therefore easier to segment automatically or be interpreted by screeners, thus reducing the false alarm rate in X-ray luggage inspection. © 2005 IEEE Computer Society.

This paper presents a novel gait generation technique for legged robotic systems which utilizes the Dynamic Capability Equations. The method consists of calculating the acceleration capability early in the simulation to determine a specific configuration which easily allows a gait to be generated. This position is calculated to most effectively arrest any body center-of-mass momentum upon impact and allows the system to continue travelling in the desired direction without suffering detrimental effects from the impulse forces normally encountered when walking. © 2005 IEEE.

A design study of a cable-driven hexapod

A design study of a cable-driven hexapod

作者： Go, Yanto Bowling, Alan Department of Aerospace and Mechanical Engineering Robotics and Dynamic Systems Laboratory University of Notre Dame Notre Dame IN 46556-0539 United States

ISBN: (纸本)0780389123

This article illustrates the use of dynamic performance analysis in the design of legged robots, specifically hexapods. This is accomplished by comparing the dynamic performance of a cable-driven hexapod to that of a more conventional design in which the actuators are mounted at the joints. By integrating the actuators into the torso and through the use of cable transmission, the mass and inertias of the legs are reduced in order to attain the high accelerations and backdrivability. The dynamic performance described herein is bounded by the actuator torque limits and the no-slip condition at the ground contact points. The result is a description of how well each hexapod can accelerate its torso without causing slippage at the ground contact points. Although somewhat mixed, the results show some advantage to the use of a cable-driven transmission. © 2005 IEEE.
