On March 11, 2011, a massive earthquake (magnitude 9.0) and accompanying tsunami hit the Tohoku region of eastern Japan. Since then, Fukushima Daiichi Nuclear Power Plants have been facing crisis due to loss all power that resulted from meltdown accidents. Three buildings housing nuclear reactors were seriously damaged hydrogen explosions, and, in one building, reactions became out control. It was too dangerous for humans enter inspect damage because radioactive materials also being...
Abstract We report recent results from field experiments conducted with a team of ground and aerial robots engaged in the collaborative mapping an earthquake‐damaged building. The goal experimental exercise is generation three‐dimensional maps that capture layout multifloor environment. took place top three floors structurally compromised building at Tohoku University Sendai, Japan was damaged during 2011 earthquake. provide details approach to form generated by individual as team. conclude...
Disaster rescue is one of the most serious social issue which involves very large numbers heterogeneous agents in hostile environment. RoboCup-Rescue intends to promote research and development this socially significant domain by creating a standard simulator forum for researchers practitioners. While intuitively appealing as scale multi-agent domains, it has not yet given through analysis on its characteristics. In paper, we present detailed task elucidate characteristics necessary systems domain.
On March 11, 2011, a massive earthquake and tsunami hit eastern Japan, particularly affecting the Tohoku area. Since then, Fukushima Daiichi Nuclear Power Station has been facing crisis. To respond to this crisis, we considered using our rescue robots for surveillance missions. Before delivering robot TEPCO (Tokyo Electric Company), needed solve some technical issues add functions Therefore, began redesign project equip disaster response gave us two specific One was explore inside outside of...
Disaster rescue is one of the most serious social issues that involves very large numbers heterogeneous agents in hostile environment. The intention RoboCup Rescue project to promote research and development this socially significant domain at various levels, involving multiagent teamwork coordination, physical for search rescue, information infrastructures, personal digital assistants, a standard simulator decision-support systems, evaluation benchmarks strategies, robotic systems are all...
In this paper, we discuss the development and proliferation of robot test arenas that provide tangible, realistic, challenging environments for mobile researchers interested in urban search rescue applications other unstructured environments. These allow direct comparison robotic approaches, objective performance evaluation, can ultimately a proving ground field-able systems such as those used at World Trade Center collapse. International competitions using these require robots to negotiate...
A redundant wire-driven parallel robot, the WARP manipulator, is a new robot mechanism which suitable especially for high speed assembling of lightweight objects such as semiconductors. In this paper, manipulator was designed from viewpoint working space by considering conditions that travelling plate must be abbe to generate arbitrary amounts force and moment wires are not in contact. Simulation results proved validity design procedure described. prototype constructed. The kinematic...
Disaster response, especially fire-fighting and rescue, is highly risky for firefighters engaged in action. As a result, many robots intended have been proposed. However, it difficult them to directly access fire sources because their mobility limited. Specifically, existing are large heavy. Therefore, we propose novel hose-type robot, which can fly into the source via water jet. First, control reaction force stable flying, developed nozzle module. By combining two nozzles whose outlet...
Abstract Continuum robots can enter narrow spaces and are useful for search rescue missions in disaster sites. The exploration efficiency at sites improves if the simultaneously acquire several pieces of information. However, a continuum robot that information to such an extent has not yet been designed. This is because attaching multiple sensors without compromising its body flexibility challenging. In this study, we installed small distributed manner develop continuum-robot system with...
This paper introduces the RoboCup-Rescue Simulation Project, a contribution to disaster mitigation, search and rescue problem. A comprehensive urban simulator is constructed on distributed computers. Heterogeneous intelligent agents such as fire fighters, victims volunteers conduct activities in this virtual world. real world interface integrates various sensor systems controllers of infrastructures cities with Real-time simulation synchronized actual disasters, computing complex...
This paper presents a useful tactile display method that can control multiple sensations such as roughness, pressure, and friction using simple vibratory stimulations. Our concepts are based on two points: frequency range selection for making selective stimulation different receptors types timing of the in response to hand movements. The stimulations were realized by selecting reactive frequencies temporal characteristics receptors. For representing roughness sensation, vibrating modulated...
