This paper proposes a basic near-environmental recognition framework based on groping for risk-tolerance disaster response robot (DRR). In extreme disaster sites, including high radiation and heavy smog, external sensors such as cameras and laser range finders do not work properly, and such sensors may be broken in accidents in the tasks. It is hoped that DRRs can continue to perform tasks, even if...
Disaster response robot with four arms and flippers OCTOPUS has high mobility and task-execution capabilities. Owing to the higher number of degrees of freedom, OCTOPUS is controlled by two operators, however this kind of robots is inherently difficult to be operated. To design easy-to-use human machine interfaces and intelligent control systems, we need to analyze and quantify a reasonable operation...
Human communicative behavior is both dynamic and bidirectional. This study aims to analyze such behavior by conducting imitative interactions between human subjects and a humanoid robot that has a neuro-dynamical system. For this purpose, we take a robot-centered approach in which the change in robot performance according to difference in human partner is analyzed, rather than adopting the typical...
In this paper, a practical system for detecting (identifying the on-off state of) the load applied to a construction manipulator (front load) by using a hydraulic sensor is presented. Such an industrial application requires high accuracy and robustness considering the uncertainty in hydraulic pressure-based force measurement. Therefore, our system is composed of (a) identifying the dominant error...
Wheelchair mounted robotic arm is an assistive device designed to help physical disabled people to recover some manipulation capabilities in activities of daily livings. During task execution of wheelchair mounted robotic arm applications, both the requirement of safety and task accomplishment has to be satisfied. We have developed a wheelchair mounted robotic arm with mechanical gravity compensation,...
