While wireless sensor network aided robots lend humans a hand in accessing to certain difficult and/or otherwise unreachable areas, the robots may face challenges in locomotion, object discovering, searching and tracking among many demanding tasks. The unreliable wireless communication and possible components failures of wireless sensor nodes coupling with the noises in the uncertain environments...
This paper presents the evaluation results for conventional methods that can be used for vision-based localization. An Active Scope Camera is a very thin snake robot and can be used as a rescue robot for search and rescue missions. Self-position estimation of the Active Scope Camera is important for efficient search. Nevertheless, using sensors for this purpose hinders the movement and maneuvering...
When rescue robots navigate in a rough terrain, significant vibration of the video occurs unavoidably and a video stabilization system is proposed in this paper to reduce the disturbance on the visual system of the present rescue robots. The Kalman filter is applied to estimate the motion vector of the robot and the false estimation occurrence can be thus greatly reduced by applying analysis of correlation...
This research is concerned with a rubble withdrawal method using force sensors attached on fingertips in order to not break down rubbles during operating for advanced autonomous rescue robots. In rescue fields, mass, shapes, materials and so on of rubbles are unknown. Thus, it is necessary to recognize or estimate a good grasping position without breaking rubbles case by case at the time. Therefore,...
