This study was undertaken to establish basic technologies and knowledge of aerial photography and its application to support safe rowing. For the water sport of rowing, managers and coaches use a motorboat to follow a rowing boat for coaching and safe rowing observation. Utilization of a motorboat gives rise to numerous problems in terms of pulled waves, narrow visual ranges, limited tracking of boats...
This paper presents automated navigation control of an Unmanned Aerial Vehicle (UAV) based on visual data gathered by onboard camera. With depletion of easy resources and health, safety and environmental (HSE) challenges in exploiting newly found resources in hostile conditions are forcing oil and gas companies to look for robotic solutions for their problems. Pipelines carrying inflammable and toxic...
This paper is aimed at finding the optimal locations of collocated actuator and sensor pairs for active vibration control of cable-network antenna reflectors. The front cable net of the antenna is considered as the control plant. The optimal criterion for placement of actuator and sensor pairs is to choose locations that simultaneously maximize the H2 norms of each dominant mode, and simultaneously...
To develop a mechanism that will smoothly support the standup motion of elderly people, we reconsidered the operation-start timing of our previously developed device using a measurement apparatus. In the experiments with elderly subjects, the mechanism did not work as well as it did with younger subjects. For younger subjects, the floor's reaction force decreased when the support mechanism was used,...
The number of children diagnosed with autism spectrum disorders (ASD) is on the rise internationally. Most of these children require some degree of special education provision, whether they are educated in regular or specialized settings. Most if not all children with ASD exhibit some impairments with social communication skills. Yet, these skills are associated with outcomes in cognitive functioning...
Human detects the external tactile stimulation using mechanoreceptors under the skin. There are various kinds of mechanoreceptors in the skin. In this paper, the proposed sensor mimics Ruffinis corpuscle which detects shear force. The sensor consists of Ecoflex® 0050 as a substrate and silver nanowire (AgNW) in the shape of typical strain gauge as a sensing element. The Ecoflex® 0050 was chosen as...
