The demand for monitoring from high points is increasing to support remote control and accurate monitoring. Unmanned ground vehicles with long arms are used to achieve long-term and accurate monitoring. The use of convex steel tapes is effective for achieving both high strength and lightness of the arm, which prevents the robot from collapsing or the arm from falling off. However, the previously proposed...
A one hand drive wheelchair with power assist mechanism is developed. In this investigation, we propose a simple and useful manipulation torque detection method which yields wide detection areas with uniform distribution of stress. This method can be applied to a one hand drive wheelchair with complicated structure of manipulation mechanism with three rings. Moreover, even if the grasping position...
This paper addresses the problem of feature-based robot localization in large-size environments. With recent progress in SLAM techniques, it has become crucial for a robot to estimate the self-position in real-time with respect to a large-size map that can be incrementally build by other mapper robots. Self-localization using large-size maps have been studied in literature, but most of them assume...
This study provides an investigation of scalability of mobile robot localization. In recent years, inference algorithms based on map-matching have proved their superior performance in large-scale environments. In this paper, the scalability is augmented by an ANN retrieval of high-dimensional descriptive features. The proposed algorithm is then exhaustively evaluated using large-size real maps, including...
This paper proposed a small and light actuator based on an easy ON-OFF control to movement walking robot. We named a flexible, flat plate to FFP actuator as an actuator of a flexible locomotion robot. The FFP actuator is a versatile actuator that mechanically obtains flexible displacement by combining functional materials like the shape-memory alloy with a simple lamina structure lightly not broken...
A novel scheme of spot size converters is proposed and successfully demonstrated between high refractive index (4.0%) waveguides and conventional single mode fibers, whose coupling loss is evaluated to be 0.3 dB.
Assembly Instruction Manuals usually consist of both explanation and illustration. An expart who has rich knowledge on mechanical assemblies is able to under stand illustration without reading explanation. It is, how ever, difficult for a novice to read an instruction manual without referring to both of them. People may probably read explanation and see illustration alternately. It is difficult to...
