This paper introduces NASA's new free-flying robot, Astrobee, especially focusing on its avionics and perching subsystems. Astrobee is a cube-shaped autonomous robot designed for various missions on the International Space Station (ISS). Its major goal is to offload routine and repetitive work from the ISS crews and assist their science activities. Astrobee is also designed for scientists to use it...
At important structures of the plant, the oil is used to prevent mechanical wear. Because the oil is operated with very high temperature and pressure, oil leakage is generated occasionally. This is very difficult to monitor oil leakage. This is because the oil leakage is almost invisible. Therefore, oil leakage monitoring system is required. In this paper, we proposed the oil leakage monitoring system...
Recently intermodal transportation systems are significantly considered as advanced technique for future railroad logistics. These are aimed for particularly reducing complicated job process in the railroad based transportation and its relevant logistic cost in economic viewpoint. In this paper we suggest an aligning system using ultrasonic sensors, photo sensors, and CCD cameras for our intermodal...
This paper presents a new approach for hand rotation and grasping tracking from a single IR camera. For the complexity and ambiguity of hand pose, it is difficult to track hand pose and view variations simultaneously from a single camera. We propose a cylindrical manifold embedding for one dimensional hand pose variation and cyclic viewpoint variation. A hand pose shape from a specific viewpoint can...
When young children play, they often manipulate toys that have been specifically designed to accommodate and stimulate their perceptual-motor skills. Robotic playmates capable of physically manipulating toys have the potential to engage children in therapeutic play and augment the beneficial interactions provided by overtaxed care givers and costly therapists. To date, assistive robots for children...
As the robot soccer system becomes stabilized, it has been used as an educational platform with which various topics on mobile robotics can be taught. As one of key topics in the education of mobile robotics is computational intelligence-based navigation, this paper proposes a multiobjective population-based incremental learning (MOPBIL) algorithm to obtain the fuzzy path planner for optimal path...
