This paper presents a flywheel energy storage system (FESS) for load-leveling. In order to improve the efficiency and the lifetime, a permanent magnet synchronous motor, a spherical spiral groove bearing (SSGB) and a magnetic assist system are applied to the prototype. The variable thrust by the proposed magnetic assist system is evaluated. As a result, the variation of thrust becomes 16.4%. In addition,...
This paper presents a knowledge model of everyday objects for semantic grasp. This model is intended for extracting the grasp areas of everyday objects and approach directions for grasping when the 3D point cloud data and the intended purpose are given. Parts that make up everyday objects have functions related to their manipulation. We therefore represent everyday objects in terms of connected parts...
