Human motion recognition systems play an important role in improving the ability of robots to support human life. This paper proposes a novel motion recognition method based on haptic data (i.e., position and force information). First, haptic data are obtained using a bilateral control system. Second, the haptic data are divided into action components,(More)
In this paper, a novel structured planar direct drive motor for use in industrial equipment is proposed. The characteristics are its flat structure compared to conventional 2 Degrees Of Freedom (DOFs) motors and realization of 2 DOFs motion within one device. The structure of the planar motor consists of two sets of coils placed perpendicularly and a(More)
Power factor in mechanical system is a new concept to express characteristic in mechanical system. It defines dynamic behavior of the impedance characteristic in the motion. However, conventional derivation method requires short-time Fourier transformation in order to consider random input in mechanical system as a combination of sinusoidal waves. This(More)
BACKGROUND Diacylglycerol kinase (DGK) is an enzyme that converts diacylglycerol to phosphatidic acid. Previously, we reported that DGKβ knockout (KO) mice showed mania-like behaviors such as hyperactivity, reduced anxiety, and cognitive impairment. Furthermore, lithium ameliorated the hyperactivity and reduced anxiety of DGKβ KO mice. In this study, we(More)
Two-Step Test is now widely used to evaluate the locomotion ability of human in Japanese biomechanical clinical hospitals. It is a test in which Two-Step Value is calculated by dividing a subject's height by the maximum distance of his/her two steps of walking. The test was developed by Hirano and Muranaga in 2003 to conveniently predict human's walking(More)
