Technology to record and load human motions has recently attracted attention in manufacturing. The motion-copying system saves and reproduces human motions based on position and force information. In some cases, reproducing the saved motion is difficult. This paper focused on the environmental location to propose a method of reproducing the saved motion in different locations through the effective use of motion data memory. The proposed method was verified to be able to reproduce the force and position of saved motions.
Following audio and visual information, storing and reproducing of human motion is attracting attention. In order to realize this concept, motion-copying system has been proposed. The motion-copying system is based on the bilateral control composed of master and slave system. In this system, the motion of master system can be stored and reproduced by the only slave system. The useful application of motioncopying system is the education system. As the model case, it is considered that human touches the slave system in motionloading. However, the conventional motion-copying system is inappropriate for education and there are no index for evaluating the performance of system. Accordingly, this paper proposes novel indexes for motion-copying system. In addition, a motion-copying system for education is proposed. In the proposal, not only force, position information of master but also force information of slave are stored. The saved motion is reproduced by utilizing the motion data memory effectively. On the basis of these indexes, performances in conventional motion-copying system and the proposal are analyzed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
