Abstract
We are developing a remote arm-wrestling system in which two persons at different places can do arm-wrestling fighting due to the exchange of physical information such as position and force. The purpose of this study is to prototype and examine a wrist device for our Cartesian coordinate type remote arm-wrestling system. Then, we made a wrist device based on the force detection device that we produced last year, and examined what kind of operation could be produced and whether the install of the wrist device to the remote arm-wrestling system influences the operation of the device or not. Moreover, we performed an experiment for measuring the driving range of the wrist device in order to actually use it for arm-wrestling fighting.
