Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, sensing technology that appropriately detects a person's intention and state from surface EMG signals generated when trying to move muscles has been used in the development of power assist robots that assist human movements along with the development of machine control technology. Various types of power assisted robots have been developed according to the intention and state of a person, such as a care robot that assists a person in walking and a work robot that assists in lifting a heavy object. Therefore, in this research, we focused on the unstable state due to slippage when holding an object, which is a major obstacle in the movement of a person to hold an object stably. The purpose of this research is to sense the unstable state due to slippage, which is necessary for the development of a power assist robot that supports the holding of objects before dropping. In the experiment, we prepared objects with different slips and measured myoelectric potentials when a person was holding them, and investigated whether there are any features unique to holding a slipping object. It was found that there is a significant difference in the muscle activity of humans and the correlation between the main muscle and the antagonist muscle.
