An adaptive control of a robotic system to prevent sleep apnea syndrome (SAS)

Sleep apnea syndrome (SAS) is known to be a serious problem in Japan. For example, the traffic accident rate of the SAS patient has approximately much 3 times in comparison with non-SAS patient. The device which it is simple and is easy to use, should be developed to prevent the SAS situation for the mild and moderate patients. In this paper, we develop an automatic judgement system of apnea state for a SAS patient and an adaptive control of a robotic arm system which stimulates turning over in bed for SAS patients only using non-contact type sensors.
