Pneumatic artificial muscles not only have a high power to weight ratio, but also have a high affinity with the human body due to their use of air pressure. However, pneumatic artificial muscles have a slow stretch response rate due to their viscous properties. Therefore, earthworm type mobile robots and wearable assistive devices using artificial muscles move slowly and have difficulty assisting human movements. We focus on the mechanism of force generation using the distortion of the exoskeleton, similar to what is seen in the punching of a mantis or the jumping of a grasshopper, as a countermeasure against the delay in the response rate of the artificial muscle. In this study, we propose a new mechanism to generate a shooting force by incorporating an element similar to an exoskeleton spring into the antagonistic drive mechanism of an artificial muscle. We designed and developed a prototype then operated it and measured the impulsive force. It was found that the developed mechanism showed similar joint movements through muscle contraction to those of mantis shrimp and grasshoppers. Furthermore, it was shown that the time constant for the maximum strike force was 6.6 N and 63.2 % of the maximum impulsive force was 0.183 s.","PeriodicalId":314060,"journal":{"name":"Robots in Human Life","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130778375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been widely acknowledged as an effective technique particularly for NDE of composite materials to detect subsurface defects such as delamination, disbond, cracks and impact damages. However, the use of shearography to inspect wind turbine blades (WTB) on site a wind tower is not proven, because a WTB is in constant vibration due to wind even when it is parked on a tower at low-speed wind. To address the problem, we aim to attach the shearography sit onto the WTB during inspection when the WTB is parked, the relatively motion between the shearography and the WTB is minimized within the tolerance of the shearography system. The ultimate goal is to develop a robot assisted shearography system able to inspect the WTBs on-site through remote control by operators on the ground (for onshore wind turbines) or on a vessel (for off-shore wind turbines), so that there is no need to send humans to the wind tower via a rope to do the inspections. This paper reports part of our research work surrounding the new shearography that is designed for integration with a robotic climber for on-site WTB inspection. It includes the principle of shearography, comparison of shearography with other NDE technologies, robotic application, experiments validation for fringe patterns, and description of post processing algorithms.","PeriodicalId":314060,"journal":{"name":"Robots in Human Life","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126253024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
