For each template, the mean-shift is proceeded. Then, the accurate position is obtained by fusing the results of the Mean-shift from all the templates. After detecting the person, the templates are updated by considering the likelihood of the tracking results and the old templates.

In this paper, we propose an ultimate hyper redundant robotic arm design in which ever joint is omnidirectional, thus pushing the boundary of current hyper-redundant robots in terms of accessibility and agility. In the proposed design, each joint in the hyper redundant robot is an omnidirectional ball joint. The rigidity of each ball joint is controlled by shape memory alloys (SMA). The rotation of the ball joints is also controlled by shape memory alloys. In order to demonstrate the feasibility of the proposed ultimate hyper redundant robotic arm, a prototype has been made and illustrated in this paper.","PeriodicalId":286366,"journal":{"name":"2015 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114759403","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}

Work efficiency is improved by using plastering machine and the labor intensity is reduced. To improve the quality of plastering using the plastering machine, a new measurement and control method is proposed in this paper. This method utilizes the laser sensor to measure the distances between the plaster board and the wall, calculates the errors of the bracing pieces perpendicularity and the deflection angle of plaster board, and compensates the error by trajectory planning. In addition, the principle of laser triangulation is analyzed and the types of measurement, including direct and oblique measurements, are also illustrated. The oblique measurement based on laser triangulation is adopted in the system due to its higher resolution and good feasibility. According to the space geometry relation, the errors are calculated accurately. Furthermore, a scheme of error compensation is addressed based on a two nested loops structure. Each of these loops implements a Proportional Integral (PI) controller. With the compensation scheme, the trajectory of plaster board can be determined and tracked to verify the plaster results. The theoretical analysis is validated by an extensive set of numerical simulations which shows the performance of the proposed control system.","PeriodicalId":286366,"journal":{"name":"2015 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127592952","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}

However, it is still rather challenging to explore if the robot motions are effective or not as non-verbal cues. For this purpose, this paper presents a perceptual evaluation of robot motions in the context of a multi-party teleconference. Our main focus is on analyzing the relationship between the robot motions and the motivation to speak by testing the following two hypotheses. (H1) There are some kinds of robot motions that are more effective for expressing the motivation to speak than others. (H2) The intensity of robot motions is correlated with the perceived strength of the motivation to speak. In a preliminary experiment with five subjects, we confirmed that our hypotheses were reasonable and we formulated the robot motions that were used in the experiments. In each of 10 evaluation experiments, three participants attended a teleconference for about 30 minutes and one of them (called a subject) evaluated the robot motions in real time. The evaluation results from a total of 10 subjects in 10 experiments demonstrate that both hypotheses can be partly upheld.","PeriodicalId":286366,"journal":{"name":"2015 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126841337","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}
