A kinetic model of the lower limbs during walking was established, according to the actual posture of human movement in this paper. Based on the Lagrange equation the required joint torque was calculated according to the information of angle, angular velocity and angular acceleration of lower limbs' joints.

Applying the structural dynamic equations of blades, the aeroelastic model of the rotating rotor and the numerical simulation method of the deflections are presented under the aerodynamic loads and centrifugal forces. Coupling the aerodynamic characteristics and the structure stress, the flapwise and edgewise loads, deflections and accelerations of the rotating blades are calculated and plotted. Finally, one 5MW wind turbine rotor is chosen that the aerodynamic loads and output power are simulated. The bending displacement and vibration response are investigated and compared between different wind speed and working time to prove the accuracy and reliability of the model presented in this paper.

This paper present a multi templates based strategy for human detecting and tracking with a mobile robot. This method first determines the coarse location by using adaptive template matching algorithm (ATM) based on head-shoulder. Then, a multi-templates based method is presented to locate the person precisely. Multi templates considering the pose changes are obtained to represent the person. 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. Finally, the method is evaluated on a mobile robot in complex environment. The experiment result shows that our method performs well when there are unclear disparity image and pose variations.","PeriodicalId":286366,"journal":{"name":"2015 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"235 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":"114276484","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, current hyper redundant robots are designed with limited agility because a joint in hyper redundant robots can only rotate around a fixed axis. 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}

In addition, the thermal distribution on the peltiers with different thickness copper film were measured through the line average temperature measuring method. The cooling rate of the PCR chip with coppering Peltier also was tested according to the PCR program. The results of the simulation and measurement showed that the CTIBSD method could greatly improve the thermal performance of Peltier and the PCR time of the PCR chip could be reduced by the increasing of the heat transfer rate.

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}

Hereby, an ISA evolutionary model based on cellular automata is proposed to study the ISA transition and spatial distribution. The simulation experiments show the average level of ISA in group is fluctuating with individual movement, interactions and security training etc., and the ISA distribution has features of plasticity, sociality, diffusibility and relative independent ability.

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}
