In the context of RoboCup it is very important that the robots recognize the field, the ball and the competitors. This recognition can be done using the objects’ colors. All approaches to color classification are dependent on the quality of the provided camera picture. A manual optimization of camera parameters is time consuming and we noticed that optimal parameters can be very different from manually chosen ones. Therefore we developed a general automatic approach to optimize camera parameters for color classification, based on evolutionary algorithms.","PeriodicalId":338050,"journal":{"name":"2019 4th Asia-Pacific Conference on Intelligent Robot Systems (ACIRS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115126481","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}

This bio-signal is extracted from gaze motions by attaching electrodes to the skin around the eye. This paper presented the design and development of gaze-motion controlled adaptive virtual keyboard. The keyboard has the ability to arrange character layout based on specified frequency of a character. The designed virtual keyboard has 45 keys that comprising 26 letters, 10 numerals, 4 symbols, a space, a delete, an enter, a return and a central point key. The keyboard layout has six zones. Characters in the same zone have equal distance to the central point. The distance is the least gazing that possible to move from the central point to the character. The most frequently used character will shift to the shortest distance position. Seven paragraphs were typed using this virtual keyboard. The keywords of each paragraph are ‘bukittinggi’, ‘zimbawe’, ‘andalas’, ‘sukarno’, ‘randang’, ‘kapal’ and ‘dokter’. The performance of the adaptive virtual keyboard was evaluated using these seven keywords. Results shows that the number of gaze motion required to type the keyword after the re-arrangement of layout decreased about 27%. This adaptive ability can reduce the number of gazing to prevent eye fatigue.","PeriodicalId":338050,"journal":{"name":"2019 4th Asia-Pacific Conference on Intelligent Robot Systems (ACIRS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114902774","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}

Secondly, the robot service scheduling algorithm based on Genetic Algorithm (GA) is proposed to make a more efficient service scheduling. Lastly, the voice recognition service is used to verify the availability and high services accuracy of the platform. Cloudsim is used to test a number of performances on the cloud platform comparing with the traditional Service Oriented Architecture.

Facial expression recognition has been applied in various fields and it has become an increasingly interesting research field in the recent years. A significantly important aspect of facial expression recognition is the feature extraction process. Hence, this paper presents a new facial feature extraction method for expression detection. The proposed method is based on the computation of distances and areas that are formed by two or three facial points provided by Kinect v.2. This computation is used to obtained the facial features. Then, the features which potentially can be used to distinguish happiness, disgust, surprise and anger expressions, will be selected. From the results of the extraction process, a total of 6 facial features were formed from the 12 points that are located arround the mouth, eyebrows, and cheeks. The facial features were later applied as inputs into an artificial neural network model built for expression prediction. The overall result shows that the proposed method could achieve 75% success rate in correctly predicting the expressions of the participants.","PeriodicalId":338050,"journal":{"name":"2019 4th Asia-Pacific Conference on Intelligent Robot Systems (ACIRS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130113604","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 experimentally demonstrated that microspheres have the ability of super-resolution imaging. Here, we report a probe-combined microsphere which consists of a barium titanate microsphere with the diameter of $50 sim 100 mu m$ and a probe. The finite element method is performed by the COMSOL Multiphysics software to confirm that the probe has no influence on the microsphere imaging. When the probe-combined microsphere was installed on a three-dimensional precision translation stage, it can be moved to the desirable area to capture the tiny feature of rat liver slices and the appearance of cells. What’s more, the probe-combined microsphere can adsorb the cells on the back of the microsphere, and thus it can be used as a tool to pick up cells. Another probe can operate the cells and morphological changes of cells can be observed through the microsphere at the same time.","PeriodicalId":338050,"journal":{"name":"2019 4th Asia-Pacific Conference on Intelligent Robot Systems (ACIRS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127676242","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}

This kind of robot can be used widely in schools, universities and public services. The humanoid robot should consider the style of questions and conclude the answer through conversation under unreliable automatic speech in noisy environment. In our scenario, robot will detect user’s face and accept commands from the user to do an action, where the answer from user will be processed to the Google Translator and the result will be compared with vocabularies defined on the system.
