The DCI is a small number of color information that is only calculated at narrow areas around a user's (guided person's) joint positions obtained via KINECT on a mobile robot. The SPI method includes not only the person's skeletal information but also the DCI. This method can identify the specific user in real time. As a result, even if the mobile robot loses the user temporarily when there are many people present, it can find the user properly and promptly. In addition, it can maintain the distance to the user according to the walking speed. Experiments that show the accuracy of the SPI method using the DCI and the example of guidance to the destination are presented.","PeriodicalId":426468,"journal":{"name":"2012 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128716512","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 order for the exercise machine that can facilitate the moderate aerobic exercise for users who cannot do real cycling, we have developed the virtual reality bike (VR Bike) with a cylindrical MR fluid brake. The aim of this paper is to describe (1) the development and integration of the total system of the VR Bike, and (2) the implementation of the controller for the pedaling torque in the straightway driving with slopes. The cylindrical MR fluid brake was connected to the pedal of a belt-driven bicycle and used to control pedal resistances depending on the environment of the virtual world. We formulated the torque characteristics of the brake and controlled the pedaling torque with the input current. Data of a 3D map were loaded in the VR Bike system and a subject ride a bike in the virtual world. The main controller calculated the dynamics of the bike and determined the pedaling resistance. Time profiles of the traveling speed and pedal torque during climbing up and down the slope were evaluated. Though quantitative evaluation has not conducted, the proposed system changes the pedal resistance depending on the conditions of the bike.","PeriodicalId":426468,"journal":{"name":"2012 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127239633","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}

Its two operation modes are based on head movements: Mode 1 uses only one head movement to give the commands, and Mode 2 employs four head movements. An EEG device, namely Emotiv EPOC, has been deployed in this HMI to obtain the head movement information of users. The proposed HMI is compared with the joystick control of an EPW in an indoor environment. The experimental results show that Control Mode 2 can be implemented at a fast speed reliably, achieving a mean time of 67.90 seconds for the two subjects. However, Control Mode 1 has inferior performance, achieving a mean time of 153.20 seconds for the two subjects although it needs only one head movement. It is clear that the proposed HMI can be effectively used to replace the traditional joystick control for disabled and elderly people.","PeriodicalId":426468,"journal":{"name":"2012 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130525983","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}

The architecture described consists of two main parts being strongly interconnected. The first part is the development of an architecture based upon a high-speed fully switched Ethernet-network. This approach contrasts the way existing platforms were designed. The use of a switched Ethernet-network, instead of commonly used bus-systems, depicts a paradigm change in this field of robotics. The second part stipulates a strict decomposition of the robot module into various submodules. A powerful mainCPU, running a μClinux, represents the central entity of the architecture. It is supported by several peripheral microcontrollers, which perform low-level tasks and data preprocessing only. The submodules are treated as blackboxes, being independant from each other, only loosely coupled by a local SPI-bus. This results in a more robust and manageable system. As the number of submodules is not restricted, the architecture is very flexible. The employment of standards like POSIX and Ethernet severely eases the developmental process and further research.","PeriodicalId":426468,"journal":{"name":"2012 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132023727","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}

First, we describe the merits and demerits of the model-based external force compensation method proposed in our previous study and explain the necessity of this new control algorithm. Secondly, we explain this new control algorithm mathematically. In this new algorithm, each follower receives the motion errors estimated by the other followers with TCP/IP, which enables each follower to estimate its motion error by using the force applied to it. Moreover, this new algorithm also enables “intelligent Cooperative Autonomous Robot Transporters-type II (iCART II)” to transport many types of cars at a variety of places without the preliminary car transportation needed for identifying the model parameters of the external force. Finally, we conduct the transportation experiments of two types of cars for the comparison between this new algorithm and the conventional algorithm with the modelbased external force compensation method. These experimental results illustrate the validity of this new control algorithm.","PeriodicalId":426468,"journal":{"name":"2012 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130913105","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, in our society, many disable people cannot type by using keyboard. In order to assist them, we developed a shoe platform which senses the foot motion and use it as the input for the computer. In this system, we used force sensing resistors (FSRs) and a 3-axis accelerometer to detect foot movements. Based on these sensors, we analyzed human foot motions in different positions, and selected those with more comfortable motions when people sitting in front of the computer with a healthy attitude. To reduce the computational cost and power consumption, and enhance the real-time performance, we use the principle component analysis (PCA) for sensor reduction. Through PCA, we selected some important FSRs in this system. Also we compared two classification methods, chose two layer back propagation(BP) networks, to detect the foot movements for typing.","PeriodicalId":426468,"journal":{"name":"2012 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125400862","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}

A huge number of fluids has to be ejected due to the large variety of possible applications for inkjet printheads.

This inkjet printhead is manufactured in a batch process with rapid prototyping techniques in order to be able to be adapted to new boundary conditions in a time saving manner. The manufacturing time only amounts less than 30 minutes. The inkjet printhead is inserted into a support plate. Here, it is electrically as well as fluidically connected without any soldering or gluing processes. Heating elements, temperature as well as pressure sensors, and a fluid reservoir are integrated. The reproducibility of experiments is thereby given. Furthermore, printing fluids with solid-liquid phase transition is possible. The inkjet printhead can be changed within only one minute.","PeriodicalId":426468,"journal":{"name":"2012 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125519261","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}
