One cause of large changes in torques is the presence of discontinuities in the constraints that the robot must satisfy, such as the avoidance of an obstacle or the breaking of contacts with the environment. In this paper, a model predictive control (MPC) approach to approximate constraints that can be predicted over a finite horizon is proposed to minimize the derivative of torques during robot control. The proposed method does not directly modify the desired task trajectory but the constraints to ensure that the worst case of changes in torques is well-managed. From the simulation results on the control of a Kuka LWR robot, it is shown that our approach significantly decreases the maximum derivative of joint torques for both force and acceleration task control examples.","PeriodicalId":325536,"journal":{"name":"2015 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128641050","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}

An RFID system using multiple RFID readers and high density RFID tags has already been applied to an indoor mobile robot self-localization. However, the system production cost is relatively high. To reduce the production cost of the system while maintaining the self-localization performance, we redesign two new RFID systems configured with 20 RFID readers and 5 RFID readers enlarging the size of an RFID reader antenna. Particularly, a new likelihood function of the tag detection with the redesigned large size RFID reader antenna is proposed for Monte Carlo Localization (MCL). Furthermore, we come up with a novel arrangement of RFID tags installed in a hexagon pattern. The new arrangement of ID tags enables both low cost ID tag installation and high performance of self-localization. We examine the performances of robot self-localization with less RFID readers and lower density RFID tags installed on the floor based on MCL(Monte Carlo localization). The simulation demonstrates the validity of our proposed configuration of the RFID based self-localization.","PeriodicalId":325536,"journal":{"name":"2015 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115398625","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 legged robot continues running at equal speed, if total mechanical energy is conserved. However, the faster the average speed is, the larger the energy loss is. A legged robot walks at a regular speed when input energy and energy loss are balanced. If the energy loss per step could be reduced by analyzing the energy outflow from the robot phase by phase, the resulting balanced speed would be faster. The possible energy loss involves viscosity, friction and impact with the ground, negative work (to control the joint angles) of the actuators, and so on. The purpose of this study is to establish a control method for quadruped robots, by which the walking speed is greatest with limited input energy. We aim at clarifying the mechanism of the flow of mechanical energy: translational and rotational kinetic energy of each link, elastic potential energy of each elastic element, and gravitational potential energy of each link.","PeriodicalId":325536,"journal":{"name":"2015 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115471377","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}

To reduce the influences from the invalid data, a neural network based on each empirical data is established. The training data are clustered based on the empirical data. The way of choosing a neural network to compute the racket parameters depends on the comparison between the new coming data and the empirical data.

In this study, an optimized non-reciprocating planning method by planning the posture angle of the supporting paddle is focused to improve energetic efficiency of this gait. Relationship between the posture angle of the supporting paddle and actuation forces on the paddle is analyzed in the state of equilibrium. Standing on the ground vertically is found to be an optimal posture for the supporting paddle to achieve minimum quadratic sum of the actuation forces. The planning method that considers the optimal posture angle of the paddle and the stride of the gait is established and verified in simulations. Calculated specific resistance confirms that the proposed method can improve the energetic efficiency of the non-reciprocating legged gait.","PeriodicalId":325536,"journal":{"name":"2015 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115751741","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 this paper, how the influence of a Simultaneous Localization and Mapping (SLAM) algorithm is had in featureless environments without kidnapping recovery algorithms following a certain locomotion, such as the serpentine locomotion, is presented. In a comparison between two similar SLAM algorithms, how a key process, which is only present in one of SLAM algorithms, can affect the mapping performance, is shown. Furthermore, tests modifying the parameters of this process have been done. Also, simulations while changing the grid size of the map were conducted.

However, OLP is not yet commonly and widely used in applications, since commercial OLP systems are very expensive, with prices even much higher than those of robotic systems themselves. Simple but effective OLP systems are desired, and such systems may be made based on other commonly used CAD systems. We have developed a robotic OLP system, which we called RobSim, based on SolidWorks and with Microsoft Visual Studio 2010. RobSim is developed as an add-on tool for the commonly used CAD software SolidWorks. With this OLP system, an object can be made, imported or modified in the conventional mode in SolidWorks environment, and various trajectories for a robot can be easily and conveniently defined and modified in the same environment. Trajectory interposition, kinematic computation, dynamic and graphic simulation can be conducted. Finally executable codes can be generated for the robot to perform tasks. In this paper, the development of RobSim is demonstrated. Specifically, the architecture of RobSim, the method for extracting position and orientation from a pre-defined path on an object for the robot tool, and path transformation, are presented. Simulation and experiments are also conducted to verify the effectiveness of the OLP system.","PeriodicalId":325536,"journal":{"name":"2015 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127284810","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}
