A number of different load conditions including nonlinear and time-varying ones are used to investigate the performance of the proposed control algorithm on a laboratory setup that regulates the speed of a DC motor.

The friction model discussed in this paper aims at improving the existing rigid robot model. The losses in joint transmission originate in friction between moving parts in contact or between moving parts and the ambient fluid. Commonly, robotic identification models represent joint transmission friction force as a viscous friction force, depending on the velocity, added to a constant dry friction force. However, the tribology science field teaches that friction in general depends on load (reaction force normal to the contact surface). It is important to consider this dependence when variable loads are applied on the joint transmission (external payloads, inertial load and gravity forces). Since these mechanisms are lubricated, it is appropriate to refer to the Stribeck curve (rather than Coulomb). This curve describes the friction coefficient as being dependent on a parameter (Hershey) combining the velocity and the load. This paper proposes a new expression of the load-velocity friction model, in order to identify a serial n degrees of freedom (DOF) robot. The friction force of this new inverse dynamic identification model is a linear function of both inertial and external forces. An experimental validation on an industrial manipulator used as a force feedback telerobot in nuclear plant concludes this paper.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125668075","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}

Our approach uses active compliance to overcome difficulties that are crucial for the realisation of symmetric gaits, i.e. force equalization, disturbance rejection and impact absorption. We present a scheme for the compliant control of each leg that is based on a virtual spring abstraction. This active compliance scheme allows us to greatly vary the dynamical behaviour of the system on-the-fly, without altering the physical characteristics of the robot, by changing the parameters of the virtual springs. This way we are able to evaluate a wide range of trotting gaits with varying parametrizations. We report results of robust trotting in various speeds and push recovery in simulation, and continue with results of actively compliant trotting on the real quadruped robot. We further discuss difficulties and limitations with the implementation of such dynamic gait controllers on the real system.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126308876","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}

Such tasks are commonly solved by means of iterative learning control strategies as well as by the concept of repetitive control. Most of these before-mentioned techniques are designed in such a way that the linearity of the underlying system model is exploited. If a dynamic system is nonlinear, techniques for gain scheduling, corresponding to an online adaptation of a quasi-linear system model, are commonly applied. However, such adaptation strategies, depending on state measurements or estimated variables, have to be derived specifically for each problem at hand. Therefore, a sensitivity-based control approach is presented in this paper that can be employed for tracking control of both linear and nonlinear dynamic systems in spite of non-modeled disturbances. This control strategy makes use of a real-time capable sensitivity analysis of dynamic system models and comprises aspects of model-predictive and iterative learning control. The applicability of the corresponding algorithm is demonstrated in simulation and experiment for a distributed heating system.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126406227","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 walking guide system must detect an obstacle's distribution in walking space including hanging and/or protruding obstacles, and provide useful feedback for safe walking. In this study, we investigate the applicability of a tactile display to the walking guide. The obstacle information is transmitted to the palm by tactile stimulation. The three dimensional (3D) detection of an obstacle's distribution using ultrasonic sensors, the fabrication of a tactile stimulator using vibration motors, and the mapping of the detected results to an array-type tactile stimulator are proposed. An experiment on the recognition of an obstacle's distribution via tactile stimulation is performed to evaluate the possibility of a walking guide. In the experimental result, the average recognition rate was 95.14 % (5.73, standard error).","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113977659","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}

Opportunities that robots touch directly on humans have been increasing. However, active actuators are often used in order to generate force and perform their tasks and they have possibility of hurting people around. Then, stable passive actuators would be substituted for active ones. Passive actuators will not generate force by themselves. Only when external force acts on them, they generate resisitive force. Considering these properties, passive actuators are stable actuators and appropriate for the human society because they would be little risks for humans when they are loss of control. In this paper, the passive actuator is constructed using magnethorheological (MR) fluids and is nominalized based on disturbance observer in order to become robust for inner state of MR fluid and to be regarded as an active actuator. By experiments, the validity of the proposed method is verified.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128914350","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}
