The controller is designed to address the problem of non knowledge of the dynamic parameters of the human limb since they differ from a person to another and the compensation for external disturbances. The proposed control scheme which supposes known only the upper bound of the inertia matrix of the system, guarantees high tracking performance when assisting wearers with shoulder, elbow and wrist joint movements. The reaching of the sliding mode as well as the tracking errors and the uncertainty bounds estimation convergence in finite time is proven. Simulations were performed to evaluate the performance and the efficiency of the proposed controller in tracking trajectories that correspond to passive arm movements.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132268178","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 proposed interface allows operator to navigate MAV in order to control and interact with uncertain indoor flying environments without using vision systems. The master interface combines bilateral shared control terms with the reflected remote interaction force fields mapped by two different types of force field algorithms as potential force field and spring-damper force field. The shared control strategy for the master comprises velocity signals of the remote MAV with the scaled position of the master haptic manipulator. The bilateral shared input interface for the slave is designed by combining scaled position of the master manipulator with the velocity of the remote MAV. The data transmission between ground station and remote vehicle are carried out by open internet communication network. In contrast with other haptic interface system, the proposed interface system only uses laser technology equipped with the slave MAV. Compared with potential force field based interface, the interface introduced in this paper provides better situational awareness about remote environment helping operator to navigate and control MAV for safe interaction with uncertain indoor dynamic environment. Experimental results together with comparative studies on laboratory made quadrotor MAV are presented to demonstrate the effectiveness of the proposed methods for real-time applications.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115969406","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}

Firstly, the position and velocity of the object need to be accurately predicted ahead of time. Secondly, feasible hitting poses need to be calculated. Thirdly, a fast motion planning algorithm for the robot needs to be implemented. Lastly, the inverse kinematics of the robot needs to be derived. In this paper, a six degrees-of-freedom UR5 robot is implemented to hit a freely flying ball. The dynamics of the ball is derived, and the analytical inverse kinematics model of the robot is given. The Gaussian Mixture Model (GMM) and Gaussian Mixture Regression (GMR) are used to encode human hitting demonstrations based on an autonomous dynamical systems model.

This paper presents a novel algorithm for dynamic manipulation on mobile platforms. A predictive algorithm synchronize robotic manipulators with a mobile platform. This is necessary when the manipulator or the mobile platform have huge dead-times. With the synchronization of the components the dynamics can be minimized to avoid any damage in the closed kinematic chain. With this novel approach for mobile manipulation precise tasks can be executed in large environments or while moving the platform. To synchronize the system the dead-times of the manipulator and the mobile platform have to be analyzed. The predictive algorithm is evaluated against an adaptive algorithm without dead-time knowledge. As hardware setup two LBR 4 are mounted on a KUKA Omnirob with Mercanum drives. The results are presented and discussed for the simulation and the real experiments.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131800877","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}

Accuracy of the force estimation suffers from friction caused by the rubber packing inside the trocar. This paper proposes a 3-DOF force sensor installed to the trocar support. It is possible to estimate the 2-DOF radial force applied to the instrument tip and the 1-DOF axial friction occurring in the trocar by using the 3-DOF force sensor. Accuracy of the estimation, however, deteriorates due to the reaction moment that occurs at the trocar support. An I-shaped force sensor is designed to reduce coupling effect which is caused by the reaction moment. Design parameters of the sensor are optimized to minimize the coupling effect by using ANSYS software. The sensor is manufactured and calibrated using the least-square calibration method. L2 relative error of the estimation of the radial force applied to the instrument tip is less than 6.30 %. The axial reaction force corresponding to the friction is also estimated with relative error less than 8.63 %.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130419816","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}
