Indoor SLAM using architectural plans
Get PDFPřesná lokalizace a mapování pomáhají robotům orientovat se v prostředí. V této práci je zkoumáno, jak může být kvalita simultánní lokalizace a mapování zlepšena architektonickými plány. Zvláštní pozornost je věnována vlivu integrace drobných chyb odometrie a environmentálních variací z architektonických plánů.Accurate localization and mapping help the robots to navigate in the environment. In this thesis, it is investigated how the quality of simultaneous localization and mapping can be improved by priors extracted from architectural plans. Particular attention is paid to the influence of integrating minor odometry errors and environmental variations from the architectural plans
Vision-guided handling operations for assistive robots in un-structured environments
Get PDFTeoretická cást práce se zabývá tématikou assistivních robotu ve zdravotnické a sociální péči a ilustruje možné aplikace pro mobilní manipulátory v dané oblasti. V praktické cásti zpracovává návrh asistivního robotu ve forme mobilního manipulátoru řízeného pomocí kamerou detekované sceny. Realizace je zjednodušená na pick and place task kamerou rozpoznaneho objektu pomocí manipulátoru Katana 400 vypracovaná v ROSu.The theoretical part of the thesis concentrates on the topic of assistive robots in health and social care and illustrates possible applications for mobile manipulators in the given area. In the practical part, it processes the proposal of an assistive robot in the form of a vision-guided mobile manipulator. The implementation is simplified on the pick and place task of a detected object by the camera using the Katana 400 manipulator written in ROS
Coordinated Motion Planning and Optimal Force Distribution for Robots with Multiple Cooperating Arms
Get PDFThis paper is concerned with the problems of inter-arm coordination which arise when multiple robot arms attach their end effectors to a single payload in order to perform a manipulation task. The approach taken is to let the arms cooperate with equal rights, and to exploit the redundancy present in the system for the minimization of a quadratic cost criterion. The main elements of the proposed control system are generators for coordinated nominal motions and force/torque interactions with the payload, and an active compliance scheme capable of resolving kinematic conflicts and inconsistencies between motion and force/torque commands. The paper gives a detailed mathematical description of both the motion and the force/torque generators. The proposed active compliance scheme is presented in summary form

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
