      This paper considers a grasp planning scheme for dextrous hands. The grasp is assumed to be a preciseone, which means that only the fingertips of the hand are in contact. The most important algorithm ofthe grasp planner ...
    • Modelling of Computer Integrated Transportation 

      Csiszár, Csaba; Westsik, György (Budapest University of Technology and Economics, 1999)
      The modern control of physical processes of transportation requires the development and then the integration of computer aided functional subsystems. In this integrated system a database working as a network centre has to ...
    • Intelligent stereo vision system for robotic applications 

      Tél, Ferenc; Lantos, Béla (Budapest University of Technology and Economics, 1999)
      This paper describes an intelligent vision method, which is capable of reconstructing the robot environment. Algorithms and their implementation are presented for localising known objects in the scene and determine 3D ...
    • Improved stratified control for hexapod robots and object manipulation with finger relocation 

      Harmati, István; Lantos, Béla; Shahram Payandeh (Budapest University of Technology and Economics, 1999)
      The paper deals with the motion design of legged robots and dextrous hands. We show the possibilities and limitation of conventional stratified control approach through the relative simple example of hexapod robot and offer ...
    • Numerical modelling of the mechanical process of particle detachment by finite element method 

      Eleőd, András; Devecz, János; Balogh T (Budapest University of Technology and Economics, 2000)
      This paper presents a numerical simulation technique for calculating the strain and the stress state at every point of the surfaces, containing real surface topology and layered structure. Depending on the nature of ...
    • Gas Dynamic Pipe Flow Effects in Controlled Pneumatic Systems - A Simulation Study 

      Szente, Viktor; Hős, Csaba János; Istók, Balázs; Vad, János; Kristóf, Gergely (Budapest University of Technology and Economics, 2001)
      Electro-pneumatic modulators (EPMs) are widely used in controlled pneumatic systems. Their aim isto ensure a controlled operating pressure modulated at a high accuracy and high temporal resolution.This paper reports a ...
    • Competing Through New Product Development Supported by Knowledge Gained from Investigations on Success Factors. 

      Vágási, Mária (Budapest University of Technology and Economics, 2002)
      The paper discusses the management application of revealed and/or benchmarked success factors of new product development. It couples success factors and recent management concepts on competitiveness. Information related ...
    • A nonlinear observer for flexible joint robots 

      Gyurkovics, Éva; Svirko D (Budapest University of Technology and Economics, 2002)
      This paper presents the design of a kind of semiglobal nonlinear observers for flexible joint robots which needs the measurements of the positions of each motor rotor and link. For the proposed observer, the error equation ...
