چکیده

Articolul stabileşte relaţii matriceale pentru cinematica şi dinamica robotului paralel Orthoglide prevăzut cu trei acţionori prismatici concurenţi. Aceştia sunt aranjaţi în raport cu sistemul cartezian de coordonate astfel încât direcţiile lor să fie normale unele faţă de celelalte. Trei lanţuri cinematice identice, conectate la platforma mobilă, sunt localizate în trei plane perpendiculare unul pe celălalt. Cunoscând poziţia şi mişcarea de translaţie a platformei, se dezvoltă problema de cinematică inversă şi se determină poziţia, viteza şi acceleraţia fiecărui element al robotului. În continuare, principiul lucrului mecanic virtual este folosit în problema de dinamică inversă. Câteva ecuaţii matriceale oferă expresii recurente şi grafice pentru forţele active şi puterile mecanice ale celor trei acţionori.

Using the Matrix Method to Compute the Degrees of Freedom of Mechanisms

In this paper, some definitions and traditional formulas for calculating the mobility of mechanisms are represented, e.g. Grubler formula, Somov - Malyshev formula, and Buchsbaum - Freudenstei. It is discussed that there are certain cases in which they are too ambiguous and incorrect to use. However, a matrix method is suggested based on the rank of the Jacobian of the mechanism and its applica...

Mechanical System Modelling of Robot Dynamics Using a Mass/Pulley Model

The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...

Kinematic and Dynamic Analysis of the 2-DOF Spherical Wrist of Orthoglide 5-axis

This paper deals with the kinematics and dynamics of a two degree of freedom spherical manipulator, the wrist of Orthoglide 5-axis. The latter is a parallel kinematics machine composed of two manipulators: i) the Orthoglide 3-axis; a three-dof translational parallel manipulator that belongs to the family of Delta robots, and ii) the Agile eye; a two-dof parallel spherical wrist. The geometric a...

Kinematic Analysis and Trajectory Planning of the Orthoglide 5-axis

The subject of this paper is about the kinematic analysis and the trajectory planning of the Orthoglide 5-axis. The Orthoglide 5-axis a five degrees of freedom parallel kinematic machine developed at IRCCyN and is made up of a hybrid architecture, namely, a three degrees of freedom translational parallel manipulator mounted in series with a two degrees of freedom parallel spherical wrist. The s...
