Modelo de Denavit Hartenberg Num trabalho pioneiro, que at6 hoje serve de referncia para a pesquisa de estmturas articuladas, Denavit e Hartenberg [DEN 55] descreveram relacionamentos translacionais e rotacionais entre pe9as articuladas adjacentes para manipuladores mecfinicos. Eles usaram um m6todo matricial, que estabelece um sistema de coordenadas para cada junta da estmtura. Matrizes de transformagio entre esses sistemas de coordenadas so ....

....which implies the lack of an ultimate formal design objective. IV. MANIPULATOR KINEMATICS In this chapter we describe the development of a closedform solution of the manipulator s inverse kinematics problem. First, the forward kinematics parameterization using Denavit Hartenberg convention [3] is given in chapter IV A. The result will be used in chapter IV B in which our algorithm for the solution of the inverse kinematics problem is explained. Finally chapter IV C deals with the optimization method employed, using the redundancy of the manipulator to increase the systems performance ....
....Finally chapter IV C deals with the optimization method employed, using the redundancy of the manipulator to increase the systems performance in terms of manipulability. A. Forward Kinematics We describe the forward kinematics of the manipula tor in terms of Denavit Hartenberg notation [3] because of the portability of this method which is well known both in the academic and in the industrial field. The Denavit Hartenberg parameterization of the manipulator is shown in Table I. joint bi ci ai di type [dg] dg] mm] mm] I 90 90 175 185 prismatic 4 90 90 0 160 revolute ....

....kinematics TBH (q) Note that these frames can be chosen arbitrarily, so long as they are rigidly linked to the tip or the base. A common choice however is to allocate such frames according to the Denavit Hartenberg conventions. Denavit Hartenberg kinematic model The DH conventions [16] are a standard method for almost uniquely allocating frames on the elements of the chain, that allow the linkages to be parameterized minimally. This is done such that the geometry of the j element is represented by a link transform L j and a joint transform J j . The so called ....

....convenient to consider A [ as a graph in which the joints correspond to vertices and the links correspond to edges. Therefore, let GM denote the underlying graph of A I. Now consider the kinematics of A [ Using a standard parameterization technique, such as the Denavit Hartenburg representation [13, 15], the configuration of A [ can be expressed as a vector, q, of real valued parameters. Let denote the configuration space or C space. Let A g(q) denote the transformation of A [ to the configuration given by q. Note that the graph GM is a tree if and only if there are no closed kinematic chains. ....

....magnetic fields. However, these approaches will not be considered here. A display s kinematic parameters describe the interrelation between the displays s various degrees of freedom (DOF) or joints. A commonly used convention for these parameters is called the Denavit Hartenberg (DH) notation [22][28]. With the coordinate frames that come with the DH notation, the four parameters for each DOF can be represented by a homogeneous transform matrix, between a given DOF and the next DOF in the kinematic chain. Thus the 44 kinematic structure of a DOF mechanism can be summarized by a series of ....

Constructing the Joint Coordinate Systems A kinematic model can be represented using the Denavit Hartenberg (DH) method [11 ] by defining the position and orientation of two consecutive links in a chain, link i with respect to link i l, using a 4x4 homogeneous transformation matrix Fi as shown below. cos0 i sin0 icosa i sin0 isina i a icos0 i sii0i cs0icsai cos0isina i aisinO i F = sinai csai di 0 0 1 for i = ....

....consecutive sweeps of an object. The Lie group of Euclidean motions is 6 D (6 parameters) and the swept volume of a 3 D object can usually be expressed in terms of 4 parameters. Therefore, the potential for SEDE method to address consecutive sweeping exists. The Denavit Hartenberg (DH) method [22 24] was created to systematically establish a coordinate system in each link of an articulated kinematic chain. A mechanism, composed of several links can be represented using the DH method to relate the position and orientation of the last link to the first. Because of the DH method, displacement ....
