Nonlinear Control of Constrained Redundant Manipulatorsd a still nonlinear dynamics in the subspace of the redundant degrees of freedom. By projecting artificial potential and damping forces into the subspace of the redundant degrees of freedom, it is possible e. g. to realize repeatable motions in the joint space for cyclic trajectories or to avoid collisions with obstacles in the workspace.

The Kinematics of 3-DOF Planar and Spherical Double-Triangular Parallel Manipulatorshe spherical mechanism. Numerical examples are included that admit two real solutions for the former and four real solutions for the latter, among which only two positive values are acceptable. All solutions, both real and complex, are listed.

Einleitung: Vom sichtbaren Unsichtbaren,ution of a generalized eigenproblem .·ρ+λ .·ρ=.. Related single-loop mechanisms can also be solved. The eigenproblem-method is numerically stable, because eigensystems can be computed without previous determination of the characteristic polynomial. Furthermore, a compact and efficient formulation of

Elementary problems concerning the special case tan(±π/2) and the introduction of trivial extraneous roots into systems of equations are well known and can be handled. The artic

The validity of these methods is questioned from the viewpoint of the computational efficiency specified in terms of arithmetic operations per iteration step. Even though the pseudo-inverse-based methods provide better convergence, less computation time is needed by steepest descent methods

Strukturbildende Psychotherapieity .. This set can be described by means of the fasible ranges of values that each variable can take. It is possible, for all planar and spherical loops, obtaining such ranges without explicitly finding the algebraic expression of the solution. The form presented by such ranges permits inferring to
