Abstract:

The method presented in this paper is a new approach to solve the forward position problem in parallel manipulators. Mechanisms are modeled as a set of nodes related by geometrical constraints. These form a system of equations that is solved using an iterative process. The procedure is systematic and is integrated in a software package for the analysis and simulation of mechanisms. Its high computational efficiency gives it the potential to be implemented in a velocity control scheme.
