In this work, a novel approach that uses 2D data and simple image processing techniques is introduced. A unique image vector descriptor (CFD&POSE) containing also depth information is computed and then input to a Fuzzy ART MAP architecture for learning and recognition

However, the uncertainties involved during assembly make it difficult to conceive such a model. In these cases, the use of a connectionist model can be advantageous. In this paper the design of a neural network controller (NNC) based on unsupervised learning is presented. The NNC consists

The main objective is to integrate all devices needed to perform the simulation using Delmia V5 Robotics and to avoid any possible mistake when implementing of the real workcell; for example, with physical dimensions, possible collisions, path planning, etc. The feasibility in the implementation can be determined trough 3D simulation of a manufacturing workcell to perform tasks type MIG welding. * Doctoral Student programme PICyT with terminal option Eng.
