Abstract-This paper proposes an architecture for tactile-based fabric learning and classification. The architecture is based on a number of SVM-based learning units, which we call fabric classification cores, specifically trained to discriminate between two fabrics. Each core is based on a specific subset of the fully available set of features, on the basis of their discriminative value, determined using the p-value. During fabric recognition, each core casts a vote. The architecture collects votes and provides an overall classification result. We tested seventeen different fabrics, and the result showed that classification errors are negligible.

The paper discusses the development of the dynamic model and the design of the control system of a new parallel robot called PmarNeedle. The PmarNeedle was purposely designed for needle surgery, one of the current frontiers of minimally invasive surgery, as slave robot driving the surgical tool within a surgical theater whose dimensions are small compared to in use robotic surgery theaters for laparoscopy. The paper presents the PmarNeedle kinematic and dynamic model used to define the control laws and to setup the control parameters. Simple PD control laws with and without non-linearities compensation filters have been implemented. The work is developed in ProEngineer, Simulink and SimMechanics. Results obtained in the simulation environment are discussed

Summary. This paper describes the development of a five degree of freedom towed underwater vehicle designed for condition monitoring of undersea pipelines. Its innovative design, with 6 fins actuated by 5 motors adding heave and sway capabilities to the yaw, roll and pitch movements possible in traditional designs, is explained. The parameters influencing the stability and the design in general are analyzed. A Control strategy for this design of highly coupled movements and control modes encompassing all the operational scenarios, are presented.
