Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 116)


In this chapter we present a self-valuing learning system based on continuous B-spline model which is capable of learning how to grasp unfamiliar objects and generalize the learned abilities. The learning system consists of two learners which distinguish between local and global grasping criteria. The local criteria are not object specific while the global criteria cover physical properties of each object. The system is self-valuing, i.e. rates its actions by evaluating sensory information and the use of image processing techniques. An experimental setup consisting of a PUMA-260 manipulator, equipped with hand-camera and force/torque sensor, was used to test this scheme. The system has shown the ability to grasp a wide range of objects and to apply previously learned knowledge to new objects.
