On the dynamics of active categorisation of different objects shape through tactile sensors

Active perception refers to a theoretical approach to the study of perception grounded on the idea that perceiving is a way of acting, rather than a process whereby the brain constructs an internal representation of the world. In this paper, we complement previous studies by illustrating the operational principles of an active categorisation process in which a neuro-controlled anthropomorphic robotic arm, equipped with coarse-grained tactile sensors, is required to perceptually categorise spherical and ellipsoid objects.
