The Ubichip is a reconfigurable digital circuit with special bio-inspired mechanisms that supports dynamic partial reconfigurability in a flexible and efficient way. This paper presents an adaptive size neural network model with incremental learning that exploits these capabilities by creating new neurons and connections whenever it is needed and by destroying them when they are not used during some time. This neural network, composed of a perception layer and an action layer, is validated on a robot simulator, where neurons are created under the presence of new perceptions. Furthermore, links between perceptions and actions are created, reinforced, and destroyed following a Hebbian approach. In this way, the neural controller creates a model of its specific environment, and learns how to behave in it. The neural controller is also able to adapt to a new environment by forgetting previously unused knowledge, freeing thus hardware resources. We present some results about the neural controller and how it manages to characterize some specific environments by exploiting the dynamic hardware topology support offered by the ubichip.
