This paper reports the preliminary results of a research effort aiming at conceptualizing novel insect/machine hybrid controllers for autonomous exploratory vehicles. In particular, we investigate the possibility to include pre-developed animal intelligence capable of sensory-motor integration, decision-making and learning behaviors. In this context we present an in-depth review of insect neurophysiology focussing on mechanisms related to navigation. In addition we critically review current approaches towards hybridity and insect/machine interfaces. Finally, a novel insect/machine hybrid control architecture is proposed. It includes biological/artificial modules and deliberative/reactive behaviors.
