Cognitive robotics is a fascinating field in its own right and comprises both key features of autonomicity and cognitive skills like learning behavior. Cognitive architectures aim at mirroring human memory and assumptions about mental processes. A robot does not only extend the cognitive architecture regarding real-world interaction but brings new and important challenges regarding perception and action processes. Cognitive robotics is a step towards embodied cognition and may have influences not only on cognitive science but on robotics as well. This paper presents an integration of the cognitive architecture ACT-R on a simple but programmable robotic system. This system is evaluated on a navigation experiment.
