HBBA - Hybrid Behavior-Based Architecture
Our new Hybrid Behavior-Based Architecture (HBBA) combines our latest research in autonomous mobile robots control architectures and is the logical evolution of our Motivational-Behavioral Architecture (MBA, [cite!]). It currently powers the mind of our humanoid robot, Johnny 0.
Our decisional structure remains heavily distributed. Motivation modules provides the system with high-level desires. The Intention Workspace acts as a blackboard - a sharing space for motivation modules to post their desires. The Intention Translator takes these desires and translate it into a tangible intention for the controlled robot. This means our motivation modules are loosely coupled with the actual robot, making them portable between different instances of our architecture. Selective attention mechanisms implemented within the translator try to make the most of our platforms' limited ressources by activating competing perceptual and behavioral strategies in line with the current situation. The Egosphere surveys perceptual events and builds a more manageable abstraction of every sensorial inputs provided by our hardware. The Emotional Subsystem regulates desires' intensities according to the simulated mood of the robot, which varies in relation to the current intention accomplishment.
