  2. Reactive Behaviour and Deliberative Reasoning in a Hybrid Architecture for Autonomous Robot. Project Goal Developing a software for simulation of the autonomous approach and docking for multy agent robots composed by multy chaser spacecraft to a target spacecraft simulator floating via air pads on a flat door. Spacecraft Robotics Laboratory Alessandro Allegro @ Oct 2006

  3. Reactive Behaviour and Deliberative Reasoning in a Hybrid Architecture for Autonomous Robot. Introduction The humans are a sophisticated ‘autonomous agents’, and they are able to realize reactive and deliberative actions. Reactive actions are fast, instinctive responses that take place in response to dangerous conditions or engender fear. This kind of reaction has the principle function of defense from unexpected or dangerous events. Deliberative Action, on the other hand, are those actions that take place after logical reasoning. This kind of actions are slowly than reactive actions, but they are more accurate and complex than reactive actions. Spacecraft Robotics Laboratory Alessandro Allegro @ Oct 2006
