This technical seminar covers behavior-based robotics and its applications. It begins with definitions of robots, robotics, and behavior-based robotics. It describes how behavior is expressed through stimulus-response diagrams and finite state machines. Behavior-based architectures like subsumption architecture and motor schemas are explained. The history of robotics is reviewed from mechanical robots to present-day humanoids. Applications include entertainment, exploration, medical assistants, transportation, and more. Key issues discussed are grounding in reality, situatedness, embodiment, emergent behavior, and scalability.
