This period also saw the emergence of teleoperation, where astronauts could control robotic systems remotely from the station. As technology progressed, researchers and engineers began focusing on developing more autonomous capabilities for robots, paving the way for enhanced human-robot interaction in subsequent space missions.

Theoretical Foundations

Human-robot interaction in autonomous space missions is grounded in several theoretical frameworks that address human factors, robotics, and system design. One of the primary theories is the social-robot interaction model, which emphasizes the significance of social cues and communicative behaviors between humans and robots. This model posits that successful interactions depend on the robot's ability to interpret and respond to human signals effectively.

Another important theoretical perspective is human-centered design, which advocates for designing robotic systems that prioritize user needs and usability. This approach involves iterative testing and feedback processes to ensure that the robotic systems are intuitive and accessible for human operators, especially given the unique stressors and challenges of space environments.

Moreover, cognitive models of interaction inform the design of autonomous systems by predicting how humans will interact with robots in various scenarios. These models incorporate aspects of human cognition, such as decision-making and situational awareness, which are critical for maintaining effective communication and ensuring mission success in unpredictable circumstances.

Key Concepts and Methodologies
