Machines for hazardous and distant environments
Robots extend human reach into places that are dangerous, remote, or too expensive for direct human work. Space robotics includes planetary rovers, robotic arms, autonomous landers, inspection craft, and laboratory systems that handle repetitive experiments.
Mobility and manipulation
A rover must estimate its position, choose safe routes, manage wheel slip, and operate instruments despite dust and uneven terrain. Robotic arms require accurate sensing, careful force control, and mechanisms designed for thermal cycling and long periods without maintenance.
Autonomy and teamwork
Autonomous robots can combine cameras, lidar, inertial sensors, and maps to make local decisions. Teams of smaller robots could survey a wide area, but coordination, communication loss, energy limits, and fault recovery remain difficult research problems.
Evaluation
Editorial standard: distinguish established observations from active research and future concepts; check primary scientific sources for current evidence.
