In recent years, parallel intelligent robots have been a key research focus in robotics. As a classic example of parallel robotic systems, the Stewart platform attracts significant attention from researchers. This paper first analyzes the structural features of the Stewart platform, detailing its actuation methods, kinematic configurations, and control objectives. It then introduces the platform’s applications in various fields: flight, driving, and marine simulators; precision machining and assembly; and positioning systems for satellite antennas and telescopes. The discussion also covers the Stewart platform’s roles in suppressing micro-vibrations in spacecraft, mitigating multi dimensional vibrations in vehicles, and enabling vibration testing and simulation. Finally, the paper summarizes current advancements and outlines future development directions, highlighting emerging trends in both theoretical research and engineering applications.
