In essence, the six-degree-of-freedom Stewart platform is designed based on the six degrees of freedom of an object in space. An object in space has six degrees of freedom, namely the translational degrees of freedom along the three rectangular coordinate axes x, y, and z, and the rotational degrees of freedom about these three coordinate axes.

The six-degree-of-freedom Stewart platform is typically composed of six electric cylinders, six universal hinges on both the upper and lower parts, and two platforms, an upper platform and a lower platform. The lower platform is fixed to the foundation. By means of the telescopic motion of the six actuating cylinders, the upper platform can complete the motion of six degrees of freedom (X, Y, Z, α, β, γ) in space, thereby simulating various spatial motion postures. Simply put, the six-degree-of-freedom Stewart platform is like a magical stage that can "dance" in all directions in a three-dimensional space.

In the aerospace field, the six-degree-of-freedom Stewart platform plays an irreplaceable role.

For example, in flight simulators, the six-degree-of-freedom Stewart platform can simulate various complex postures of an aircraft during flight, including takeoff, cruising, landing, the up-and-down undulations and left-and-right swaying when encountering air turbulence, as well as the pitch and yaw of the fuselage and other states.

By conducting a large number of trainings on the simulator based on the six-degree-of-freedom Stewart platform, pilots can accumulate rich flight experience in a safe environment, get familiar with the operation and response in various flight situations, and greatly improve the safety during actual flight and the ability to deal with emergencies.

At the same time, in the research on spacecraft docking, the six-degree-of-freedom Stewart platform can also simulate the relative motion of spacecraft in the space environment, helping researchers to better conduct the research and development and experiments of docking technology.

In the entertainment industry, the six-degree-of-freedom Stewart platform has brought an unprecedented immersive experience to audiences and players.

Dynamic movies are one of its common application scenarios. When the audience sits on the special seats based on the six-degree-of-freedom Stewart platform to watch a movie, the platform will make corresponding movements in real time according to the plot in the film, such as the speeding of a vehicle, the dive of an aircraft, the vibration of an earthquake, etc., making the audience feel as if they are on the scene, greatly enhancing the viewing and entertainment value of the movie.

In the amusement facilities of large theme parks, the six-degree-of-freedom Stewart platform also shows its great capabilities. Some devices simulating thrilling projects such as roller coasters and interstellar travel can achieve rapid lifting, rotation, tilting and other movements through the six-degree-of-freedom Stewart platform, bringing visitors a thrilling playing experience.
