6DOF motion platforms are classified as parallel robotic devices for positioning and motion control. Consisting of two parallel plates and six adjustable legs, it allows precise adjustment and control of the plates, providing precise movement with high payloads. Initially, the equipment was used to test tires, and later, the 6dof platform began to be used in the medical industry, marine research, construction industry, space exploration, aerospace, automotive and machining industries.
The plate at the bottom of the 6DOF platform is the only static part of the device. The plate is preferably bolted to the floor or other surface. Its six legs connect the bottom plate to the moving top plate. To provide ample range of motion, different types of joints are used at each end of the outrigger. Usually each leg has a cylindrical housing, the length of each leg can be changed as needed, usually driven by a servo motor.
The main function of the shipboard stabilization platform is to provide a relatively stable working condition in the wave interference environment, and it is widely used in the fields of marine resource exploitation, shipboard weapon stabilization, satellite communication, and shipboard helicopter landing platform. The carrier-based stable platform has far-reaching significance for both economic development and military defense.
At present, the mainstream structure of the shipboard stabilized platform is still a series turntable based on gyroscopes, but the stabilized platform using this structure alone can compensate the disturbance of three degrees of freedom at most. The parallel mechanism based on the six-degree-of-freedom motion platform has six degrees of freedom in space, so using it as a stable platform can theoretically achieve full compensation for disturbances.
