Motion platform having decoupled two axes

摘要

A motion platform having decoupled two axes adopts four modularized pneumatic bellows configured in an orthogonal arrangement. The pneumatic bellows can be independently controlled to cause the motion platform to be operated in one rotational degree of freedom with a frontward-and-backward swinging or a leftward-and-rightward swinging; or the pneumatic bellows can be synchronously controlled to cause the motion platform operated in two rotational degrees of freedom without being interfered with each other. Thus, the motion platform of the present disclosure is characterized with advantages of simplified mechanism, fewer components, convenient maintenance and reduced cost.

1. A motion platform having decoupled two axes, comprising:
a base chassis configured for being disposed on a ground base; a movable frame; and four first pneumatically-driven elements securely sandwiched between the base chassis and the movable frame, and each of the four first pneumatically-driven elements is respectively located at a middle of each side of a top surface of the base chassis, and one imagined linear line linking two of the first pneumatically-driven elements is orthogonal to another imagined linear line linking the other two of the first pneumatically-driven elements such that the movable frame is capable of rotating in two rotational degrees of freedom.
