Abstract
A floating board is installed on a surface table through an extremely low friction plane sliding and supporting mechanism, such as using a gas bearing, of two-dimensional 3 freedom to thereby constitute a plane sliding mechanism portion, and a vertical sliding shaft tube supported to be enable translation in a vertical direction and connected to a balance belt for applying a balance weight is provided on the floating board through an extremely low friction vertical shaft sliding and supporting mechanism, such as a bas bearing, to thereby constitute a vertical shaft sliding mechanism portion. Further, a spherical shaft is installed above the vertical sliding shaft tube of the vertical shaft sliding mechanism portion through an extremely low friction 3-freedom rotational and supporting mechanism, such as using a gas bearing, to thereby constitute a 3-axis turning rotational mechanism portion, and a specimen model loading portion is provided on the spherical shaft to thereby obtain a three-dimensional free motion apparatus that can be applied to an agravic environment simulation experimental apparatus, an evaluation and test apparatus for a flexible-article handling work robot, and the like, in which as a whole, the 3-axis translation and the motion function of 3-axis turning 6-freedom can be secured in the extremely low friction state.
