A six-degree-of-freedom travelling system, wherein a solid is driven by eight suspending lines in six degrees of freedom. The six-degree-of-freedom travelling system can be provided as a bodily sensing machine comprising a human-riding cage: eight suspending lines in connection with the cage; eight actuators hauling and veering the respective lines for vary the position and attitude of the cage, and a controller controlling the eight actuators for constantly holding the eight lines under proper tensions, wherein the cage is travelled in six degrees of freedom.

6-degree-of-freedom travelling system

A method of determining the success or failure of the press fitting a workpiece into an object member having a contact end by a linearly-driven plunger is disclosed. In a predetermined stroke range RM of the plunger press fitting the workpiece, thrust information S1 and position information S2 are acquired. The position where the ratio of change of the thrust information S1 with respect to the position information S2 exceeds a predetermined value is detected as an almost press fit end position LLP. The success or failure of the press fitting work is determined according to whether the thrust information S1 is included in a predetermined range of a section from a predetermined determination start position LLH to a determination end position LLQ during the press fitting work. The determination end position LLQ is determined based on the almost press fit end position LLP. The press fitting force is determined at a position nearest to the contact end, thereby making it possible to determine the success or failure of the press fitting work accurately.
