| description | The purpose of this research is to suggest tendon placement generation rules for folding transformation into multiple shapes. As a method to propose how to generate tendon placement, a method combining trial production, geometric interpretation, and algorithm development was used. Firstly, trial production and its analysis were carried out. As a result, it was found to be possible to drive consecutive folding operations and to drive the folding transformation into multiple shapes from the same panel by using the method that the tendon was penetrated the overlapping of plates in the shape after the folding transformation. And the rule that tendon placement can be generated by repeating primary transformation of starting point of tendon placement was extracted. Secondly, tendon placement generation algorithm based on the tendon placement generation rules, and state transition diagram generation algorithm were developed. Thirdly, experimenting the motion of the panels with tendon placement generated by the algorithm mounted, the operation of the algorithm was confirmed and the behavior of the panels was investigated. Finally, by examining the experimental results, the effective range of the algorithm was found to be folding transformation composed of up to two folding operations. From this, it was found that the applicable range of the extracted rules were folding transformation composed of up to two folding operations. By referring trial tendon placement generated for folding transformation composed of three folding operations, rules were modified. Therefore, it turned out that driving of the origami panel using the discovered tendon placement was realized by the mechanism of bringing all overlapping points closer by pulling the tendon, and the extracted rules were found to be effective for realizing driving of folding transformation from the same panel into multiple shapes. |
