AR support system for constructing tensegrity structures


Tensegrity structures are created using isolated struts held together with cables. By utilizing the tensile strength of the cables to place a compressive force on the struts, the structures feature high structural integrity and mechanical stability.

This is an AR support system for constructing objects with a tensegrity structure, created by the Hirasawa Lab at Chiba University.

"We liked this shape a lot. But things like this are difficult to design and build. So, we're using AR to support their construction."

"This structure consists of three-rod units. Here, we're using AR to help fabricate the units correctly."

"As you can see, the ends of these rods have red target marks on them. The marks are there to show whether the top is in the right position. I think you can see that this one is misaligned, but if we line it up, a different part gets out of alignment. In ways like this, tensegrity units involve a delicate balance of wire tensions. So, it's difficult to adjust their positions overall. If you pull this, then these match, but this one goes too far. It's really hard to adjust them while measuring them in the same way. So, the method we suggest is to build the structure while checking that the overall concept is correct, using AR to help."

"Currently, many of these objects are used as art installations. But we're doing research with the aim of utilizing such structures in architecture."

"For example, if this kind of tensegrity structure is used for the roofs of temporary booths, we think that would be really attractive. As a dream project, we think it would look great if pavilions and stadiums at the Tokyo Olympics had these roofs."
