Abstract
The present invention relates to a pneumatic structure () comprising an inextensible body () defining at least a network of internal cavities (), each cavity having a closed contour in at least one section of the cavity Each cavity being suitable for being pressurized so as to change the inextensible body from a rest configuration to at least one pressurized configuration, Inextensible body having, in each pressurized configuration, a macroscopic metric different from its macroscopic metric in the rest configuration, Each cavity being formed of at least two substantially rectilinear channels, each channel being fluidly connected to at least one of the other channels, the two said channels forming a heading change angle, Each cavity comprising at least one non-zero heading change angle, in particular at least three non-zero heading change angles.
