A laminate linkage with soft actuation includes a plurality of rigid plates joined at flexible joints; at least one balloon bonded to at least one of the rigid plates and configured to generate a displacement (extension, a change of yaw, and/or a change of pitch) of at least one of the rigid plates; and a fluid source in fluid communication with an interior volume of the balloon and configured to pump fluid into the balloon to generate the displacement of at least one of the rigid plates.

Soft actuators for pop-up laminate structures

Systems and methods for fabricating 3D soft microstructures. The system comprises injecting a pressurized, curable liquid into certain structural layers induces folding and allows the 2D structures to reconfigure into a 3D form In addition to the injection of a curable liquid that permanently reconfigures the structure of the system, in an embodiment this method also allows for the injection of other liquids into certain actuator layers that enable motion in certain portions of the system Furthermore, the system allows for handling of colored fluids that are passed to visualization layers. The method of creating such a system depends on taking advantage of laser machining of the individual layers to influence the behavior of how different portions bend and move.
