Pneumatic driven robots possess high-efficiency, safe-operation and fast response features, which have been widely used in our daily lives, such as pneumatic driven bus doors. Soft pneumatic robots as one specific type are inherently advantageous since they are soft, lightweight, easy to process and low cost. The Mckibben robot (MR) is a well-known cylindrical pneumatic soft robot, which consists of a cylindrical elastomeric bladder wrapped by a braided sleeve. The outside braided sleeve is a very critical part since it has a unique structure that shortens while expands in the
circumference. Unlike most other soft robots that expand upon stimulation, MRs can contract in longitudinal direction and expand in radial direction while inflating. These robotic movements are rather similar to those generated by humans or other vertebrates’ muscles. In the past decades, MRs have been recognized to have the potential to be miniaturized into the fiber shape that can be further be integrated into fabrics for compliant and wearable devices. In this research, four tasks will be taken on. The four tasks are defining superfine elastomer’s bladder properties, defining desired braiding yarn properties, designing a braided sleeve around the inflatable bladder to fabricate fiber-based MRs, and characterizing the produced fiber-based MRs and establishing a design portfolio.
