Soft Pneumatic Actuators for Soft Robotics: A Motion-Based Review of Actuation Mechanisms and Performance Trade-offs

The paper frames the work as controlControl & PlanningControlThe method used to make the robot move the way you want.. Start here because it defines what success means and which assumptions the rest of the method inherits.

This comprehensive review categorizes soft pneumatic actuators by their motion patterns (linear, bending, twisting, omnidirectional) and explains how design choices like braid angle, chamber geometry, and fiber orientation directly impact force output, air efficiency, and durability.
