Abstract Developable mechanisms conform to and emerge from developable, or specially curved, surfaces. The cylindrical developable mechanism can have applications in many industries due to the popularity of cylindrical or tube-based devices. Laparoscopic surgical devices in particular are widely composed of instruments attached at the proximal end of a cylindrical shaft. In this paper, properties of cylindrical developable mechanisms are discussed, including their behaviors, characteristics, and potential functions. One method for designing cylindrical developable mechanisms is discussed. Two example developable surgical devices that exemplify these behaviors, characteristics, and functions, along with the kinematic mechanisms comprising them, are discussed in detail.

Abstract The potential of compliant mechanisms and related origami-based mechanical systems to store strain energy make them ideal candidates for applications requiring an actuation or deployment process, such as space system arrays, minimally invasive surgical devices and deployable barriers. Many origami structures can be thought of as a compliant mechanism because, like compliant mechanisms, its function is performed through the elastic deformation of its members. This stored strain energy could prove useful. There are opportunities using strain energy to develop approaches to deploy particular mechanical systems. In order to better understand the principles of self-actuation and promote the designs of such systems, a taxonomy of deployable origami mechanisms is presented. This taxonomy demonstrates that there are several different types of deployable origami mechanisms and provides an organizational method to better understand the design space. Characteristics of self deployment in concentrated, deployable origami strain energy mechanisms with internal actuation are identified and examples of strain energy based deployment are provided.
