Abstract

The sequential actuation control, or folding in the case of origami-inspired mechanisms, is an essential feature to achieve more complex geometries avoiding a self-collision between parts during assembly. It also allows motion programming in its structure and material. Electronic controllers and smart materials can be employed in this case allowing autonomous action and, in the case of smart materials, passive energy. However, adopting a more structure-focused approach can reduce the complexity and number of responsive actuators and even eliminate the need for active drivers, which is especially useful in extreme environments where electronics can be affected, for example, cosmic radiation in space. This work focuses on a structural approach to generate an actuation sequence in origami-inspired mechanisms applying bend patterns that exhibit multi-stability features.(AU)
