Tom Masselter and his co-authors describe the development of a 3D reticuated actuator inspired by the up-righting movement through a cortical fiber network found in the biological models balsa, papaya and the fossil seed fern Lyginopteris oldhamia. In the freely available publication, they provide background information on the movement principle, building instructions and hands-on experiments suitable for teaching.
