Biomechanics of the slingshot spider and its three-dimensional web

South African Journal of Science
A three-dimensional model for the release dynamics of a category of orb web spiders is developed. The web response depends on the material properties of the web silk and its geometric layout.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
