A Better Way to Construct Tensegrities: Planar Embeddings Inform Tensegrity Assembly
نویسنده
چکیده
Although seemingly simple, tensegrity structures are complex in nature which makes them both ideal for use in robotics and difficult to construct. We work to develop a protocol for constructing tensegrities more easily. We consider attaching a tensegrity’s springs to the appropriate locations on some planar arrangement of attached struts. Once all of the elements of the structure are connected, we release the struts and allow the tensegrity to find its equilibrium position. This will allow for more rapid tensegrity construction. We develop a black-box that given some tensegrity returns a flat-pack, or the information needed to perform this physical construction.

Automated discovery and optimization of large irregular tensegrity structures
Tensegrities consist of disjoint struts connected by tensile strings which maintain shape due to pre-stress stability. Because of their rigidity, foldability and deployability, tensegrities are becoming increasingly popular in engineering. Unfortunately few effective analytical methods for discovering tensegrity geometries exist. We introduce an evolutionary algorithm which produces large tense...
متن کاملA Transformation Groups Point of View on Connelly’s Global Rigidity Theorem for Free Equivariant Tensegrities
In the mid 1990’s, one of the authors [C4] generalized earlier work with Maria Terrell [CT] to prove a remarkable result on the global rigidity of certain symmetric tensegrities. Global rigidity is a statement of transitivity for the action of the Euclidean motions on a certain sets of tensegrities. The purpose of this paper is to present a transformation groups and representation theoretic poi...
متن کاملDYNAMIC RELAXATION OF TENSEGRITY STRUCTURES 553 DYNAMIC RELAXATION OF TENSEGRITY STRUCTURES A Computational Approach to Form Finding of Double-layer Tensegrity Grids
The structural hierarchy inherent to tensegrities enables a building skin that performs on multiple levels simultaneously. While having one function in the global building mechanics, its individual components can work as self-contained systems balancing tensile and compressive forces locally within them. The behavior of elements under load is linear and thus describable analytically. When these...
متن کاملTensegrities and Global Rigidity
A tensegrity is finite configuration of points in Ed suspended rigidly by inextendable cables and incompressable struts. Here it is explained how a stress-energy function, given by a symmetric stress matrix, can be used to create tensegrities that are globally rigid in the sense that the only configurations that satisfy the cable and strut constraints are congruent copies.

Tensegrity structures are spatial, reticulate and lightweight systems composed of struts and cables. Stability is provided by the self-stress state between tensioned and compressed elements. Tensegrities have received interest among scientists and engineers in fields such as architecture, civil and aerospace engineering. Flexibility and ease of tuning make these innovative systems attractive fo...
