Abstract

There is provided a tensegrity design system and a method for use in designing a complex tensegrity structure. In one implementation, such a method includes providing virtual building blocks selectable by a user for assembly of a desired tensegrity structure, receive user-selected building blocks from among the plurality of virtual building blocks from the user, and identifying connections among the user-selected building blocks based on user inputs to the tensegrity design system. The method also includes determining a network of forces for stabilizing a tensegrity structure corresponding to the desired tensegrity structure, based on the user-selected building blocks and their connections, and generating a simulation of the tensegrity structure corresponding to the desired tensegrity structure for display to the user.
