Abstract-- A tensegrity-based system is a promising approach for dynamic exploration of uneven and unpredictable environments, particularly, space exploration. However, implementing such systems presents challenges in terms of intelligent aspects: state recognition, wireless monitoring, human interaction, and smart analyzing and advising function. Here, we introduce a 6-strut tensegrity integrate with 24 multimodal strain sensors by leveraging both deep learning model and large language models to realize smart tensegrity. Using conductive flexible tendons assisted by long short-term memory model, the tensegrity achieves the self-shape reconstruction without extern sensors. Finally, human interaction system of the tensegrity helps human obtain necessary information of tensegrity from the aspect of human language. The concept of using tensegrity structures in space exploration is an innovative approach that offers several advantages due to the unique properties of tensegrity systems. One famous example is the "Super Ball Bot" developed by NASA (National Aeronautics and Space Administration) [1][2]. Tensegrity structures are composed of solid compression components (rods/struts) connected by tension elements (cables/strings).

Design and control of a collision-resilient aerial vehicle with an icosahedron tensegrity structure
Zha, Jiaming, Wu, Xiangyu, Dimick, Ryan, Mueller, Mark W.
We introduce collision-resilient aerial vehicles with icosahedron tensegrity structures, capable of surviving high-speed impacts and resuming operations post-collision. We present a model-based design approach, which guides the selection of the tensegrity components by predicting structural stresses through a dynamics simulation. Furthermore, we develop an autonomous re-orientation controller that facilitates post-collision flight resumption. The controller enables the vehicles to rotate from an arbitrary orientation on the ground for takeoff. With collision resilience and re-orientation ability, the tensegrity aerial vehicles can operate in cluttered environments without complex collision-avoidance strategies. These capabilities are validated by a test of an experimental vehicle operating autonomously in a previously-unknown forest environment.

A Novel Design and Improvement of 15-Bar Assembly Tensegrity Robotics Structure
While the ultimate goal is to produce a tensegrity more than 6 struts, e.g. a 15-bar tensegrity, past experience has demonstrated that we must first develop an innovative system that will facilitate the assembly of a general n-bar tensegrity. To be successful, we believe the development of the new assembly methodology must encompass not only the design of the clamping system but also the design of the tensegrity itself, including the struts, the springs and the spring-to-strut connectors. We therefore propose to develop the 15-bar in two phases: Phase I will be the development of an innovative assembly method, and Phase II will focus on the design and manufacture of a 15-bar tensegrity, with a new strut design probably being part of this. Longer term goals will be aimed at repackaging the wireless electronics on the new struts and adding encoders to control the phase of the motors shafts.
