Unleashing Soft Modular Robots by means of a Bio-inspired Connection Strategy

Dario Floreano, William John Stewart, Davide Zappetti

Untethering can allow soft modular robots to move from the laboratory test bench into realistic environments and commercial use. However, today’s state of the art soft modular robots remain electrically connected to external power sources and controllers. ...

Dual Stiffness Tensegrity Platform for Resilient Robotics

Dario Floreano, Stefano Mintchev, Yi Sun, Davide Zappetti

Collision resilience is an important feature of robots deployed in unstructured and partially unpredictable environments. Herein, a novel dual stiffness (DS) tensegrity platform to integrate collision resilience into a robot body is proposed. The proposed ...

Seeking Quality Diversity in Evolutionary Co-design of Morphology and Control of Soft Tensegrity Modular Robots

Dario Floreano, Davide Zappetti, Davide Zambrano, Giovanni Iacca

Designing optimal soft modular robots is difficult, due to non-trivial interactions between morphology and controller. Evolutionary algorithms (EAs), combined with physical simulators, represent a valid tool to overcome this issue. In this work, we investi ...

Variable-stiffness tensegrity spine

Dario Floreano, Davide Zappetti, Enrico Ajanic, Roc Arandes Vilagrasa

Vertebrates, including amphibians, reptiles, birds, and mammals, with their ability to change the stiffness of the spine to increase load-bearing capability or flexibility, have inspired roboticists to develop artificial variable-stiffness spines. However, ...

Phase Changing Materials-Based Variable-Stiffness Tensegrity Structures

Dario Floreano, Jun Shintake, Davide Zappetti

Soft robots leverage deformable bodies to achieve different types of locomotion, improve transportability, and safely navigate cluttered environments. In this context, variable-stiffness structures provide soft robots with additional properties, such as th ...

A Soft Robot for Random Exploration of Terrestrial Environments

Dario Floreano, Stefano Mintchev, Davide Zappetti, Jérémie Willemin

A swarm of randomly moving miniature robots is an effective solution for the exploration of unknown terrains. However, the deployment of a swarm of miniature robots poses two challenges: finding an adequate locomotion strategy for fast exploration and obst ...

Bio-inspired Tensegrity Soft Modular Robots

Dario Floreano, Stefano Mintchev, Jun Shintake, Davide Zappetti

In this paper, we introduce a design principle to develop novel soft modular robots based on tensegrity structures and inspired by the cytoskeleton of living cells. We describe a novel strategy to realize tensegrity structures using planar manufacturing te ...
