 Research Workshop at RoboSoft 2023 Singapore
Bi- & Multi-Stability in Soft Robots

April  3, 2023

Marina Bay, Singapore

Home: Overview




Bi- and multi-stable elastic structures rapidly release stored strain energy during transitioning between different equilibria shapes. These snap-throughs transitions between stable configurations allow to generate rapid and amplified deformations in elastic structures. Recently, the application of bi- and multi-stability to soft actuators and robots has attracted a growing amount of research interest. A wide range of innovative uses of bi- and multi-stability have been demonstrated.

These include single-input control mechanisms, high-speed actuations for jumping robots, major shape reconfigurations, adaptive sensing and mechanical logic computations. This workshop aims to present recent developments and to connect between researchers working on leveraging multistability in the field of soft-robotics.
