Soft Actuation

Definition

Soft actuation refers to the mechanism by which soft robots achieve movement and control through flexible materials and structures, rather than traditional rigid components. This approach allows for more adaptable and compliant motion, enabling soft robots to navigate complex environments, such as those found in space exploration, where versatility and gentleness are crucial for interacting with fragile surfaces and systems.
