Flexible Actuation

Definition

Flexible actuation refers to the ability of soft robotic systems to generate movement and adapt to their environment through deformable mechanisms. This involves using materials and structures that can bend, stretch, and compress in response to external forces or inputs, allowing for versatile movement patterns and enhanced functionality. This adaptability is key in soft robots, enabling them to perform tasks in complex and unpredictable environments.
