Soft Manipulators

Definition

Soft manipulators are flexible robotic devices designed to interact safely and effectively with delicate objects and environments. Their unique structure allows them to adapt their shape and movements in response to external forces, which is rooted in the principles of continuum mechanics, enabling them to navigate complex terrains and manipulate items without causing damage. They are particularly useful in applications where traditional rigid manipulators would struggle, such as soft mobile robots, which benefit from the ability to move smoothly and handle various tasks in unstructured environments.
