Soft robotic gripper

Definition

A soft robotic gripper is a flexible and adaptable device designed to grasp and manipulate objects of varying shapes and sizes using soft materials and compliant mechanisms. These grippers often mimic the way natural organisms, like octopuses or elephants, use their appendages to grasp items without causing damage, making them particularly useful in delicate handling tasks. The integration of biomimetic designs in soft robotic grippers enhances their ability to operate in unstructured environments and improves their versatility in applications such as manufacturing, healthcare, and even space exploration.
