– **Changing Shape**: They can alter their shape to navigate around obstacles or through gaps².
– **Resilience to Damage**: Soft materials are more resistant to damage from impacts or falls, which is beneficial in unpredictable environments⁶.

The concept of soft grippers in robotics revolves around the use of compliant and adaptive mechanisms to manipulate objects gently and effectively. Unlike traditional rigid grippers, soft grippers are made from flexible materials that can conform to the shape of the objects they are handling. This allows for a more delicate and versatile grip, which is particularly useful for pick-and-place tasks, food handling, and manipulation of fragile objects.

Soft grippers typically employ **pneumatic actuators**, **soft materials**, or **shape-changing structures** to achieve this adaptability:
– **Pneumatic Actuators**: These use air pressure to inflate or deflate sections of the gripper, causing it to bend, twist, or wrap around an object.
– **Soft Materials**: Materials like silicone elastomers can be used to create grippers that are inherently flexible and can conform to various shapes.
– **Shape-Changing Structures**: Some soft grippers can change their form in response to stimuli, allowing them to adjust their gripping strategy for different objects.

These grippers are designed to mimic the natural compliance and dexterity found in biological systems, such as the tentacles of an octopus or the fingers of a human hand. By integrating sensors and advanced control systems, soft grippers can perform complex tasks with a high degree of sensitivity and precision, making them suitable for a wide range of applications in both industrial and medical settings¹²³⁴.

In summary, soft grippers represent a significant advancement in robotic manipulation, offering the ability to handle a diverse array of objects with care and efficiency, which is especially beneficial in industries where damage to the items being handled must be avoided⁵⁶.
