How Soft Robotics is Transforming the Way We Approach Manufacturing

I. Introduction

Soft robotics is a subfield of robotics that focuses on creating robots from compliant materials that can deform and adapt to their environment. Unlike traditional rigid robots, soft robots are constructed from materials such as silicone, rubber, and other flexible substances, allowing them to handle delicate objects and navigate complex environments safely.

Traditional manufacturing methods often rely on rigid robotic systems that can be limited in their functionality and adaptability. These systems are designed for specific tasks, which can make them less efficient when faced with varying production requirements or the need for precision handling of fragile components.

As industries continue to evolve, innovation in manufacturing processes is essential. The integration of soft robotics presents an opportunity to enhance efficiency, improve product quality, and reduce operational costs.
