The recent article in Advanced Functional Materials titled “Low‐Volume Cores for Fabrication of Compact, Versatile, and Intelligent Soft Systems” outlines a novel approach to soft robotic systems‘ fabrication. This technique utilizes thin, flexible thermoplastic sheets to mold internal chambers, paving the way for compact and sophisticated designs. Such advancements offer a new horizon for creating low‐volume networks within soft actuators, promising varied applications in robotics.
Fabrication Method
The low‐volume core (LVC) fabrication method focuses on embedding thin and flexible thermoplastic sheets within soft fluidic actuators, valves, and circuits. This approach generates low‐volume networks, or LV-net actuators, enabling the creation of actuators with complex geometries and multiple degrees of freedom. Additionally, the LVC method ensures the low actuation volume input, making the systems more efficient and compact.
This technique also extends to completely soft, monolithic logic components, such as LV valves, which provide directional resistance and act as switching mechanisms. These valves contribute to the fluidic logic within soft systems, enhancing the versatility and integration of soft robotic systems.
Applications and Integration
The LVC fabrication method’s compatibility with both actuators and valves is significant for developing integrated, multifunctional soft robotic systems. The study showcases two intelligent soft robotic systems that merge LV-net actuators with LV valves, illustrating the method’s effectiveness in complex system fabrication. These examples highlight the potential for creating advanced soft systems with embodied intelligence.
Compared to prior methods, this novel approach stands out by offering a means to fabricate intricately designed components that are compact and capable of multi-degree-of-freedom actuation. This capability is critical for advancing the field of soft robotics, where system efficiency and compactness are essential.
Earlier studies on soft robotic systems primarily focused on simpler designs that lacked the compactness and versatility introduced by the LVC method. While previous efforts made strides in achieving flexible and functional soft actuators, they often faced limitations in creating integrated systems with embedded intelligence. The current method addresses these challenges by enabling the design of more complex and efficient systems.
The innovation in using low‐volume cores within soft robotic devices marks a significant shift from traditional fabrication techniques. Previous works did not employ the same level of sophistication in integrating actuators and valves, leading to bulkier and less efficient systems. The LVC method offers a refined solution that could reshape the future of soft robotics.
The LVC fabrication method’s introduction signifies a potential leap forward for soft robotic systems. By enabling the creation of intricate, compact, and versatile components, this method paves the way for advancements in the field. The compatibility of this technique with various soft robotic elements ensures enhanced functionality and efficiency. Moreover, the demonstrated integration of LV-net actuators and LV valves showcases the method’s capability to produce intelligent, multi-functional systems. For those invested in soft robotics, understanding and leveraging this method could be crucial for future innovations.
