Engineers Successfully Develop 3D-Printable Soft Robots Capable of Ambulatory Movement
Researchers at the University of Edinburgh have developed a groundbreaking 3D printing system to create soft robots capable of independent movement. These flexible, four-legged devices, made from compliant materials like soft plastics, have significant potential in fields such as nuclear decommissioning, the biomedical sector, and space exploration, according to the scientists.
The innovation lies in an upside-down 3D printing method and a low-cost desktop system that overcomes technical and financial barriers previously hindering the mass production of such devices. The user-friendly setup can be assembled for under £400 using off-the-shelf parts.
The robots are made entirely from soft plastic and powered by air pressure, eliminating the need for complex assembly or electronics. Once printed, the robots are connected to a compressed air supply and walk out of the printer on which they were created.
Researchers believe this could lead to the creation of intelligent soft robotic systems without electronic parts. Lead engineer Maks Gepner stated that the new platform makes it possible for anyone to print things previously thought to be impossible, potentially revolutionizing engineering and art.
The team has made their designs publicly available to broaden access to soft robotic technologies and encourage collaboration and improvements to the system. The research was funded by the Engineering and Physical Sciences Research Council and published in the Journal of Device.
The Flex Printer system, requiring little prior knowledge to assemble and operate, is designed to be easily accessible to research institutions, educators, and hobbyists. First-time users can assemble it and start creating robots in just a few days.
By standardizing the manufacturing process, removing the need for electronics, and offering a low-cost solution, this approach addresses longstanding challenges in soft robotics, potentially enabling wider adoption and innovation in various industries.
- This 3D printing method, applicable to various industries like nuclear decommissioning and space exploration, not only involves the use of science in creating soft robots but also incorporates technology through the development of the Flex Printer system.
- The revolutionizing idea of printing complex structures without electronics, such as soft robots, signifies the merging of science and technology, potentially bringing about a future where the physical boundaries of engineering and art are redefined.
