Low-Cost Soft Robotics Breakthrough
Oxford University has developed a technique to cut soft robotics fabrication costs to under $0.10 per actuator [https://miragenews.com/new-technique-could-slash-soft-robotics-costs-1633221/]. This makes rapid prototyping and DIY robotics more accessible than ever [https://miragenews.com/new-technique-could-slash-soft-robotics-costs-1633221/].
The new method uses thermoplastic vacuum pouches, a vacuum sealing machine, and a laser cutter, bringing the actuator cost down to just $0.10 per unit. The fabrication time is also reduced to under 10 minutes. This breakthrough democratizes soft robotics, making it accessible for education, startups, and research labs. Previously, soft robot manufacturing relied on methods like silicone molding or specialized 3D printing, which were costly and time-intensive. A gripper made using this technique can lift 25 times its own weight. The actuators can also endure up to 100,000 inflation-deflation cycles, demonstrating their durability. Soft robotics, which uses flexible materials like silicone and rubber, offers advantages over traditional rigid robots, including improved collision resistance and complex motion. Applications range from delicate object handling to search and rescue. The first real-world application of soft robotics was the McKibben artificial muscle, developed in 1950. Since then, soft robots have been developed for prosthetics, exoskeletons, and even internal surgery. Oxford University Innovation has created over 300 new companies since 1988 and is the top university patent filer in the UK.
