Robotic arms have long been associated with hard, rigid structures that prioritize precision and efficiency. However, researchers at EPFL and TU Delft have taken a different approach, leveraging the soft and pliable nature of elephant trunks and octopus tentacles to design a groundbreaking prototype arm. This revolutionary device combines flexibility, safety, and an expanded range of motion, showcasing its potential in various industries.
Using a unique architectural structure known as the trimmed helicoid, the scientists have created an arm that excels in control, offering enhanced maneuverability and precision. Unlike traditional robotic arms that only bend at the shoulder, elbow, and wrist joints, this innovation boasts a pliable and bendable core surrounded by an open-mesh structure. By selectively trimming polymer elements throughout the structure, the arm can bend and deform in multiple directions, making it safer for human interaction while protecting internal electronics and actuators from impacts.
With its soft exterior, this arm presents unparalleled safety features, making it ideal for applications that require close human interaction. Tasks such as fruit-picking, agricultural work, caring for the elderly, and assembly line operations could greatly benefit from this human-friendly robotic arm. Furthermore, the arm’s increased flexibility enhances its suitability to navigate complex environments and perform intricate tasks with exceptional precision.
The potential of this arm technology has not gone unnoticed. Under the spinoff company Helix Robotics, the EPFL and TU Delft researchers are actively commercializing this groundbreaking innovation. By bridging the gap between human and robot interaction, the soft-arm technology promises to revolutionize industries that demand flexibility, safety, and efficiency.
