Researchers at the University of Edinburgh have achieved a remarkable breakthrough in robotics. They developed a soft robot that prints in one piece and walks right after. This cutting-edge innovation, introduces the “Flex Printer” — a low-cost, open-source 3D printing system designed to make soft robotics more accessible.
A Leap Forward in Soft Robotics
Soft robotics uses flexible materials for safer, adaptable machines, but high costs made them hard to build. The Flex Printer solves this by printing complete, ready-to-walk robots in one go—no assembly or electronics needed.
How the Flex Printer Works
Notably, the Flex Printer can be built using off-the-shelf parts for under £400 (approximately $500). Moreover, the design is simple enough for users with basic technical skills to construct and operate within a few days. The system prints the robot upside-down; then, once printing finishes, a user connects it to a compressed air source. At that point, the robot comes to life — walking straight off the print bed.
Expanding Possibilities
This advancement opens the door to a wide range of applications. For example, soft robots could safely assist in biomedical procedures, navigate hazardous environments in nuclear facilities, or even explore other planets. Because these robots don’t require electronics, they are particularly well-suited for operations in explosive or delicate environments where conventional robots might fail.
In short, this achievement represents a major step toward more affordable, practical, and safe robotic systems. By literally allowing soft robots to walk out of the printer, the Flex Printer might redefine the way we think about robotics manufacturing.
