Close Robot Encounters of the Third Kind
EPFL researchers have designed a bio-inspired robot with a novel trimmed helicoid structure that allows for a wide range of motion and safe interaction with humans
At EPFL’s CREATE lab, under the guidance of Josie Hughes, a breakthrough has been made in the realm of soft robotics. Drawing inspiration from the versatile movement of elephant trunks and octopus tentacles, the team introduced the trimmed helicoid — a novel robotic structure that promises greater compliance and control in robotic designs. With a blend of keen biological observation and computational modeling, the researchers have now unveiled a soft robot arm capable of intricate tasks, ensuring safer human-robot interactions. The findings, detailing both the structure and methodology, are a collaboration with the Department of Cognitive Robotics at TU Delft and were published in Nature’s new journal, npj Robotics.
Professor Hughes highlighted the importance of this development: “Through the invention of a new architectured structure, the trimmed helicoid, we’ve designed a robot arm that excels in control, range of motion, and safety. When the novel architecture is combined with distributed actuation— where multiple actuators are placed throughout a structure or device—this robot arm has a vast range of motion, high precision, and is inherently safe for human interaction.”
