The researchers named their robots "OrigaMechs," short for Origami MechanoBots. Once cut, folded and assembled, the sheet transformed into an autonomous robot that can sense, analyze and act in response to their environments with precision. They then programmed the sheet with simple computer analogical functions that emulate those of semiconductors. A study detailing the research findings was published in Nature Communications.īy embedding flexible and electrically conductive materials into a pre-cut, thin polyester film sheet, the researchers created a system of information-processing units, or transistors, which can be integrated with sensors and actuators. Now, a multidisciplinary team led by researchers at the UCLA Samueli School of Engineering has created a new fabrication technique for fully foldable robots that can perform a variety of complex tasks without relying on semiconductors. The semiconductor-based components therefore have to be added after a robot has taken its final shape. However, the rigid computer chips traditionally needed to enable advanced robot capabilities - sensing, analyzing and responding to the environment - add extra weight to the thin sheet materials and makes them harder to fold.
