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. Credit: UCLA Samueliīy 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. A study detailing the research findings was published in Nature Communications.Ī Venus flytrap-like robot that envelops a “prey” when both of its jaw sensors detect an object. 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. As a result, the semiconductor-based components must be added after the robot has been formed into its final shape. However, the conventional requirement of rigid computer chips, which enable advanced capabilities such as sensing, analyzing, and adapting to the environment, adds extra weight to the delicate sheet materials and makes them difficult to fold. These lightweight robots are more straightforward and cost-effective to manufacture, and their more compact form makes them more convenient for storage and transportation. Roboticists have adopted a method resembling the traditional art of paper folding to fabricate autonomous machines from thin, pliant sheets.
