    A network of stretchable optical waveguides is created and tested under locally applied lateral force and stretching. The network is comprised of urethane waveguides formed into interconnected junctions. These junctions split light pulses sent from a time-of-flight sensor, causing them to travel down different paths throughout the network and are input agnostic. The different split pulses' arrival times and amplitudes can be used to detect these deformations, differentiate between types of deformations and locate which junctions they occurred between.le

    You can print anything... or can you? 3D printing is an exciting new technology that promises to very quickly create anything people can design. Scientists who want to make soft robots, like Baymax from Big Hero 6TM, are excited about 3D printers. Our team uses 3D printing to make molds to produce soft robots. Molding is like using a muffin tin to make cupcakes. But can you make anything with 3D printing or are there times when 3D-printed molds do not work? Just like a cupcake liner, 3D-printed molds leave ridges, like a Ruffles potato chip, in soft robots. These ridges are a weak point where cracks can form, causing the robot to pop like a balloon. To prevent this, we sometimes need to make our robots using very smooth molds made from metal. This article talks about when and how 3D printing is useful in making soft robots.
