At the University of San Diego, USA, researchers have developed a quick way to create insect-like flexible 3D robots. The structure of the robots was inspired by the exoskeleton of insects and has thus been named ‘flexoskeleton’. The low-cost, quick robots were printed without any special equipment— they were assembled in less than two hours, with each component taking about 10 minutes to print. Each part costs less than $1 and the only expensive parts are the processing unit, sensors and battery. The robots are printed on polycarbonate sheets. After carefully observing the behaviour of insects, the researchers added minimal features to their robots to increase rigidity. The ultimate aim is to mass assemble the flexoskeletons without human involvement.
