This Transformers-looking robot stands, walks, and rolls by shape-shifting itself. Mori3 is a modular, origami-inspired robot that consists of a series of triangular modules that can be connected to each other in various ways to create polygons of different sizes and configurations. Developed by researchers at Switzerland's Ecole Polytechnique Fédérale de Lausanne (EPFL), Mori3 demonstrates the potential of modular robots for a wide range of tasks in space and other challenging environments. | G
