Bring your very own robots to life with MOSS, a fun, all-ages robot construction system that requires no coding or wires, just your creativity. Power and data are sent through an elegant single button contact, while the ground passes through the steel spheres that connect using the powerful rare earth magnets embedded into the ABS plastic shells. With just one sphere, you make a ball joint; with two spheres, you make a hinge; and with three or four, you create a rigid structure. The function of your design is determined by a simple color-coded system. The green face conducts power; red and brown faces conduct data, red is output, brown is input; the blue pass-through face can pass any signal, either power or data. MOSS creations are powered with a rechargeable lithium polymer battery, rechargeable via micro-USB cable (included). Ages 8 years and up. Made in Colorado, USA.
