Blubber Bots are Do-It-Yourself robotic inflatables that navigate autonomously and intelligently. They are light-seeking helium-filled balloons that graze the landscape in search of light and cellphone signals.
The young Blubber Bots have emerged in an early stage of develpoment simliar to the incubating stages of an egg. All the parts are packaged into a Kit. You can download a pdf tutorial to learn what's involved in nurturing a Blubber Bot to its first flight.
