Blubber Bots are floating DIY robotic species that navigate autonomously and intelligently. Blubber Bots float, dance, seek and sing. They are light-seeking hellium-filled balloons that graze the landscape in search of light and cellphone signals. Designed into the inflatable form is a set of light sensors enabling them to seek out the brightest light source. They are also equipped with a phone flasher and can recognize cellphone activity. You can interact with a Blubber Bot by making a call and waving your phone near it. In response, it will go into a flocking dance or sing you a special tune. (alavs.com)
