Instant Wild satellite cameras protect animals through crowdsourcing (video)
Remote cameras are useful to wildlife conservationists, but their closed (or non-existent) networking limits the opportunities for tracking animals around the clock. The Instant Wild project's cameras, however, are designed to rely on the internet for help. Whenever they detect movement, they deliver imagery to the public through Iridium's satellite network. Anyone watching the cameras through the Instant Wild iOS app or website becomes an impromptu zoologist; viewers can identify both animals and poachers that dedicated staff might miss. Maintenance also isn't much of an issue, as each unit is based on a Raspberry Pi computer that can run for long periods on a single battery. The Zoological Society of London currently operates these satellite cameras in Kenya, but there are plans underway to expand their use to the Antarctica, the Himalayas, Indonesia and Sri Lanka.
Fish are lazy, naive, easily led by robots (video)
What does a fish look for in a leader? No doubt a nice fishy smell is important, and maybe a sense of direction too, but the overriding factor happens to be something much simpler, and indeed simple enough for a robot to mimic. Our old friend Maurizio Porfiri and a colleague from New York's Polytechnic Institute have shown that a fish-bot will quickly attract live followers if it has a nice, fluid swimming motion. When the stroke is just right, real fish will pull up alongside and visibly relax their own motion to conserve energy, just like geese flying at the rear of a 'vee' formation. It's hoped that, in the future, robots might be used to guide endangered fish populations away from oil spills and other calamities, in much the same way as battery-powered leaders have guided humanity since the dawn of time (allegedly).
