The University of Florida and the South Florida Water Management District developed the python-hunting tech this year, crafting remote-controlled, solar-powered stuffed rabbits that look and even smell like the real thing. The robo-rabbits also emit a realistic heat signature, sending the message to heat-sensing snakes in nearby swamps that dinner is served. Unbeknownst to the snakes, the robotic rabbits are also equipped with cameras that scan for pythons who have taken an interest in them.
