Resumen de Sneaky ninja robot silently films its prey
A robot that moves only when it won't be seen or heard might make it easier to sneak upon animals and film them in the wild. Defense labs have built robots that track people through cities, avoiding well-lit areas. But cities are noisy, so if a robot keeps a certain distance it's unlikely to be heard. Tracking and filming animals in the wild is tougher because they often have keen hearing and the environment is usually quieter. Matthew Dunbabin and his team at the CSIRO Autonomous Systems Laboratory in Brisbane, Australia, are teaching a four-wheeled robot to move only when intermittent sounds will mask its movements. With the help of a camera, laser scanner and the right algorithm, the robot can figure out which vantage points will provide the best cover so it can skulk in the shadows.
