The study, published in the journal Science Robotics, draws on biological knowledge of how ants use visual cues and step counting to navigate long distances.
Designed for robots weighing tens or hundreds of grams, the strategy uses sparse snapshots of the environment, like breadcrumbs, instead of detailed maps. By intelligently distributing these snapshots, the robots can save memory and efficiently return to their starting points after missions up to 100 meters long.
Equipped with an omnidirectional camera and controlled by a microcontroller, the 56-gram “CrazyFlie” drone demonstrated its ability to navigate 100 meters using just 0.65 kilobytes of memory.
