Engineers at the University of California San Diego have developed a low-cost, low-power technology to help robots accurately map their way indoors, even in poor lighting and without recognizable landmarks or features.

The technology consists of sensors that use WiFi signals to help the robot map where it’s going. It’s a new approach to indoor robot navigation. Most systems rely on optical light sensors such as cameras and LiDARs. In this case, the so-called “WiFi sensors” use radio frequency signals rather than light or visual cues to see, so they can work in conditions where cameras …
