Wearable interactive display for the local positioning system (LPS)

Abstract

Traditionally, localization systems for formation-keeping have required external references to a world frame, such as GPS or motion capture. Humans wishing to maintain formations with each other use visual line-of-sight, which is not possible in cluttered environments that may block their view. Our Local Positioning System (LPS) is based on ultra-wideband ranging devices and it enables teams of robots and humans to know their relative locations without line-of-sight. This demonstration shows live (real-time) local positioning between three agents (human and robot). The emphasis of this demonstration is showing the wearable interactive display that allows the human to see the local frame formation of the human and the robots.
