ⓘ Detailed Overview

Marvelmind's ultrasonic indoor positioning system enables precise micro-drone tracking over extended distances by leveraging a multi-submap architecture—a critical capability for autonomous robotics in GPS-denied environments. This demonstration showcases real-world deployment with four interconnected submaps: three 2D submaps spanning a 50-meter corridor plus one 3D submap covering a 100m² room. The hardware configuration includes a single Micro-TX beacon mounted on the drone, eight Mini-RX stationary beacons positioned around the environment, and a central modem controller managing real-time location updates. Unlike traditional indoor positioning systems limited to single rooms, this multi-submap approach extends coverage to 150+ meters while maintaining centimeter-level accuracy. The starter set provides immediate deployment capability, with optional Mini-RX units for corridor coverage extension. This architecture addresses the fundamental challenge facing warehouse automation, indoor drone delivery systems, and autonomous robot navigation: reliable, continuous positioning across large industrial spaces. Marvelmind's ultrasonic technology achieves this without the signal degradation, reflections, or line-of-sight limitations common to UWB systems, making it ideal for complex indoor environments with obstacles and multiple rooms.
