ⓘ Detailed Overview

Marvelmind's ultrasonic indoor positioning system delivers exceptional accuracy for multi-beacon tracking environments. This 16-second demonstration proves the capability to simultaneously track 4 mobile beacons with ±2cm precision—a performance standard required for demanding warehouse automation and autonomous robot applications. The system employs time division multiple access (TDMA) methodology, allocating bandwidth efficiently so each mobile beacon receives location updates at approximately 4Hz after accounting for switching overhead. Stationary beacon infrastructure mounted on facility walls creates a triangulation network that enables real-time position computation without relying on GPS or WiFi signals. Location data streams can be retrieved directly from mobile beacons or through Marvelmind's modem device connected via multiple interface options: USB, UART, SPI, or I2C protocols. This flexibility supports diverse integration scenarios including forklift tracking systems, indoor drone navigation, autonomous mobile robot (AMR) fleet management, and complex warehouse automation workflows. The ±2cm accuracy specification exceeds requirements for most indoor navigation tasks, enabling precise path planning, collision avoidance, and docking procedures. Organizations implementing Marvelmind's indoor positioning system gain a GPS-independent solution scalable from single-robot deployments to large-scale multi-beacon warehouse environments.
