ⓘ Detailed Overview

Marvelmind's indoor positioning system delivers centimeter-level accuracy for autonomous indoor robots, drones, and warehouse vehicles operating in GPS-denied environments. This video demonstrates real-time tracking of two mobile beacons held simultaneously, proving the system's capability to monitor multiple mobile assets without interference. The architecture uses time division multiple access (TDMA) multiplexing, enabling each beacon to achieve approximately 8Hz update rates while sharing the ultrasonic infrastructure. Stationary reference beacons mounted on walls create a precise indoor coordinate system, while mobile beacons transmit their calculated positions via multiple interfaces including USB virtual UART, native UART, SPI, and I2C protocols. This flexibility makes integration seamless with flight controllers on drones, onboard computers in autonomous forklifts, or centralized warehouse management systems. The ±2cm positioning accuracy eliminates dead reckoning errors that accumulate in odometry-only systems, enabling reliable autonomous navigation in complex indoor environments like warehouses, manufacturing facilities, and logistics centers.
