FAQ
Detailed Overview
Marvelmind's indoor positioning system delivers meter-accurate tracking through an innovative ultrasonic-based RTLS solution designed for autonomous indoor robots and warehouse automation. This demonstration proves the system's core capability: achieving ±2cm positional accuracy while continuously tracking a mobile beacon through a complex eight-loop path. The architecture employs stationary ultrasonic beacons mounted on walls that triangulate the position of moving beacons attached to robots, forklifts, or drones. Real-time position data updates at 16Hz, providing responsive feedback loops essential for autonomous navigation in GPS-denied indoor environments. The system flexibly outputs tracking data through multiple interfaces—USB (virtual UART), native UART, SPI, or I2C—enabling seamless integration with robot control systems, warehouse management platforms, and autonomous vehicle stacks. Unlike broad-range solutions, Marvelmind's ultrasonic approach eliminates multipath interference common in RF-based systems, delivering the precision accuracy required for docking, collision avoidance, and safety-critical warehouse operations. The modular beacon architecture scales from small research labs to large facility deployments, making it suitable for autonomous forklifts, AMRs, and industrial drones.
