Marvelmind demonstrates centimeter-level real-time 3D positioning for autonomous robots: fast tracking along a 30 cm square path

Marvelmind demonstrates high-precision 3D positioning in indoor GPS-denied environments: a mobile beacon moves quickly along a 30×30 cm square, with positioning updated at 80 Hz and latency of 12–20 ms, achieving centimeter-level XYZ tracking. The system uses 3 fixed beacons plus 1 mobile beacon and, through ultrasound and IMU sensor fusion, raises the ultrasound update rate of about 8 Hz to 80 Hz; it is suited to indoor autonomous drones, mobile platforms, and industrial automation scenarios.
