Marvelmind demonstrates ultrasonic + IMU fusion achieving 80 Hz centimeter-level indoor 3D positioning

Marvelmind posted a demonstration on Reddit r/robotics: a mobile beacon rapidly traces a 30×30 cm square and moves back and forth along its two diagonals, with its position updated at 80 Hz and latency of about 12–20 ms, achieving centimeter-level XYZ tracking. The system consists of 3 fixed beacons plus 1 mobile beacon, using ultrasonic and IMU sensor fusion: ultrasound provides accurate absolute position updates, the IMU provides high-frequency motion data between ultrasonic measurements, and ultrasound continuously corrects the IMU's accumulated drift, thereby raising the update rate from about 8 Hz with ultrasound alone to 80 Hz. The company says this approach is suitable for scenarios such as autonomous drones, mobile platforms, and industrial automation in indoor GPS-denied environments.

- 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.
