Marvelmind Jacket: Robot & Drone Positioning | Marvelmind
Video Overview & Technical Details
Presents the new Marvelmind Jacket, a vest for precise indoor and outdoor tracking of people. Its key design point is robustness against the wearer’s own body: a Mini-RX with ultrasonic sensors on both sides, so the signal can be received from either side even when the neck or body blocks one, which keeps tracking reliable in more positions and conditions.

The Marvelmind Jacket is a vest for precise tracking of people indoors and outdoors: warehouse and production workers, construction crews, security staff. Its four microphones on the shoulders work as one large microphone - a distributed microphone system - so the wearer's own head, neck or body does not block the ultrasound and the tracking stays robust in any position.
0:01 Hello colleagues. Today we are showing our new version of Marvelmind jacket. So my online jacket is a vest effectively that can be tracked with about 20-centimeter precision. An alternative for the jacket is helmet and badge. We'll be discussing them later. So the jacket consists of the main element which is the Mini-RX, but it's more than just Mini-RX. I mean, it's clipped with a special holder, and additionally it has a sensor inside. So one sensor here, one sensor here, and inside, if you can check, there's a cable connecting. So effectively, it's done in order to minimize
1:00 the impact of obstruction by your own body. So it means that the signal, ultrasonic signal, can be received either from this side by this sensor or from this side by this sensor. And effectively, it means that in this direction you don't see, because your own neck prevents it—you don't see this—but then this sensor will be saying from this side. This sensor is not seen, but this is taking. So effectively, it increases the chances to get the data in all the conditions. So either one of these or both will be taken and received. So one more time: this is the new jacket bar by Marvelmind Robotics. Thank you.
Key Takeaways
- Precise tracking of people indoors and outdoors
- Four microphones on the shoulders, front and back, form a distributed microphone system
- The wearer's own head, neck and body do not block the ultrasound - the tracking stays robust in any position
- Built around the Mini-RX mobile beacon and worn as a normal vest
- For warehouses, assembly plants, construction sites and security - wherever people need to be tracked
Relevant For: Engineers & System Designers
Operations and safety managers, system integrators and engineers who need to know where people are in warehouses, factories and on construction sites. The Jacket solves the practical problem of tracking people: the person's own body must not block the signal, whichever way they turn.
FAQ
Technical Background & System Details
The Marvelmind Jacket is a wearable mobile beacon for tracking people, built around the Mini-RX. Its four external microphones sit on the shoulders - left and right, front and back - and are combined into one large microphone. This distributed microphone system solves the main problem of tracking people with ultrasound: the person's own head, neck and body can block the signal from one side. With microphones on both sides, the ultrasound from the stationary beacons is received whichever way the person turns, so the tracking stays robust while people walk, bend and work. The Jacket is used in warehouses, assembly plants, construction sites and security applications, and works both indoors and outdoors. For smaller form factors, see the Helmet and the Badge.
