Omni-Microphone-IP67 for Precise Indoor Positioning and Navigation System

Omni-microphone is an advanced all-directions microphone for robots and forklifts when the highest performance and the largest submaps are required.

  • Omni-Microphone is an external microphone that can be used along with Super-Beacons and Mini-RXs. On request, it can also be used along with Industrial-RX and Industrial Super-Beacons. The later support in HW and SW, but an additional modification of housings is required
  • It has a super-wide 360×360-degree beam, i.e. Omni-directional pattern
  • It is possible to enable and receive signals from any of the microphones separately, thus, disabling a noise source from an unwanted direction because the Omni-Microphone consists of 4 external microphones back to back
  • The Omni-Microphone is great for Direction + Location, for example, for robot’s
  • It is highly recommended for larger submaps (25m+) or when a particularly guaranteed and robust tracking of a forklift or similar mobile object on the largest possible distance. See the video for more info about microphone diagrams
  • The microphone is IP67 protected by special membranes and compound
  • The microphone requires soldering. There are easy to use pins on the board and connectivity is described in the Operating Manual
  • Only one Omni-Microphone can be connected to a Super-Beacon or to a Mini-RX, because, effectively, there are four microphones inside already
  • Read more about connectivity to beacons in the Operating Manual on the manufacturer’s website

Product Manuals

If applicable, the Product Documentation, Brochure, Reference Materials, CAD design(s),.STEP file(s) and other drawing files, Manuals, and Tutorials will be available for download upon purchase.

Marvelmind Indoor Navigation System is an off-the-shelf indoor navigation system, designed to provide precise (±2cm) location data to autonomous robots, vehicles (AGV), and copters. It can also be used to track moving objects via mobile beacons attached to them. Other applications include, for example, forklifts, virtual reality (VR) systems, helmets for construction workers or miners, etc.

The navigation system consists of a network of stationary ultrasonic beacons interconnected via a radio interface in a license-free band, one or more mobile beacons installed on objects to be tracked, and a modem providing a gateway to the system from PC or other computers.

A mobile beacon’s location is calculated based on a propagation delay of ultrasonic pulses (Time-Of-Flight or TOF) between stationary and mobile beacons using a trilateration algorithm.

The system can build the map of stationary beacons automatically. In simple cases, no additional manual data input or any manual distance measurements are required. This map formed once can be frozen and stored in the modem’s memory and the system becomes fully active within 7 to 10 seconds after the modem is powered.
