We have a precise (±2cm) indoor navigation system (Indoor “GPS”) that is designed to provide real-time location coordinates for autonomous robots, vehicles.
Demo how it works:
- youtu.be/ttOKjmNtpRE - a mobile beacon is traced in real time in small room
- youtu.be/PFgNPkLGCDk - a large scale (up to 30 meters between beacons) demo
Basics: You have stationary beacons (not Bluetooth or WiFi) every 10-50 meters. And you trace a mobile beacon on your robot with ±2cm precision. You get the coordinates either directly from the beacon on your robot via USB or UART or SPI or I2C; or you can get data from the central controller - depending on the needs of your system.
Detailed description of the protocol is available.
More information is on marvelmind.com/
I will be happy to provide you with more information, if needed.
The most important is that the system is readily available and you can get it within 5-7 days (shipping time)
