Marvelmind Starter Set HW v4.9-IMU Indoor Navigation Positioning System (433MHz)

• Precise (±2cm) Indoor "GPS" navigation system for autonomous robots and systems
• Indoor localization of objects and humans equipped with beacons
• Coverage radius of a beacon: up to 50 meters
• Can be used for automatic delivery, drones, virtual reality, advertising and other fields
• Contains a mobile beacon with IMU that allows much faster update rate – up to 100Hz and above

The Indoor Navigation Positioning System Starter Set w/ Case & IMU (433MHz) is a system of stationary ultrasonic beacons united by radio interface in ISM band. Location of a mobile beacon installed on a robot (copter, human) is calculated based on the propagation delay of ultrasonic signal to a set of stationary ultrasonic beacons using trilateration. The kit consists of one mobile beacon, four stationary beacons and one router.

Beacons:
Beacons are mounted on walls or ceilings to measure distance to other beacons and “hedgehog” using ultrasonic pulses. They communicate with router wirelessly in ISM band. Powered by LiPo battery or USB. With IMU+Ultrasonic sensor fusion, update rate is increased to 100Hz with latency 12-15ms. Available only for the mobile beacons with IMU onboard.

Mobile beacon (“hedgehog”):
They are installed on robots and connected to it via UART or SPI or I2C or USB. Calculated coordinates (±2cm) are sent to the router and updated 16 times per second. Powered by LiPo battery or USB or from robot.

Router:
The router is the central controller of the system which calculates position of mobile beacon (“hedgehog”) 16 times per second based on data from beacons. They communicate via USB with dashboard and with beacons wirelessly in ISM band.

Features:

• High-precision (±2cm) indoor navigation system for autonomous robots and systems (“indoor GPS”) 
• Indoor tracking and positioning of objects and humans equipped with beacons
• Coverage radius of a beacon: up to 50 meters
• Supports USB, UART, SPI and I2C interfaces on mobile beacon
• Radio interface: 433MHz & 10mW - up to 100m in office environment
• Up to 1300h (>100 days with 12h/day & 1Hz location update rate) in active mode when powered from battery. Up 2y in deep sleep mode

Uses:

• Advertising
• Gaming and hobby
• Automatic delivery
• Dangerous places
