MARVELMIND NAVIGATION SYSTEM OVERVIEW Marvelmind Indoor Navigation System designed to provide precise (±2cm) location data to autonomous robots, vehicles (AGV), and copters. It also used to track other objects that the mobile beacon installed on, for example, virtual reality (VR) systems, helmets for construction workers or miners, etc. MARVELMIND BEACON OVERVIEW Mobile and stationary beacons do not differ externally and physically Mobile beacon Installed on robot and interacts with it via UART or SPI or I2C or USB Receives location update from router up to 45 times per second Contains IMU (accelerometer + gyroscope + compass module) Stationary beacon Mounted on walls or ceilings Measure distance to other beacons using ultrasonic pulses (time-of-flight) Communicate with router wirelessly in ISM band Distance between beacons-neighbors is up to 50 meters (in real life up to 30 meters)
