Accelerometers, Gyros, GPS, & Compasses. Measure acceleration and track rotation with these accelerometers, gyroscopes, compasses/magnetometers, and combined inertial measurement units (IMUs) and orientation sensors.
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. Indoor Positioning System (IPS)
This is a programmable autonomous robot prebuilt kit that can be controlled via Gamepad. The MarvelMind IPS (Indoor Positioning System) provides indoor navigation. BeagleBone Black (Rev C) microcontroller provides the most flexible platform possible.
