Accelerometers, Gyros, GPS, & Compasses. Measure acceleration and track rotation with these accelerometers, gyroscopes, compasses/magnetometers, and combined inertial measurement units (IMUs) and orientation sensors.
This is a ROS programmable autonomous SLAM robot prebuilt kit that can be controlled via Gamepad. The MarvelMind IPS (Indoor Positioning System) provides indoor navigation. ODROID-XU4 SBC provides the most flexible platform possible.
Mount beacons 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. The beacon has a built in Inertial Measurement Unit (IMU).
