A robot that finds its own position indoors without LiDAR, which is expensive, or
cameras, which raise surveillance concerns. It will combine an IMU with beacons placed
around the room, working like an indoor GPS, and laser ranging. This board is the
first step: analog motion sensors read by a 24-bit ADC and an STM32.
