I develop a small toy setup with a pair of Arduinos and some ultrasound sensors to do object localization. The goal is to have at least 4 echo distances in each measurement to assert a unique solution of the localization equations. In addition to the position I also want to compute some validation criteria.
The Hardware I’m using two Arduino Unos and 6 HC-SR04 ultrasonic sensors. Each Arduino is in control of 3 sensors and the sensors are placed in two rows of 3 sensors each (see below).
