Ultrasonic RAdar System (URAS): Arduino and Virtual Reality for a Light-Free Mapping of Indoor Environments

Recently, academia and industry have focused on the creation of new systems for mapping and exploration of unknown spaces in order to create advanced guide systems for robots and people affected by disabilities. In particular, the most common applications are related to the exploration of unknown and/or dangerous spaces that are not accessible to people by exploiting the advantages offered by ultrasonic technology. This work aims at designing a new low-cost system, namely, ultrasonic radar system, to blindly map environments by using ultrasonic sensors, then displaying the acquired information through an Android-based device.
