Abstract

With the global spread of the COVID-19 pandemic, ventilation indoors is becoming increasingly important in preventing the spread of airborne viruses. However, while sensors exist to measure wind speed and airflow gradients, they must be manually held by a human or an autonomous vehicle, robot, or drone that moves around the space to build an airflow map of the environment. In this demonstration, we present DAE, a novel drone-based system that can automatically navigate and estimate air flow in a space without the need of additional sensors attached onto the drone. DAE directly utilizes the flight controller data that all drones use to self-stabilize in the air to estimate airflow. DAE estimates airflow gradients in a room based on how the flight controller adjusts the motors on the drone to compensate external perturbations and air currents, without the need for attaching additional wind or airflow sensors.

4 DEMONSTRATION DESCRIPTION In this demonstration, we will show how DAE can map the airflow of a small and blocked off space. The drone will fly around this space, estimating and mapping airflow gradients in real-time. Additionally, we will have items that generate stronger airflows on hand (e.g., hair dryers and vacuums), which we will use to change the airflow of the demonstration area to show how DAE can measures changes in airflows.
