"A team of researchers demonstrated that popular robotic household
vacuum cleaners can be remotely hacked to act as microphones.
The researchers—including Nirupam Roy, an assistant professor in the
University of Maryland's Department of Computer Science—collected
information from the laser-based navigation system in a popular vacuum
robot and applied signal processing and deep learning techniques to
recover speech and identify television programs playing in the same room
as the device.
The research demonstrates the potential for any device that uses light
detection and ranging (Lidar) technology to be manipulated for
collecting sound, despite not having a microphone. This work, which is a
collaboration with assistant professor Jun Han at the University of
Singapore was presented at the Association for Computing Machinery's
Conference on Embedded Networked Sensor Systems (SenSys 2020) on
November 18, 2020."
