Interactive sound art installation by vtol features a remote controlled robot with speaker playing sounds from canvases covered in cassette tape:
A wheeled remote-controlled robot roams around the horizontal
black-striped canvas. These stripes are nothing else than audiocassette
tapes. The robot is equipped with two tape heads to read off the
magnetic tape. When the sound head crosses the tape or moves along it,
it reads off the sound and forwards it over the radio to the computer
and to the small loudspeaker placed on the robot. A customized remote
control is used to operate the robot. A joystick is installed on the
remote control to guide the robot; there are also buttons to manipulate
the sound. This device can create music loops out of the sounds
captured, control the sound processing and set up different parameters.
Robot and sound transmission are controlled via Bluetooth.
Some of the tapes have several records of audiobooks by Stanislaw Lem. Others carry random records of unknown origin.
