Bernd Diemer's Intruder exhibition at Weimar, Germany included the operation and control of multiple autonomous robots driving around tracked visitors of the interactive space.
The tracking hard- and software was designed an implemented by me. The system used a IR beam generated at a particular frequency via the Sound-Card of a PC. Multiple IR LEDs are driven by an audio amplifier. The Robots have IR receivers with two independent Tone-Decoder IC on board. Using multiple different audio frequencies, the PC can generate specific trigger sequences received by the robots. The trigger sequences turn on ultrabright, red LEDs arranged in a triangle shape. A video camera with red-filter images the scene and determines the location and direction of the triggered robot from the image. The information is made available via a TCP/IP interface to the control software. Software ImagesSee also www.martinahaitz.de
