--overheadbots------------------------------------------------------------- live on overheads, a bit like parasites they sit on top of the overhead and convert its light into their proper motion. ?the overheadbots are completely autonomous, all their energy is delivered by the overhead. the whole system is like a little ecosystem and works once the overhead is turned on without any further intervention.?the projected screen is like a 2 dimensional window to this world on the overhead projector, a world with real collisions, and unforeseeable events. on the other side the screen can also be seen as a an animated display, where color patches move around and form an ever-changing image. --technology------------------------------------------------------------- the overheadbots are actually simple sun-eaters based on mark tilden’s beam technology.(1) the only difference is that their solar-panel instead of facing upwards face downwards to the light of the overhead. some of the robots have a little loudspeaker attached in parallel to the motor so that whenever the robot moves, it also emits a little sound, a trick invented by ralf schreiber.(2) --exhibition history------------------------------------------------------- overheadbots were shown at the art of overhead festival for forgotten media, copenhagen denmark, 01.10.2005.(3) -- (1) mark tilden, http://www.nis.lanl.gov/projects/robot/ , http://solarbotics.com (2) ralf schreiber, http://www.ralfschreiber.com (3) the art of the overhead festival, http://www.overheads.org
