A robot light is a type of lighting that has automatic or mechanical capabilities that go beyond traditional fixed lighting. Such lights can produce complex and clever effects, but the algorithm is in the hands of human users such as light designers, control system programmers, or light operators, not inside the light fixture itself. Therefore, robot lights (ILS), also known as automatic lighting, moving lights. Over time, as features such as color changing and focusing became widespread in other shipowners, the term "robot light" began to be no longer used in some cases. Historical Development The history of the robot light dates back to a lamp used by Edmond Sohlberg of Kansas City, USA in 1906, using a carbon-arc bulb and powered by cords that manually controlled pan, tilt and zoom. In 1925, the rigging was moved by electric motors for the first time by Herbet F. King, and with it the position of the light beam was changed.
Later in 1936, US patent number 2,054,224 was granted for a similar Business & Consumer Email List device in which pan and tilt control was provided by a joystick rather than buttons. In 1969, George Izenour designed the first rigger that directed a beam of light remotely. In Bristol, developments were being made for music events, at which time Century Lighting (now Strand) began selling specially ordered moving rigs. Vari-Lite and Digital Control In 1978, a light and sound company based in Dallas, Texas, called Showco, began developing a lighting fixture that used color-changing rotating diachrosis filters. During development, designers decided to add motorized lighting with pan and tilt. Showco transformed this project into a company called Vari-Lite, and the first shipowner was named Vari-Lite.
Genesis trialled this rig in a stable in England in 1980 and agreed to fund the project. This technology spread rapidly throughout the music industry, with Vari-Lite ordering 55 riggers for its first concerts. In 1986 Vari-Lite introduced a new line of lighting fixtures and control consoles. Control Methods Robot lights can be controlled in many different ways. Usually shipowners connect to a light control desk and send out the control signal. This control signal can generally be transmitted in three ways: analog (not widely used), DMX (Digital Multiplex, industry standard control protocol), or Ethernet Control (such as ArtNet or sACN). DMX protocol is controlled by the majority of mobile riggers. Each rigger is assigned to a specific block of DMX channels in a DMX universe (a set of cables and riggers with a maximum of 512 channels).
