BEAM robotics

The word "beam" in BEAM robotics is an acronym for Biology, Electronics, Aesthetics, and Mechanics. This is a term that refers to a style of robotics...

Robot

A robot is a mechanical or virtual intelligent agent that can perform tasks automatically or with guidance, typically by remote control. In practice a robot is usually an electro-mechanical machine that is guided by computer and electronic programming. Robots can be autonomous, semi-autonomous or...

 that does not move. Such robots have no self-contained means of transportation and are non-mobile. Instead of moving, sitters are usually designed to power lights in some sort of pattern. Most sitters are built as decorations rather than serving a practical purpose.

As sitters usually have few parts and are not very complicated to build, many newcomers to BEAM robotics start with sitters, as they are a good place to begin learning the basics of the hobby.

Genera

• Beacons : Transmit a signal (usually a navigational blip) for other BEAMbots to use, often as a navigational device. Essentially, these consist of a solar cell, capacitor, LED(s), and possibly a solar engine. Beacons are often found within robot games and are used by other robots to use as a "base" for navigation.
• Pummers : Display a "light show" or a pattern of sounds. Pummers are often nocturnal robots that store solar energy during the day, then activate during the night.
• Ornaments : A catch-all name for sitters which are not beacons or pummers. Many times, these are mostly electronic art
  Electronic art
  Electronic art is a form of art that makes use of electronic media or, more broadly, refers to technology and/or electronic media. It is related to information art, new media art, video art, digital art, interactive art, internet art, and electronic music...
