  • 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 that primarily uses simple analog
    circuits instead of a microprocessor in order to
    produce an unusually simple design (in comparison
    to traditional mobile robots) that trades
    flexibility for robustness and efficiency in
    performing the task for which it was designed.

7
Mechanisms and Principles
  • The basic BEAM principles focus on a
    stimulus-response based ability within a machine.
    The underlying mechanism was invented by Mark W.
    Tilden where the circuit is used to simulate
    biological neuron behaviors. Some similar
    research was previously done by Ed Rietman in
    'Experiments In Artificial Neural Networks'.
    Tilden's circuit is often compared to a shift
    register, but with several important features
    making it a useful circuit in a mobile robot.

8
Shift Register
  • In digital circuits a shift register is a
    group of registers set up in a linear fashion
    which have their inputs and outputs connected
    together in such a way that the data is shifted
    down the line when the circuit is activated.

Types
  • Serial-In, Serial-Out

10
  • Serial-In, Parallel-Out

11
  • Parallel-In, Serial-Out

Disputes in the name
  • Various people have varying ideas about what
    BEAM actually stands for. The most widely
    accepted meaning is Biology, Electronics,
    Aesthetics, and Mechanics. However, there are
    many other semi-popular names in use, including
  • Biotechnology Ethnology Analogy Morphology
  • Building Evolution Anarchy Modularity

13
Types
  • Audiotropes react to sound sources.
  • Phototropes ("light-seekers") react to light
    sources.
  • Radiotropes react to radio frequency sources.
  • Thermotropes react to heat sources.

14
General
  • Sitters Unmoving robots that have a physically
    passive purpose.
  • Squirmers Stationary robots that perform an
    interesting action (usually by moving some sort
    of limbs or appendages).
  • Sliders Robots that move by sliding body parts
    smoothly along a surface while remaining in
    contact with it.

15
  • Crawlers Robots that move using tracks or by
    rolling the robot's body with some sort of
    appendage. The body of the robot is not dragged
    on the ground .
  • Jumpers Robots which propel themselves off the
    ground as a means of locomotion.
  • Rollers Robots that move by rolling all or part
    of their body.

16
  • Walkers Robots that move using legs with
    differential ground contact.
  • Swimmers Robots that move on or below the
    surface of a liquid (typically water).
  • Fliers Robots that move through the air for
    sustained periods.
  • Climbers Robot that moves up or down a vertical
    surface, usually on a track such as a rope or
    wire.
