Editing BEAM robotics (section)

===Types===

There are various "''-trope''" BEAMbots, which attempt to achieve a specific goal. Of the series, the phototropes are the most prevalent, as light-seeking would be the most beneficial behaviour for a solar-powered robot.

* Audiotropes react to sound sources.
** ''Audiophiles'' go towards sound sources.
** ''Audiophobes'' go away from sound sources.
* Phototropes ("light-seekers") react to light sources.
** ''Photophiles'' (also ''Photovores'') go toward light sources.
** ''Photophobes'' go away from light sources.
* Radiotropes react to [[radio frequency]] sources.
** ''Radiophiles'' go toward RF sources.
** ''Radiophobes'' go away from RF sources.
* Thermotropes react to heat sources.
** ''Thermophiles'' go toward heat sources.
** ''Thermophobes'' go away from heat sources.
