The central function of each feral is to seek
out sources of environmental toxins. Different sources of toxins
emit specific materials, which are visible using a range of electronic
sensors. For example the ferals have been equipped for a release
at the English power station in NH, where we expect to encounter
high concentrations of, Co2, Co, and organic solvents as a result
of coal burning power generation. The sensors that the dogs are
fitted with for this release are sensitive only to these materials.
Type One: Stereo Sensing: Cloud:
The crux from a prototype standpoint is integrating real world data
collected by these sensors with the mechanics of the feral, allowing
the dog to move closer to the source of the material. For this purpose
each feral has two symmetrically opposite sensors enabling the dog
to gather two independent values simultaneously. From this data
the feral can compare these levels and determine the direction of
the source. Next, this determination is passed to the mechanics
moving the feral closer the source of the material.
Type Two: Directional Sensing:
Particulate: The ferals have also been modified to enable
the use of one sensor, as is the case with the dogs that are equipped
to sense terrestrial radioactivity. In this model the sensor is
attached to the dogs head, which is scanning from side to
side. Direction of the source is then determined again by making
a comparison of levels from each side. In order to use this model,
the sensor must be highly directional, i.e. it must see only what
is directly in front of it.
This point is the determining factor between which
of strategies to use, if the specifically chosen sensor can
tbe made directional than the dog needs two sensors. The configuration
of the sensors is specific to the material that is being sensed.
