Subject: [alt-beam] Re: easytrax!!!!!!!!!!!
I finally got it to install, but when I run easy edit I get an error, If I run it at the DOS promt it wants me to stick some disk into drive B. This is probably OLD software from what I've seen so far. Any help?

I can imagine a Queen which was essentially a large super cap bank or battery
with "brains" located in a hive safe from energy scavengers. The queen directs
a number of photovore workers which have much smaller energy storage pouches and
which are sent out to collect energy for the queen when the sun is bright. At
night the workers surround the queen, plug into the battery and go to sleep. For
the workers this is a low power standby mode to survive the night but at any
time a worker can be woken up by the queen to check if the sun is sufficiently
bright to harvest photo energy. When the worker comes back after a fixed time
interval with a full charge, the queen wakes more workers to forage light and
the cycle repeats. The queen would have strategies to survive long periods
without sun by keeping track of energy bank and projected remaining survival
time cutting off all but the most efficient worker until conditions improve and
she can sustain and recharge more workes to get the colony back on it's feet.
The pheromones could be a command sequence injected into a worker's command loop
(ie a special microcore which activates sensors and behaviour) and if the
broadcast bit is enabled, the worker may share the command sequence by contact
or low power IR tx with other workers throughout the hive. A sound beacon may
be used for long range communication (audiotropic) and to guide full
(photophobic) workers back to the hive. Once the majority of the workers energy
pouch is discharged into the "bank" the empty workers to become audiophobic and
phototropic to go back outside and find the brightest place to recharge their
"energy pouch". Other commands from the queen may cause workers to temporarily
feed each (communal) other in order to pick up strays which are stranded without
energy in dark places. This relatively complex social organization consists of a
small number of simple phototropic/photophobic, claustrophobic, audiophobic,
communal , solitary type behaviour circuits which in principle can be
"programmed" in the BEAM hardware language. More complex behaviours can be
generated if workers had a memory loop to remember the path taken from the
foraging site to the hive and a status loop to communicate light level and
charging rate etc. That way the queen could command other workers to follow
particularly successful worker and maximize energy harvesting in a bright light
pool.
I'm just describing an imaginary model of bot social organization but it is
clear that this level of complexity could be within the reach of simple micro
controller if not beam technology.
