Why they look like they do:
The design of the robots are physically integrated with the A.I. itself. In so doing the robot becomes more resilient and adaptive to a changing environment. It is our belief that to successfully integrate living & electronic components the robot must mimic a living thing, not a machine, in all respects.
"Thou shalt not make a machine in the likeness of a human mind."
Ecosystems respond to changes in their environment by various physical means. These can be detected by sensors. A phytogenic A.I. consists of (1) the 'control ecosystem' which is an ecosystem the robot maintains internally under ideal conditions. A hybrid analog-digital computer (2) monitors it. The computer also senses variations in the external ecosystem (3). It continuously calculates a "stress gradient" between the 2 ecosystems and reacts based on the results.
An ecosystem is not a discrete object. It is a name we give to the interaction among multiple species from all phylums. As such the "optimum conditions" for each species varies as it is influenced by weather, season AND it's interaction with other species. Therefore, the stress gradient is continuously changing. This implies that the "optimum" conditions are always a Nash Equilibrium.
