A few of the settings (ones for, say, motor speed or level of contrast it looks for when seeking light) will be left for them to decide for themselves. When they sit out a cycle and go into a communications phase, they'll use IR LEDs to broadcast their efficiency level, and what their settings currently are. All the other 'bots in the immediate area will compare their own efficiency to the one broadcast, and nudge their own settings closer to the broadcasting 'bot's, or ignore them if they're doing better. Eventually, this yes/no better/worse behavior should help each other find the best settings for whatever environment that they're placed in.

So far two of the prototypes have been built, and we could use help building at least another 10.
To ensure that the 'bots go through the full range of their settings, random mutations will be introduced into their settings. Mutations that prove beneficial will spread through the swarm. The ones that don't will disappear within a few hours or days depending on how often they interact with their hivemates. This presented us with the first behavioral question we ran into before we'd even begun: Can the 'bots even exist individually? We didn't explicitly set out to design this behavioral aspect in, but a single 'bot might not be able to. It will still generate random mutations in it's code, but without at least one companion to compare it's efficiency with, it might get itself so far out of whack that the amount of power from sunlight it gathers during the day won't be sufficient for it to survive the night.
As for how the rest of the 'bots will spend the night, some members of the swarm may find themselves in a slightly better position than the rest. It may find it's way to a light that's been left on, or a bright spot beneath a window from a streetlight outside. If it manages to find one of these 'it's better than nothing' sources, it will remain in place and turn it's IR LED fully 'on'. This acts as a beacon for the rest of the members, who use the exact same light seeking script that they use to find sunlight during the day, except the brightest light it sees and steers towards is it's hivemate, and not the sun.
Once we get the 'bots built and programmed, we will wait and see how they act. Will they run about randomly during the day, or will they migrate from one side of the room to another following the sun's arc? Will they tend to roam alone, or will they travel in a pack? What happens when they reach a homeostasis with the environment we put them in? Will 'bots who have the same settings act exactly alike, or will individual traits arise? Will 'bots that live upstairs in the electronics area settle on the same settings as 'bots that live in the workshop, that gets no natural light at all? What happens if we introduce code that causes not just mutations in their settings, but also the code that they use to communicate with each other? We might wind up with two seperate subspecies that can't even communicate with each other. What happens if you mix them? Will one act as an invasive species, changing the settings of the natives, or will it's lack of ability to communicate doom it before it can learn the language of it's new hive? There's lots of questions to be answered...
So far two of the prototypes have been built (known as Frankie and Johnny) and are currently being put through their paces. A third prototype is also being constructed at this time.
