Composable information unit 3D shape definition goes through single dimension abstraction definition

Let's assume code in Google is ready to produce informations to be transformed into a new java object, standardized for the application domain of the decision maker, via some interfaces ad hoc defined. These infos will be de-boxed and re-boxed into what has been previously defined compose-able information units. It is important to create a spatial 3D concetual shapes for the compose-able information units. This means that these units will be shapes, whose shape changes accordingly to their data content. Let's say a pojo whose value is an integer whose value is 3, will be a box, a pojo whose value is an integer whose value is 5 will be a sphere. This is very simplified, but could help in understanding as it really seems to me that human brain is more confident in approaching spatial problems. So: for this conceptual 3D shapes, how could be defined in term of software data representation, a single DIMENSION ? Every compose-able information unit will be threaded to become a virtual swarm belonging bee, able to link other bees. The behaviour of this swarm wil be translated into a system "expert" behaviour.

Last built hardware testing platform

These are some few shots of the hardware assembled to perform tests for a previous design of the same system. Motherboard is a pcm4823 by Advantech (c). CCD, frame grabbers, bump sensors, inclination sensors, two big legs.

Linux debian is on board, installed is also a GSM modem but it is not used yet. To provide minimum perimeter penetration events' notifications, there are Sharp GPD2D12 infrared barriers. Legs, when the system is used, are connected to the body one, per side. The motherboard (a POS like one) based on the industrial PC104 standard, for high level computation. Another board uquipped with a Motorola 68HC11 performs the readings from all sensors, makes all writing on all actuators. This board is quipped with a customized jvm created for this type of device. This board by Grifo implements the "man in the middle" design pattern.
It is possible to see details about the board and the java runtime at http://www.rtjcom.com/6811/gpc114.html. The motherboard is instead visible, here: http://taiwan.advantech.com.tw/support/sr_detail.asp?SR_ID=1%2BGE%2B1057. The problem is always the same, buy hardware after you know exactly the software requirements. Also when hardware is very interesting and an excuse is needed to have it, just because it has on board a 16MB disk on chip storage (DOC2000). A note on the "vision" system: the CCD was mounted inside a thermal insulation provided box with a Peltier cell just behind the bottom of the camera box. This because the intent was to keep cold the CCD and perceive infra red frequecies in few enlightened environments, making a bigger difference between the internal camera box temperature and the external world temperature. Simple pattern recognition was performed using PNG image files captured by a digital parallel port converter, connected to the analogue camera output.

This prototype name was "virgola", "comma" in English
