Details of Baby-bot

In the laboratories of the Lira-lab of the University of Genoa it has been put to point Babybot, a small robot to the vanguard if compared to created concurrent its to the Medialab of the MIT of Boston or in the centers of search of the Sony. The plan has been financed from the European Union.

The structure of Babybot is composed from various mechanical organs that allow it to move with disinvoltura are to right that on the left. The support base is constituted from a small cylinder. But its peculiarity - it explains Giulio Sandini, director and ideatore of the Lira-lab, - is the eyes crafts them that they produce an identical resolution to that one of most modern blots some photographic digita them, from the three to four the million pixel.

The investigators of the Lira-lab are themselves base to you on the natural mechanisms of the human hairnet in order to put to point the visual apparatus of Baby-bot. The dimensions of the receptive fields of the neurons in the human hairnet increase with the distance from the center of the image (fovea). The information in escape comes codified gives approximately a million receptive fields. Geometry of the hairnet offers to ineguagliabili advantages for the determination of the trajectory, the position and the positioning of the objects. Pack-saddles to remember that if the hairnet were structured like a camera digita them in which the pixel they were structured equally with a uniform distribution, in order to transmit all necessary the visual data to the visual ability to the eye would serve an optical nerve with a diameter of some centimeters.

The visual apparatus of Baby-bot is riconducibile to the retinal structure. In fact, the investigators are resolutions to put to point of the eyes that gives the possibility to the robot to seize, as an example, with the mechanical arm, an object launch towards of he. A performance much complex that Baby-bot can make with disinvoltura thanks a substantial reorganization of the data to elaborate with a consequent simplification of the calculation algorithms.

The technique put into effect from the investigators of the Lira-lab of the University of Genoa is currently the only one to being in a position to also sending "complete" images on bands of transmission like those of telefonini GSM or GPRS. To this point it is easy to intuire that the technology could be applied for the construction of dispositi you of communication for not hearing subjects. In fact, cellular apparatuses equip you of display and microvideo camera could concur a communication to high resolution spaces centers them them that the reading of the labbra would concur of who speaks, while the resolution, even if not elevated, to also distinguish the movements of the arms and the hands picking up the expressions makes them.
