minutes the time needed to complete the removal of a given brick, no appreciable dead time is expected
for the experiment.
Another possible system for brick handling, whose design has been carried out in collaboration with
industry, 9 is described in Fig. 40 and 41.
Figure 40: Brick manipulator system employing a self-propelled vehicle.
The envisaged solution consists of a manipulator with two axes of movement (horizontal and vertical)
located on one side of the target. The horizontal stroke for the accurate insertion of the bricks on the
tray is given by a small self-propelled vehicle (little car) which moves on the tray which constitute the
brick shelf. The vehicle is fed by a belt conveyor (shuttle), on which the bricks accurately oriented are
laid. The shuttle is located at floor level and is moved vertically by a single track conveyor. At least two
shuttles are used, so that a shuttle is feeding the vehicle while another is (e.g. manually) loaded.
The two axes manipulator is composed of an upper track with a rack for the longitudinal stroke (as
long as the three supermodules) to which the trolley is hung on which is bound the vertical axis. In
the lower part there is a track to avoid oscillations of the manipulator around the horizontal axis. The
vertical axis is made of a linear unit with meshed belt and a geared motor assembled in a high position,
