In the following videos, a client connects to the Orders Server,
issues an order and then watches the AGV's trajectory. The Orders Server
communicates with the AGV through radio transceiver. Note that the two videos,
although separated, were recorded simultaneously.

The CONTROLAB AGV is an electric tricycle vehicle. It moves autonomously within office
environment and follows instructions issued by any station connected to the
internet. The Tele-commanded Autonomous Guided Vehicle is equipped with a radio transceiver, hardware/software resources for storing and processing information
and an "electronic stick" consisting of infrared sensors for
detecting unknown obstacles. The AGV uses a similar strategy adopted by a blind
person to avoid obstacles when walking. Initially, it moves following a global
Potential Field defined by the floor plan. While the AGV is moving, the original
field is modified each time the stick detects an obstacle. These adaptations are
performed by
simply adding two previously calculated potential
field values on a grid, the field due to the floorplan and the potential field
associated with the single point reached by the stick. The computational effort for this adaptation is very low
and, as a consequence, it is performed in real
time.
