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.

Project Description

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.

The main features of the CONTROLAB AGV are:

It's a tricycle carlike AGV;
It's follows orders issued by client stations connected to the internet;
It's Global navigation function demands very low computational load and can be used to avoid any kind of obstacle;
It requires low cost sensors.
