The Human Computer Interface consists of several separate modules, from which the system's operator controls and monitors all the movements of the robot. The iterface was designed so that the system's operator guides the moble robot, and monitors its progress, from any Web browser.

The main modules are:

    1. steering and maneuvering: control of speed and direction of the mobile robot

    2. video system control: control and display images from TV cameras either on board the robot or
        external

    3. navigation maps: 2D and 3D real time display of the mobile robot within the environment

    4. range data acquisition: interface to control the acquisition of range images with the laser range
        finder on board of the mobile robot

As in most applications, there is more data to be downloaded from robot (in particular video) than to be uploaded (commands).
