A series of tests were performed, both locally and remotely, to check the performance of the whole system. Some test conditions are:

    * the update of the robot, pan & tilt, ultrasound, and mobile video camera state on the web server computer is performed from the host server every 1100 milliseconds

    *the update of the robot, pan & tilt and ultrasound sensors state on the client computer is performed from the Java server every 700 milliseconds

    *the images from the two video cameras are updated every second

    *the location of the robot was consistent for all tests (ie, testing done in same room)

    *the web browser used was NetScape 4.05 with CosmoPlayer 2.0 and RealVideo 5.0 as plug-in
