Command Center

The command center runs on a Windows 95 or better operating system
PC that is connected to the wireless network through a Network
Everywhere Cable/DSL Router. It has a Video Capture Card connected
to an X10 wireless video receiver.
From the command center, users can control PDA Robot remotely. It
can detect motion, as well as save and send images via file transfer
protocol (FTP) or simple mail transfer protocol (SMTP). When the
application starts, it listens for a connection from the PDA that is con-
trolling PDA Robot. When PDA Robot successfully logs in, users can
begin controlling the craft remotely, looking through its eyes. Figure
10.1 shows the main screen of the command center.
