If you're curious about adding security to your wireless home network, check out our new security slide show, where I've posted some simple procedures such as changing the default password to your router, changing your SSID, adding WEP or WPA encryption, and, finally, whether you want to filter by MAC address devices (laptops, mobiles, and so forth) that have access your network. In this example I use a Linksys Wireless-G WRT54GS router plugged into a Dell XPS 600 desktop running Windows XP, but the basic steps can be modified for other routers and other Windows operating systems.
Is this a real RoboCop?
The K5 robot, developed by Sunnyvale, Calif.-based Knightscope, is designed to be a surveillance robot for law enforcement, private security firms, schools and anything else looking for an extra set of eyes and ears on the ground. The 5-foot, 300-pound robot can roam autonomously, sending back real time data about an area with technology that does facial recognition, lidar mapping and 360-degree video. CNET's Kara Tsuboi got a closer look at what makes the K5 robot tick.
