What works better: hard, cold technology or arcane, mystical powers? We put that question to a test by seeing which would better help us get home, a Magic 8 Ball or the GPS navigation system in a Honda Accord. We made our start point in the midst of suburban streets near Tiburon, and tried each method to direct us back across the Golden Gate Bridge, into San Francisco. With the Magic 8 Ball, we asked it at each intersection whether we should go right. Using the GPS navigation system, we merely input the address in San Francisco where we wanted to go. The results, as they say, will surprise you. Or maybe not so much.

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.
