If we can believe anything we saw at CES, it’s going to be a great year for getting directions in shopping malls.

Information robots took over the robot section of the show floor this year, signalling that the technology to scoot around and act as guides will become as commonplace as the droids in Star Wars that scurry about the ankles of humans, performing simple tasks. More realistically, there’s no discernable difference between these robots and an iPad on a stand in the middle of a store lobby.
