Abstract: A robot for performing substantially autonomous movement includes a processing device, a memory, and a mobility structure controlled by the processing device. The processor directs the robot to move with any predetermined safe area having a boundary and a reference point. Optionally, the robot also exhibits features of social interactivity by accepting an input from a human, selecting dynamic content from a data base wherein the dynamic content is responsive to the input, and presenting the human with a response corresponding to the dynamic content selection.
