A Robot To Follow "Mother" And Another To Block Her

Wouldn't you like to be followed around by a mess of wires and boards whilst attempting to pass through a hallway guarded by another? Sounds like the ultimate in home security to me :-)."
An even more interesting robot is the one at CMU that walks around talking to people & showing facial expressions... these roboguard robots don't seem all that advanced, especially after seeing robot museum guides, nurses, and lots of other cool robots.
