We were busy having dinner with my nephew and his friends when I looked outside the window and saw this robot pacing up and down the street. Totally cool!

Of course, a few of us rushed out to check it out. The robot would walk up to strangers, and if you extended your hand, it would clasp it between its palms to greet you. And then take leave and amble away!

BTW, the three that rushed out of our party of six? They were the only Computer Science majors (current and long past) at the table.
