I stumbled across this site quite accidentally. It’s about an experiment with cute little robots that are fairly helpless and seeing what happened when they relied on the kindness of strangers to get where they were supposed to go.
The creator of the experiment made the robots as cheaply as possible — expecting them to meet their doom in the cruel, cruel world — but was pleased to find that even in New York city there were strangers who were willing to help a little defenseless robot.
