Give a poor robot a hand

Kacie Kinzer wanted to test human/robot interaction, so she invented the Tweenbots, little smiling robots capable of only trundling along in one direction. To get to their destination, advertised on a flag, they would need human help. Surprisingly, in several months of testing in New York all the robots completed their missions through the kindness of strangers.

It would be interesting to run this experiment in other cities and see if they are any less friendly than the Big Apple.
