Tweenbots

Here's an interesting experiment:

Tweenbots are human-dependent robots that navigate the city with the help of pedestrians they encounter. Rolling at a constant speed, in a straight line, Tweenbots have a destination displayed on a flag, and rely on people they meet to read this flag and to aim them in the right direction to reach their goal.

The results were insightful: the tiny robots successfully reached their destination through the help of complete strangers. No robot was lost nor damaged.

I wonder how the Tweenbots would fare in, say, Quiapo or Cubao, or Rizal Park even.
