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.
Given their extreme vulnerability, the vastness of city space, the dangers posed by traffic, suspicion of terrorism, and the possibility that no one would be interested in helping a lost little robot, I initially conceived the Tweenbots as disposable creatures which were more likely to struggle and die in the city than to reach their destination…
The results were unexpected. Over the course of the following months, throughout numerous missions, the Tweenbots were successful in rolling from their start point to their far-away destination assisted only by strangers.
My favorite bit:
One man turned the robot back in the direction from which it had just come, saying out loud to the Tweenbot, “You can’t go that way, it’s toward the road.”
I hope that guy’s having a great day. He earned it with that little bit of altruism. (Ditto Kacie Kinzer, creator of the Tweenbot experiment.)
