I found this story interesting. What is it about humanity that we gladly help a cardboard robot along its way, but are seemingly unable to stop waging war on each other. Of course, this may simply display the diversity among humanity, but I found this story intriguing and "cute" nonetheless.Kacie Kinzer
In New York, we are very occupied with getting from one place to another. I wondered: could a human-like object traverse sidewalks and streets along with us, and in so doing, create a narrative about our relationship to space and our willingness to interact with what we find in it? More importantly, how could our actions be seen within a larger context of human connection that emerges from the complexity of the city itself? To answer these questions, I built robots.
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.
Because I built them with minimal technology, I had no way of tracking the Tweenbot’s progress, and so I set out on the first test with a video camera hidden in my purse. I placed the Tweenbot down on the sidewalk, and walked far enough away that I would not be observed as the Tweenbot––a smiling 10-inch tall cardboard missionary––bumped along towards his inevitable fate. 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.
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.
