Of people and robots

Alter Rebbe says in Tanya that for the most part people do not help other people selflessly (they do it to feel better about themselves, to get something out of it, etc. — which is why it says in Gemara that “kindness of nations is sin”). What about helping small wooden 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.
