It's fascinating how we anthropomorphize objects like this. My Roomba got stuck on some cables underneath my TV table and when I found it, it was making a sad sound that just broke my heart. As I picked it up, I found myself saying, "There, there little Roomba, I'll rescue you and get you some juice. Poor thing."
In general, unless you are a sociopath with no empathy, humans have an innate need to help and assists others. It makes us feel good to help others, not just our own children.
