Robots are certainly convenient
but they won't replace human beings, I think.
Imagine you are in a disaster-attacked area.
If you have to find a person from a collapsed house, you should use a robot.
But, if you have to care for mentally or physically damaged people, you should not utilize them.
To sum up, they have both advantages and disadvantages. So, they're used on the scene, which are high-risked for human health or life.
