One of the main things that make humans not comfortable while dealing with robots, or are not accepting that there is a possibility that one day humans might have a relationship with a robots is that robots have a mechanical inner structure. Robots are unlike humans they do not have blood, veins, muscles and so on, as we all know. Thus, this makes humans uncomfortable when they are dealing with them, so robots’ manufacturing companies have managed to develop a robot, called the Anthropometric robot that has an inner structure similar to humans. They managed to make its inner structure containing muscle, joints and tendons so it could act and interact like humans, and for humans to be more comfortable while dealing with it. Moreover, the added the facial recognition software to the robot to be able to act and interact exactly like humans.
Here is a picture of an anthropometric robot.
