Egg

Let’s assume that you were a bird just born inside an egg. Are you sure that you could imagine the world outside the egg? No! You may not even recognize the fact that there is a barrier between the world and you. The concept of barrier is not formulated until the subsequent existence of the outside world . Thus, you cannot imagine or postulate the existence of an egg since it does not show you any information about the outside world. The existence is the farthest enclosure of your world. At this point, your existence itself is to impose a constraint on yourself. You have a freed mind. However, your mind always conceives the unreachable world that you are not able to imagine. In this work, a small mirror continuously follows up and blocks your hand creating an invisible wall. At this moment, look at the hand blocked and reflected by the mirror. Ask yourself, which object is blocking you? Is it the wall created by a complex robotic device or just yourself?

Technical implementation:
The robot was constructed from six servomotors. The end effectors of the arm can make six degrees of freedom motion in space. A depth-sensing camera is installed above the robot to watch and find the closest point of the object that is in front of it. Using this information, the robot arm is able to block any object by creating a virtual wall with a mirror.
