Isaac Asimov coined the term robotic and he published three famous robotic laws :
• A robot can't damage a human being, nor allow this to be damaged.
• A robot must obey a human order, except when these orders clash with the first law.
• A robot must always protect themselves as long as this protection doesn’t clash with the first and second laws.

Work Space
It`s the space region composed by all the points that can be reached by the end of the arm o any point of the wrist, without taking the tool into account. The volume and the shape of the work space is very important for industrial applications, because they determine the robots capabilities.
