Engineer’s Day is dedicated to those without whom every machine would not be made. Engineers apply techniques of engineering analysis in testing, production, or maintenance.
An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics, and ingenuity to develop solutions for technical, societal and commercial problems. Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer is derived from the Latin words ingeniare (“to contrive, devise”) and ingenium (“cleverness”).

ABSTRACT: A human-robot interactive system in which a robot and a human share an area for performing interactive work, the human-robot interactive system including a force sensor which is set at an end effector attached to a front end of the robot or which is set at the robot and, when a detected value of the force sensor exceeds a predetermined value, is configured to stop the robot or controlling operation of the robot so that a detected value of the force sensor becomes smaller, the system further including a limiter which limits a work area of said human so as to prevent contact by the human with the first robot portion of the robot that is positioned further from the human than a set position of the force sensor during operation even when the robot approaches the human.
