Query: An experimental mechatronic design and control of a 5 DOF Robotic arm
  for identification and sorting of different sized objects   The purpose of this paper is to present the construction and programming of a
five degrees of freedom robotic arm which interacts with an infrared sensor for
the identification and sorting of different sized objects. The main axis of the
construction design will be up to the three main branches of science that make
up the Mechatronics: Mechanical Engineering, Electronic-Electrical Engineering
and Computer Engineering. The methods that have been used for the construction
are presented as well as the methods for the programming of the arm in
cooperation with the sensor. The aim is to present the manual and automatic
control of the arm for the recognition and the installation of the objects
through a simple (in operation) and low in cost sensor like the one that was
used by this paper. Furthermore, this paper presents the significance of this
robotic arm design and its further applications in contemporary industrial
forms of production.
