Robotics is one of the branches of engineering that will play a very important role in the Industry 4.0 scheme. One way for Higher Education Institutions to have robotic devices without incurring high costs is through self-equipment. This paper presents the design and construction of the mechanical structure of a robotic arm type SCARA for teaching applications. The prototype has 3 degrees of freedom and a maximum operating radius of 35 cm. Using a suction cup, it is possible to move objects with a maximum weight of 200 grams. Arm movements are performed by stepper motors. Each degree of freedom has associated limit switches that will serve to limit the movements of the robotic arm when controlling its operation. Preliminary tests of operation show that the movements of the system are correct and are within the established values for the equipment.

Automation training in engineering schools requires laboratories equipped in order to complement theoretical courses and develop students' ability to solve practical problems. The high cost of educational models makes access to these equipment difficult. The development of an academic mechatronic system with two degrees of freedom for Pick-and-Place tasks is presented. The device can hold objects up to 200 gr and move them in a plane XZ. The object is held by a vacuum system. On the horizontal axis the displacement range is 45 cm and on the vertical axis 10 cm. The prototype has a connection board where the sensors and actuators signals are available. This allows students to control the device through different technologies. These signals are also available on an-Ethernet port to expand the communication capacity of the device. Preliminary tests show the correct functioning of the mechanical and electronic systems developed.
