The proposed software framework is presented and an Application Programming Interface (API) is developed based on the Arduino Mega 2560. The API processes external commands that follow the operational logic of a gel electrophoresis device. The API acts as an intermediary layer between the gel electrophoresis mechatronic system’s microcontroller and the motors’ controllers. The microcontroller enables the basic functionalities of the gel electrophoresis system while the use of 2 axis (X, Z) motor controllers is necessary for controlling the moving parts of the mechatronic system. We control the movement’s direction, position, speed, and acceleration. The developed API controls the stepper motors drive axles and the DC motors for opening and closing the drawers and other moving parts of the mechatronic system.

The paper present the methodology to design and implement a mechatronic system for gel electrophoresis. It describes the steps towards the development of a prototype and presents its functions. The new automated system is characterized by high precision, small size and relatively low cost, thus achieving the introduction of a significant innovation in the area of medical and laboratory measurements.

A method is presented, by which a Finite Element Method (FEM) formulation is used for the direct computation of overhead transmission line series and sequence impedances. The method is applied in single and double circuit line configurations of arbitrary geometry, giving results in perfect agreement with those available from classical calculation methods. The new method can easily handle cases of nonhomogenous and/or irregular terrain, where classical methods may fail.
