Activities during this project were: development process instrumentation basic flowcharts, architecture design and strategies for the control system and preparation of technical and financial proposals for the development of a Master Plan Automation

A graphical interface, through the National Instruments LabView software, allowing to program, control and monitoring of the movements made by the robot arm RV-M1 of the Mitsubishi brand, employing the default by the command processor was designed robot in order to draw this three geometric shapes (circle, square and triangle) with a marker on a paper surface.

A control system level two tanks, involving sensors presence and level using the RSLogix 5000 software to implement the ladder was designed. Also, an interface was implemented in Factory Talk View Rockwell Automation to monitor and modify the process, according to parameters specified by the user

A system for the detection and color reproduction, using the detection diodes and infrared emitters and receivers designed for reproduction theory RGB (Red / Green / Blue) and LEDs interconnected and controlled by the Altera Cyclone II FPGA scheduled by the Quartus II language.

An electromechanical scale is designed to make the diagnosis of body weight of a user whose worth their weight was located within the range of 40-100 kg. For this design concepts area in direct current circuits connecting employed strain gauges were used for the transduction of the weight force into an electrical signal which may be compared with that recorded for the weight signal measured for the first user and evaluated over a range of ± 3kg.
