Design of an automated system for the production of chicha de Jora

This research presents the design and control of the fermentation, boiling, and straining process of chicha de Jora with mechatronic systems. In this work, process control is developed in the 2 tanks to monitor the procedure to optimize the resources and time of the elaboration. The development of the project shows that the application of 2 solenoid valves and sensors such as level and temperature sensors are feasible for better control of the boiling process. A mixer was also added to the first tank to ensure that the essence of the inputs remains in the liquid. In addition, it is possible to visualize an optimal operation of the system, including PLC programming as it makes the operation more autonomous, managing to accelerate the fermentation process and to be adequate according to the degree of alcohol required. The value obtained from the motor to drive the 6-blade mixer is 17,384 watts taking as a parameter the viscosity, the power number, and the appropriate rotation speed. The implemented control will help to accelerate the process of obtaining chicha de Jora and to monitor the degree of alcohol produced in the fermentation process

Design of haptic vibrational feedback control in upper extremity myoelectric prostheses

Current prosthesis systems use haptic technology, have a brain-machine interaction that is dependent on visual feedback from the user, also have limitations by the details of the sense of touch both textures, roughness, weights, and contact forces applied. This research shows the development and implementation of haptic technology in a myoelectric prosthesis of the upper extremity, to simulate the sense of touch in the claw of the prosthesis to obtain a better control in the grip force taking as parameter the reaction and efficiency that the device has in different conditions for the patient to have an improvement in the feedback and the grip force of the prosthesis. For the development of the investigation, the VDI2206 methodology was used, simulating each part of the myoelectric prosthesis in different software for an improvement in the process of signal interpretation. Also by diagramming the motor execution process it facilitates the interpretation of the design. The results of the investigation show an alternative model of the conventional ones contributing with improvements in the signals received by the haptic prosthesis and better ergonomics, in addition, the perceived signals showed a better subjection and sensitivity. From the presented design it is desired to replicate to future research since the presented model can be taken as research material
