- Design and integration of a Lab-on-a-chip device for water pollution monitoring in an autonomous underwater vehicle(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2023) Naula Duchi, Edisson Andrés; Martínez López, José Israel; emimmayorquin; Chuck Hernández, Cristina Elizabeth; Gallo Villanueva, Roberto Carlos; School of Engineering and Sciences; Campus Monterrey; Garza Castañón, Luis EduardoConventional Autonomous Underwater Vehicles (AUVs) for seabed research and marine life studies are often limited by their noise emissions and disruptive appearance, hindering the ability to conduct non-intrusive underwater exploration. Additionally, the increasing costs of fuel and environmental concerns necessitate the development of more eco-friendly AUV designs. This thesis addresses these challenges by proposing a novel biomimetic AUV design inspired by the anatomy and swimming mechanics of tuna and dolphins. The proposed design incorporates a flexible body structure and undulating pectoral fins, enabling quieter and more efficient underwater propulsion. To evaluate the feasibility of the design, a prototype was constructed and subjected to numerical simulations, demonstrating promising results in terms of maneuverability and hydrodynamic performance. Furthermore, the thesis explores the integration of microdevice technology into AUVs for enhanced pollution monitoring capabilities. Microdevices offer a versatile and efficient platform for real-time data collection and analysis of water quality and pollutant levels. The challenges associated with integrating microdevices into AUVs, such as energy limitations, volume constraints, and time constraints, are also discussed. In addition to AUV propulsion and microdevice integration, the thesis presents a novel mixing characterization methodology for microfluid devices based on particle tracking. This methodology provides an alternative to traditional mixing evaluation methods and is implemented in a free and open-source mobile application (MIQUOD) for Android devices. The application utilizes concentration field data and particle track data to evaluate various mixing parameters. Finally, the thesis explores Stereolithography (SLA) as a manufacturing technique for creating customized underwater Point-of-Care (PoC) devices. SLA enables the fabrication of intricate features, such as engraved identifiers, inlet/outlet connections, and embedded electromechanical components, optimizing the spatial distribution and functionality of underwater vehicle components. A case study involving the design and manufacture of an array of micromixing-enhanced nitrite assay sensors demonstrates the potential of SLA for manufacturing customized underwater PoC devices.

- Mechanical Design and Assessment of a Biomimetic Upper-Limb Exoskeleton with Shoulder Mobility Enhancement(Instituto Tecnológico y de Estudios Superiores de Monterrey) Piña-Martínez, Eduardo; https://orcid.org/0000-0002-4730-6870; Rodriguez-Leal, Ernesto; Roberts, Ricardo; Gordillo Moscos, José Luis; Garza Castañón, Luis Eduardo; Soto Rodríguez, Rogelio; Campus Monterrey; Campus Monterrey; Campus MonterreyExoskeletons raise as the common ground between Robotics and Biomechanics, where rehabilitation is the main field in which these two disciplines find cohesion. Furthermore, the everlasting debate between the use of human labour or robotic machines could find a solution in these outstanding devices, which are intended to actuate in harmony with their wearers, maintaining the strength, precision, and accuracy commonly attributed to robots; and the dexterity, versatility, adaptability, and problem solving skills of human workers. To reach this point however, it becomes necessary to overcome the barriers that this robotic technology still has, such as the mechanical complexity that this devices demand. One of the most relevant challenges in upper-limb exoskeleton design relies in the high complexity of the human shoulder, where current devices implement elaborate systems only to emulate the drifting center of rotation of the shoulder joint. The main goal of this thesis project is to develop an upper limb exoskeleton mechanism, with the ability to allow complete movement of its wearer. This work proposes the use of 3D scanning vision technologies to ease the design process and its implementation on a variety of subjects, while a motion tracking system based on vision technologies is applied to assess the exoskeleton reachable workspace compared with an asymptomatic subject. Furthermore, the anatomic fitting index is proposed, which compares the anatomic workspace of the user with the exoskeleton workspace and provides insight into its features. This work proposes an exoskeleton architecture that considers the clavicle motion over the coronal plane whose workspace is determined by substituting the direct kinematics model with the dimensional parameters of the user. Simulations and numerical examples are used to validate the analytical results and to conciliate the experimental results provided by the vision tracking system. Moreover, this development is extended to the evaluation of the resulting prototype in tasks that depend on the users mobility freedom, where gross motion tracking was selected. The evaluation of this task is made by a real time comparison of the instrumented exoskeleton data and data obtained by a gross motion tracking commercial system, widely used in the state of the art developments and research works. Results from these design, development and assessment tasks show the proficiency of the proposed mechanism, reaching portability, mobility and lightness.
