- Three-dimensional bioprinter based on a robotic manipulator for the development of arbitrarily shaped scaffolds for tissue engineering applications(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-12) Ayala Roldán, Diana Paola; Chairez Orta, Jorge Isaac; emipsanchez; Alfaro Ponce, Mariel; Navarro Gutiérrez, Manuel; Flores Jiménez, Mariana Sofía; School of Engineering and Sciences; Campus Ciudad de México; Hernández Sánchez, AlejandraThis thesis details the development of a robotic manipulator-based bioprinting system designed to fabricate scaffolds with complex geometries for tissue engineering applications. Incorporating a fivedegree- of-freedom manipulator, the platform addresses limitations of conventional methods, enabling precise and adaptable fabrication. Key technological achievements include: • A robotic manipulator, powered by high-precision servo motors, provides spatial flexibility essential for complex, patient-specific configurations. This expanded range enhances geometries, better mimicking natural tissue structures. • A computer vision system for real-time adjustments, maintaining alignment with the intended design by dynamically tracking the end effector’s position and orientation. This reduces deviations, ensuring high geometric fidelity and structural consistency. • An extrusion mechanism capable of handling bioink with diverse rheological properties, supporting intricate architectures. This flexibility accommodates a broad range of viscosities and structural characteristics. • A control and feedback system that integrates a proportional-integral-derivative (PID) mechanism, stabilizing the robotic arm’s trajectory. This real-time feedback loop enhances positional accuracy, preserving scaffold integrity under varying conditions. This platform exemplifies advancements in fabrication flexibility, precision, and customization, supporting scalable, patient-specific applications in regenerative medicine.
- Design, simulation and construction of a lineal induction motor for a transport application(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-06-15) Campoy Sousa, Angel Rodrigo; VAZQUEZ TOPETE, CARLOS RENATO; 166163; Vázquez Topete, Carlos Renato; emipsanchez; Carbajal Espinosa, Oscar Eleno; Guajardo Cuellar, Alejandro; Escuela de Ingeniería y Ciencias; Campus MonterreyThe high levels of traffic increase both the noise and air pollution in the city of Guadalajara. These affects drivers, passengers and pedestrians. The problems involved due to the current mobility system in the city motivates the research of new types of urban transport, preferably a low cost electric vehicle. An interesting option to investigate are linear induction motors (LIM), which have a low number of parts, low maintenance and low cost. In order to design a LIM, the literature about Linear Motor Design was studied in detail, specially the Equivalent Circuit Model. The model allows to dynamically simulate a LIM according to its geometrical and electrical supply specifications. In this thesis it is proposed to design, simulate and build a prototype to compare the real behavior and the results of the simulation. The vehicle should be designed to have a low cost of manufacture, have a capacity of 5-6 passengers, an average speed of 25 km/hr and a road inclination of 1.15 degrees.
