Abstract

fetched live from OpenAlex

El objetivo de la presente investigación es diseñar y construir un prototipo funcional del dedo índice para una prótesis mioeléctrica de miembro superior, la cual será utilizada por un habitante del municipio de Barbosa Santander. La función principal es dotar de movimientos, como lo son extender y contraer el dedo índice de una prótesis para amputación transradial. En cuanto a la ejecución, se utilizan las cinco fases de desarrollo de diseño fiNASA ESMD Capstone Design Processfl. En primera instancia se identificaron las necesidades del paciente tales como: funcionabilidad, costos, estética, confiablidad y comodidad, lo cual permitió determinar los factores de diseño y el planteamiento de la mejor alternativa. El desarrollo de esta propuesta consistió en diseñar y construir tres mecanismos de cuatro barras ensamblados en un conjunto conocido como mecanismo de Toronto (MT), el cual permitió dimensionar y articular las tres falanges. Así mismo, el accionamiento del MT se realizó mediante la adquisición y procesamiento de las señales electromiográficas, que permite enviar una orden al microcontrolador para que gire 150° o regrese a su posición inicial (0°) y a su vez, mediante dos cables Bowden accione el MT, para generar el movimiento deseado. Lo anterior llevó a concluir que al utilizar diferentes procesos de fabricación (como impresión 3D, corte manual, taladrado, pulido y doblado), se brinda la precisión requerida a un menor costo. Por lo tanto, se aplicó la prueba funcional al paciente y los resultados, mostraron que el prototipo es aceptable ante los requerimientos planteados.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
