Transición entre tipos de locomoción de un robot cuadrúpedo articulado
(Medellín - Minas - Doctorado en Ingeniería - SistemasUniversidad Nacional de Colombia - Sede Medellín, 2019-07-15)
The present work is an investigation of the transitions between types of locomotion using central pattern generators in quadruped robots with three joints per leg. Also, central pattern generators are created with systems ...
Magnesium-based bioresorbable cellular metal as bone substitute
(Universidad Nacional de Colombia - Sede MedellínMedellín - Minas - Doctorado en Ingeniería - Ingeniería Mecánica y MecatrónicaDepartamento de Ingeniería MecánicaFacultad de MinasMedellínUniversidad Nacional de Colombia - Sede Medellín, 2021)
The design and development of an osteoinductive environment to reconstruct and treat large bone defects is still a challenge. Biodegradable porous metals have been proposed to bridge healthy parts of the tissue when the ...
