Kinematic Analysis of a Continuum Parallel Robot
Altuzarra Maestre, Oscar; ; ; ; (Springer, 2017)
Continuum Parallel Robots are mechanical devices with closed loops where kinematic pairs have been eliminated and motion is obtained by large deformations of certain elements. Most compliant mechanisms use notches in thick ... -
Kinematic Analysis of a Flexible Tensegrity Robot
Altuzarra Maestre, Oscar; ; ; Campa Gómez, Francisco Javier (Springer, 2017)
In the field of parallel kinematics few designs use highly deformable elements to obtain the end effector movement. Most compliant mechanisms rely on notches or shape changes to simulate a standard kinematic joint. In this ... -
Kinematic Analysis of a Tendon-Driven Hybrid Rigid–Flexible Four-Bar; Application to Optimum Dimensional Synthesis
Hernández Frías, Alfonso; ; Urízar Arana, Mónica ; Altuzarra Maestre, Oscar (MDPI, 2023-10-09)
In design matters, mechanisms with deformable elements are a step behind those with rigid bars, particularly if dimensional synthesis is considered a fundamental part of mechanism design. For the purposes of this work, a ... -
Kinematic Analysis of three degrees of freedom planar parallel continuum mechanisms
Altuzarra Maestre, Oscar; Urízar Arana, Mónica ; ; Petuya Arcocha, Víctor (Elsevier, 2023-07)
Parallel continuum mechanisms are a type of compliant mechanisms comprising a rigid end-effector connected to a fixed frame by flexible and slender elements in a closed-kinematic morphology, being their flexibility the ... -
Kinematic and Kinetic Analyses of the Vertical Jump with and without Header as Performed by Para-Footballers with Cerebral Palsy
; ; ; ; Yanci Irigoyen, Javier (MDPI, 2019-09-12)
Vertical jump is a relevant variable in the classification of football for individuals with cerebral palsy. In this regard, the literature is limited. There are no studies assessing vertical jumping ability through kinematic ... -
Kinematic and Neuromuscular Measures of Intensity During Drop Jumps in Female Volleyball Players
Torres Banduc, Maximiliano; Ramírez Campillo, Rodrigo; Andrade, David Cristóbal; Calleja González, Julio María; Nikolaidis, Pantelis Theo; McMahon, John J.; Comfort, Paul (Frontiers Media, 2021-09-20)
The aim of this study was to assess drop jump (DJ) performance variables (jump height, contact time, and reactive strength index) concomitant to surface electromyography (sEMG) of lower limb muscles during DJs from different ... -
Kinematical and dynamical modelling of a multipurpose upper limbs rehabilitation robot
; Zubizarreta Pico, Asier; ; ; (Elsevier, 2017-08-23)
Knowing accurate model of a system is always beneficial to design a robust and safe control while allowing reduction of sensors-related cost as the system outputs are predictable using the model. In this context, this paper ... -
Kinetic Model for the Direct Conversion of CO2/CO into Light Olefins over an In2O3–ZrO2/SAPO-34 Tandem Catalyst
; ; Aguayo Urquijo, Andrés Tomás; ; ; (ACS, 2024-01)
An original kinetic model is proposed for the direct production of light olefins by hydrogenation of CO2/CO (COx) mixtures over an In2O3–ZrO2/SAPO-34 tandem catalyst, quantifying deactivation by coke. The reaction network ... -
Kinetic modeling and reactor design of the direct synthesis of dimethyl ether for CO2 valorization. A review
; ; ; Aguayo Urquijo, Andrés Tomás; (Elsevier, 2022-08-04)
The direct synthesis of dimethyl ether (DME) is considered one of the most attractive routes for valorizing CO2 and syngas on a large scale. DME has a high cetane number and its properties are similar to those of liquefied ... -
