Novel ball head screw and screwdriver design for implant-supported prostheses with angled channels: A finite element analysis
(2018-12-01)
Article
Open AccessThe primary objective of this study was to design the optimal geometry of a novel screwdriver, create the grooves on a ball head screw, and demonstrate its resistance to a torque of up to 40 Ncm at angulations of 0°, 15°, ... -
Link-based Performance Optimization of Spatial Mechanisms
(2014-12)
Article
Restricted access - publisher's policyIn the design of spatial linkages, the finite-position kinematics is fully specified by the position of the joint axes, i.e., a set of lines in space. However, most of the tasks have additional requirements regarding motion ... -
Dimensional Synthesis of Wristed Binary Hands
(2016-04)
Article
Open AccessThe kinematic synthesis applied to tree topologies is a tool for the design of multi-fingered robotic hands, for a simultaneous task of all fingertips. Even though traditionally wrists and hands have been designed separately, ... -
A Task-based Design Methodology for Robotic Exoskeletons
(Sage Publications, 2018-11)
Article
Open AccessThis study is aimed at developing a task-based methodology for the design of robotic exoskeletons. This is in contrast to prevailing research efforts, which attempt to mimic the human limb, where each human joint is given ... -
Mixed Position and Twist Space Synthesis of 3R Chains
(MDPI AG, 2022)
Article
Open AccessMixed-position kinematic synthesis is used to not only reach a certain number of precision positions, but also impose certain instantaneous motion conditions at those positions. In the traditional approach, one end-effector ... -
Design for the Automation of an AMBU Spur II Manual Respirator
(2021-02-21)
Article
Open AccessThis article shows the design of a device to automatize an Ambu Spur II manual respirator. The aim of this compassionate medicine device is to provide an emergency alternative to conventional electric respirators—which are ... -
New matrix methodology for algorithmic transparency in assembly line balancing using a genetic algorithm
(Elsevier, 2022-01-13)
Article
Open AccessThis article focuses on the Mixed-Model Assembly Line Balancing single-target problem of type 2 with single-sided linear assembly line configurations, which is common in the industrial environment of small and medium-sized ... -
Bennet's Linkage and the Cylindroid
(2002)
Article
Open AccessBennett’s linkage is a spatial 4R closed chain that can move with one degree of freedom. The set of relative displacement screws that form the one-dimensional workspace of this device defines a ruled surface known as a ... -
Underwater power generator based on gravity vortex siphon boost energy transition
(2021)
Article
Open AccessThe need for an energy transition is nowadays undeniable. Climate change, fossil fuel depletion and economic vulnerability are some of the main drivers of the model change. Therefore, it is necessary to promote local energy ... -
COVID-19 y la transición energética
(2020-05-05)
Article
Open AccessLa COVID-19 ha dejado en evidencia que nuestra vida cotidiana depende en una elevada proporción al acceso a la energía. Por tanto, ahora más nunca, es necesario potenciar las actividades de Km0 como la producción local de ... -
Residual vibration reduction in back-and-forth moving systems driven by slider-crank mechanisms working through a dead point configuration
(2021-01-13)
Article
Open AccessThis study proposes an algorithm to construct back-and-forth motion profiles to reduce residual vibrations of 1-dof linear oscillatory systems, driven through a transmission chain made up of a 1-dof linkage mechanism. This ... -
