A gripper for delicate edible manipulation
Cardin-Catalan, Daniel; Morales, Antonio; Llop-Harillo, Immaculada; Pérez-González, Antonio; del Pobil, Angel P. Elsevier (2023-09-25)The general manipulation of delicate edible products requires of specific grippers able to firmly grasp these kind of products without damaging them. To address this problem we follow a soft and variable-stiffness approach. ... -
Affordable 3D-printed tendon prosthetic hands: Expectations and benchmarking questioned
Andres-Esperanza, Javier; Iserte-Vilar, Jose L.; Llop-Harillo, Immaculada; Pérez-González, Antonio Elsevier (2021-09-10)The popularization of 3D-printing has allowed enhancing affordable prostheses for persons with amputations in developing countries, yet manufacturers are not subjected to any control from any medical regulatory authority. ... -
Anthropomorphism Index of Mobility for Artificial Hands
Llop-Harillo, Immaculada; Pérez-González, Antonio; Gracia-Ibáñez, Verónica Hindawi (2019-07-28)The increasing development of anthropomorphic artificial hands makes necessary quick metrics that analyze their anthropomorphism. In this study, a human grasp experiment on the most important grasp types was undertaken in ... -
Anthropomorphism Indexes of the Kinematic Chain for Artificial Hands
Llop-Harillo, Immaculada; Pérez-González, Antonio; Andres-Esperanza, Javier Springer (2020-05-23)Anthropomorphic hands have received increasing research interest in the fields of robotics and prosthetics. But it is not yet clear how to evaluate their anthropomorphism. Similarity in the kinematic chain is essential to ... -
Benchmarking anthropomorphic hands through grasping simulations
Llop-Harillo, Immaculada; Iserte, José Luis; Pérez-González, Antonio Oxford University Press (2022-02-25)In recent decades, the design of anthropomorphic hands has been developed greatly improving both cosmesis and functionality. Experimentation, simulation, and combined approaches have been used in the literature to assess ... -
Effect of the Thumb Orientation and Actuation on the Functionality and Performance of Affordable Prosthetic Hands: Obtaining Design Criteria
Andres-Esperanza, Javier; Iserte-Vilar, Jose L.; Llop-Harillo, Immaculada; Pérez-González, Antonio Biomimetics (2022-12)The advent of 3D printing technologies has enabled the development of low-cost prosthetic underactuated hands, with cables working as tendons for flexion. Despite the particular relevance to human grasp, its conception in ... -
Grasping Ability and Motion Synergies in Affordable Tendon-Driven Prosthetic Hands Controlled by Able-Bodied Subjects
Llop-Harillo, Immaculada; Pérez-González, Antonio; Andres-Esperanza, Javier Frontiers Media (2020-08-26)Affordable 3D-printed tendon-driven prosthetic hands are a rising trend because of their availability and easy customization. Nevertheless, comparative studies about the functionality of this kind of prostheses are ... -
Identifying Users’ Needs to Design and Manufacture 3D-Printed Upper Limb Sockets: A Survey-Based Study
Roda-Sales, Alba; Llop-Harillo, Immaculada MDPI (2024)The development of prosthetic arms has increased in recent years, particularly with the growth of 3D printing technologies. However, one of the main weaknesses of 3D-printed prosthetics is the prosthetic socket, which ... -
System for the experimental evaluation of anthropomorphic hands. Application to a new 3D-printed prosthetic hand prototype
Llop-Harillo, Immaculada; Pérez-González, Antonio Taylor & Francis (2017)In the present study, we propose a new actuation device and protocol for testing the grasping performance of low-cost 3D-printed hand prototypes. The actuation device is connected to the forearm of a healthy user and allows ... -
The Anthropomorphic Hand Assessment Protocol (AHAP)
Llop-Harillo, Immaculada; Pérez-González, Antonio; Starke, Julia; Asfour, Tamim Elsevier (2019-11)The progress in the development of anthropomorphic hands for robotic and prosthetic applications has not been followed by a parallel development of objective methods to evaluate their performance. The need for benchmarking ...
