A New Performance Index for Underactuated Cable-Driven Parallel Robots [PDF]
, 2021 Cable-driven parallel robots (CDPRs) equipped with less cables than the end-effector (EE) degrees of freedom (DoFs) are underactued and underconstrained by design. These characteristics imply that only a subset of the EE DoFs can be assigned for planning

Laparoscopy & robotics: a historical parallel [PDF]
Revista do Colégio Brasileiro de Cirurgiões, 2020 ABSTRACT The evolution of robotic platforms has brought up ethical, economic, educational, and clinical applicability issues that refer to the early 1990s, when laparoscopy began its dissemination as a technology that would revolutionize surgery. Introduced in Brazil since 1990, laparoscopy has received a lot of resistance from different sectors ...
