A new methodology for designing PD controllers [PDF]
, 2001 It is known that it is impossible to select fixed gains for a PD controller that will critically damp the response to disturbances for all configurations of a given robot system. Because of this the potential for overshoot is always present and cannot be

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 ...
