Klok, J.W.A. (author), Postema, R.R. (author), Steintorsson, Astor T. (author), Dankelman, J. (author), Horeman, T. (author)In laparoscopic surgery, quality of haptic feedback is reduced compared to conventional surgery, leading to unintentional tissue damage during grasping. From the perspective of haptics, poor mechanical design of laparoscopic instrument joints induces friction and a nonlinear actuation-tip force relation. In this study, a novel laparoscopic...journal article 2023

Compliant Mechanisms That Use Static Balancing to Achieve Dramatically Different States of StiffnessKuppens, P.R. (author), Bessa, M.A. (author), Herder, J.L. (author), Hopkins, J. B. (author)Stiffness in compliant mechanisms can be dramatically altered and even eliminated entirely by using static balancing. This requires elastic energy to be inserted before operation, which is most often done with an additional device or preloading assembly. Adding such devices contrasts starkly with primary motivations for using compliant...journal article 2021

Radaelli, G. (author), Herder, J.L. (author)A new monolithic fully compliant gravity balancer is designed with help of a design approach based on shape optimization. The balancer consists of one single complex-shaped beam on which the weight is attached. The beam is modeled as a planar isogeometric Bernoulli beam. The goal function of the optimization consists of an energy based...conference paper 2015
