This article presents the design of a newly developed 2DoF robotic arm with a novel statically balanced and bi-stable compliant grasper as the end effector for laparoscopic surgery application. The arm is based on internal motors actuating 2 rotational DoFs: pitch and roll. The positive stiffness of the monolithic grasper has been compensated...

Micro-electromechanical system (MEMS) comprising a substrate or substrate parts, and a compliant first segment or segments within the substrate or substrate parts with a predefined positive stiffness, wherein the first segment or segments is or are statically balanced. This is embodied by applying a second segment or segments within the...

A novel compliant Magnetic Levitation System (MLS) for a wired miniature surgical camera robot was designed, modeled and fabricated. The robot is composed of two main parts, head and tail, linked by a compliant beam. The tail module embeds two magnets for anchoring and manual rough translation. The head module incorporates two motorized donut...

For many applications in precision engineering, a six degrees of freedom (DoF) compliant stage (CS) with zero stiffness is desirable, to deal with problems like backlash, friction, lubrication, and at the same time, reduce the actuation force. To this end, the compliant stage (also known as compliant mechanism) can be statically balanced with a...

Yet another journal? And what is the windmill about? Those are two questions that we heard a lot lately. Yes, another journal, or rather, a different journal, called Mechanical Sciences (MS). The main difference is that the journal is open access, of which there are not many in the field of mechanical sciences. Grant agencies more and more...

The deflection of compliant mechanism (CM) which involves geometrical nonlinearity due to large deflection of members continues to be an interesting problem in mechanical systems. This paper deals with an analytical investigation of large deflections in compliant mechanisms. The main objective is to propose a convenient method of solution for...
