In high precision equipment the use of compliant mechanisms is favourable as elastic joints offer the advantages of low friction and no backlash. To satisfy exact constraint design the mechanism should have exactly the required degrees of freedom and constraints so that the system is kinematically and statically determinate. For this purpose we propose the following kinematic analysis using a f...

Mutable collagenous tissues (MCTs) of echinoderms show reversible changes in tensile properties (mutability) that are initiated and modulated by the nervous system via the activities of cells known as juxtaligamental cells. The molecular mechanism underpinning this mechanical adaptability has still to be elucidated. Adaptable connective tissues are also present in mammals, most notably in the u...

Although methods about building fish-like robots have attracted much research in recent years, new techniques are still required for developing superior robot fish. This paper presents a novel robot fish propelled by an active compliant propulsion mechanism. The key innovation is the combination of an active wire-driven mechanism with a soft compliant tail to accomplish subcarangiform swimming ...

Adjustable compliant actuators are being designed and implemented in robotic devices because of their ability to minimize large forces due to impacts, to safely interact with the user, and to store and release energy in passive elastic elements. Conceived as a new force-controlled compliant actuator, an adjustable rigidity with embedded sensor and locking mechanism actuator (ARES-XL) is present...

We present a real-time haptics-aided injection technique for biological cells using miniature compliant mechanisms. Our system consists of a haptic robot operated by a human hand, an XYZ stage for micro-positioning, a camera for image capture, and a polydimethylsiloxane (PDMS) miniature compliant device that serves the dual purpose of an injecting tool and a force-sensor. In contrast to existin...

Compliant bistable mechanisms with planar configurations demonstrate two in-plane stable states through the nonlinear deformations of flexible segments, which are widely used in field shock sensors and threshold sensors. In these mechanisms, consistent dynamic static behaviors difficult to maintain under influence an out-of-plane load. This is limited some applications where precise displacemen...
