This paper presents an automatic optimization method for compliant constant force mechanisms, which eliminates the need time-consuming parameter tuning and complex model design in conventional process. The proposed framework is based on finite-element analysis (FEA) multi-objective genetic algorithm (MOGA) methods designed two steps: First, preliminary mechanism carried out to roughly encompass...

In this letter, we propose a novel constant-force end-effector (CFEE) to address current limitations in robotic ultrasonography. The CFEE uses parallel, motor-spring-based solution precisely generate constant operating forces over wide range and enable the ultrasound (US) probe adapt abdominal contours autonomously. A displacement measurement unit was developed realize acquisition of position p...

We revisit the rapid stretching of a liquid filament under the action of a constant imposed tensile force, a problem which was first considered by Matta & Tytus [JNNFM vol. 35, pp 215-229, 1990]. A liquid bridge formed from a viscous Newtonian fluid or from a dilute polymer solution is first established between two cylindrical disks. The upper disk is held fixed and may be connected to a force ...

We solve the stochastic equations for a cluster of parallel bonds with shared constant loading, rebinding, and the completely dissociated state as an absorbing boundary. In the small force regime, cluster lifetime grows only logarithmically with bond number for weak rebinding, but exponentially for strong rebinding. Therefore rebinding is essential to ensure physiological lifetimes. The number ...
