Stick–slip in hand guidance of palletizing robot as collaborative robot
International Journal of Advanced Robotic Systems, 2022 Stick–slip is a challenging problem in palletizing robots and constitutes one of the main problems in precision positioning control. This study analyzed the stick–slip of a four-degree-of-freedom ceiling-mounted hand-guiding collaborative robot in a ...

Imaging the stick-slip peeling of an adhesive tape under a constant load [PDF]
, 2007 Using a high speed camera, we study the peeling dynamics of an adhesive tape under a constant load with a special focus on the so-called stick-slip regime of the peeling. It is the first time that the very fast motion of the peeling point is imaged.

Stick-Slip Motion and Phase Transition in a Block-Spring System
, 2002 We study numerically stick slip motions in a model of blocks and springs being pulled slowly. The sliding friction is assumed to change dynamically with a state variable.

Electronic friction and liquid-flow-induced voltage in nanotubes [PDF]
, 2004 A recent exciting experiment by Ghosh et al. reported that the flow of an ion-containing liquid such as water through bundles of single-walled carbon nanotubes induces a voltage in the nanotubes that grows logarithmically with the flow velocity v0.
