Distributed manipulation with stick-slip contact

Proceedings 2003 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2003) (Cat. No.03CH37453), 2004
Actuator arrays are planar arrangements of two degree-of-freedom actuators that cooperatively translate and orient objects for efficient manipulation. This paper derives the equations of motion for an object with the friction interface switching between slip and no-slip contact at each actuator. A controller derived from kinematics is presented and its

Slip detection with distributed-type tactile sensor

2004 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2005
This paper describes development of a distributed-type tactile sensor. This sensor arranges many sensor elements that can measure a triaxial force on the same plane. Therefore, the action force can be measured with the pressure distribution. Since the relative movement of a sensor and a contacted object can be evaluated by measuring the pressure ...

A-optimal design method to determine the regularization parameter of coseismic slip distribution inversion

, 2020
The key to the inversion of a coseismic slip distribution is to determine the regularization parameters. In view of the determination of regularization parameters in seismic slip distribution inversion, the A-optimal design method is proposed in this ...

Effects of fault slip distribution on the geometry and kinematics of the southern Junggar fold-and-thrust belt, northern Tian Shan

Tectonophysics, 2019
At the foreland edge of fold-and-thrust belts (FTBs), tectonic shortening could either be accommodated by thick-skinned faulting and/or structural wedges developed near range-fronts, or be transferred along detachment layers further into basins, forming ...

Incipient Slip Detection Method With Vision-Based Tactile Sensor Based on Distribution Force and Deformation

IEEE Sensors Journal, 2021
Slip detection, especially incipient slip, plays a very important role in achieving stable robot grasp, whereas the fine and reliable measurement of incipient slip has not been well addressed.

Source parameters and slip distribution of the 2018 M 7.5 Palu, Indonesia earthquake estimated from space-based geodesy

, 2019
The 2018 Mw 7.5 Palu earthquake is one of the most geometrically complex events ever recorded on Central Sulawesi Island. It caused devastating tsunamis and landslides after the mainshock, resulting in great casualties and damages to the infrastructures ...

Surface rupture and slip distribution along the Lenglongling fault in the NE Tibetan Plateau: Implications for faulting behavior

Journal of Asian Earth Sciences, 2019
The Lenglongling Fault (LLLF) is located in the western section of the “Tianzhu seismic gap” along the Qilian-Haiyuan fault zone in the NE Tibetan Plateau, between the 1920 M8.5 Haiyuan and the 1927 M8.0 Gulang earthquakes.

Hypocentral dependent shallow slip distribution and rupture extents along a strike-slip fault

Earth and Planetary Science Letters, 2022
Abstract Natural faults feature heterogeneities in geometry, material properties, and stress distributions, posing great challenges in predicting fault slip behaviors. Among these factors, the stress on the fault is poorly understood due to the lack of direct measurements.

INTRINSIC MODE FUNCTIONS OF EARTHQUAKE SLIP DISTRIBUTION

Advances in Adaptive Data Analysis, 2010
In this paper, empirical mode decomposition technique is used to analyze the spatial slip distribution of five past earthquakes. It is shown that the finite fault slip models exhibit five empirical modes of oscillation. The last intrinsic mode is positive and characterizes the non-stationary mean of the slip distribution.

Displacement Hazard from Distributed Ruptures in Strike-Slip Earthquakes

Bulletin of the Seismological Society of America, 2023
ABSTRACTWidespread distributed fracturing during earthquakes threatens infrastructure and lifelines. We combine high-resolution rupture maps from the five major surface-rupturing strike-slip earthquakes in southern California and northern Mexico since 1992 to incorporate the displacements produced by distributed ruptures into a probabilistic ...
