Contact Force Decomposition Using Contact Pressure Distribution

IEEE Robotics and Automation Letters, 2017
Many robotics applications involving contact with objects require the decomposition of an external force measured by a force sensor into its normal and shear components. In this paper, we present a general and effective contact force decomposition method based on the contact pressure distribution.

Calculation of contact forces

Proceedings of the ACM symposium on Virtual reality software and technology, 1999
Detecting collisions and calculating physically correct collision responses play an important role when simulating the dynamics of colliding rigid bodies. VR-applications such as virtual assembly planning and ergonomy studies can especially profit from advances in these directions, because they enable an interactive and intuitive manipulation of ...

Electromagnetic forces on contacts

2008 43rd International Universities Power Engineering Conference, 2008
These instructions give you basic electromagnetic force on an arcing contact is one of the principal factors in designing large-capacity and small-sized high current contact systems of circuit breakers, disconnectors or isolated switches. Butt contacts, such as those in vacuum interrupters, tulip contacts structured from a rod contact and fingers are ...

Forces between membranes approaching contact

Scandinavian Journal of Clinical and Laboratory Investigation, 1981
Cell stickiness to surfaces is recognized as an important concern in tests of red cell filterability. Many forces need to be considered in order to think about the sources of cell sticking. As cell membranes are brought together they experience successively the domination of several classes of forces van der Waals attraction, electrostatic repulsion ...

Non-contact lateral force microscopy

Journal of Physics: Condensed Matter, 2017
The goal of atomic force microscopy (AFM) is to measure the short-range forces that act between the tip and the surface. The signal recorded, however, includes long-range forces that are often an unwanted background. Lateral force microscopy (LFM) is a branch of AFM in which a component of force perpendicular to the surface normal is measured.

Atomic force profiling by utilizing contact forces

Journal of Applied Physics, 1988
Atomic force microscopy (AFM) is a new technology currently being developed. Stylus profilometry (SP) was developed earlier. A procedure is reported here which combines features of both SP and AFM. In this approach a stylus scans a sample surface and responds to contact forces.

Contact Tasks Realization by Sensing Contact Forces

1997
A key issue in robotized realization of any type of the contact task is the control of forces arising during contact between the object and the environment. The most common way of force measurement is with a force sensor, usually placed at the robot wrist, which can measure all six components of force and moment.

Electrostatic and contact forces in force microscopy

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1991
We have been measuring the electrostatic and contact forces between a tip and a graphite surface in a force microscope, which uses a polarizing optical interferometer. For large distances where the electrostatic force predominates, the data are analyzed in terms of a model which introduces the elongated shape of an actual tip.

Hip joint contact forces during stumbling

Langenbeck's Archives of Surgery, 2004
To determine whether load directions for stumbling are similar to those for common activities and whether stumbling can be realistically simulated under laboratory conditions without endangering the patients.The magnitudes and directions of hip contact forces were measured during real and simulated stumbling and compared with those found during various
