Contact forces in roughness discrimination [PDF]
Scientific Reports, 2020 AbstractRoughness perception through fingertip contact with a textured surface can involve spatial and temporal cues from skin indentation and vibration respectively. Both types of cue may be affected by contact forces when feeling a surface and we ask whether, on a given trial, discrimination performance relates to contact forces. We examine roughness

Contact forces in a granular packing [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1999 We present the results of a systematic numerical investigation of force distributions in granular packings. We find that all the main features of force transmission previously established for two-dimensional systems of hard particles hold in three-dimensional systems and for soft particles, too.

Sensorimotor control of contact force [PDF]
Current Opinion in Neurobiology, 2008 Interacting with objects in the environment introduces several new challenges for motor control: the potential for instability, external constraints on possible motions and novel dynamics. Grasping and manipulating objects provide the most elaborate examples of such motor tasks.

Contact force observer for space robots [PDF]
2019 IEEE 58th Conference on Decision and Control (CDC), 2019 In this paper, the problem of estimating a contact wrench at the end-effector for a space robot is addressed. To this aim, a generalized force observer based on a base-joints dynamics is first reviewed. Then, a different formulation is proposed, which is based on a centroidal-joints dynamics.

Machines, 2023 A ball cage flexible drill pipe is a new type of ultra-short-radius drilling tool, which consists of multiple flexible joints hinged together. During the drilling process, the flexible members will come into contact and wear, which reduces the efficiency

Forcing contact inhibition of locomotion
Trends in Cell Biology, 2015 Contact inhibition of locomotion drives a variety of biological phenomenon, from cell dispersion to collective cell migration and cancer invasion. New imaging techniques have allowed contact inhibition of locomotion to be visualised in vivo for the first time, helping to elucidate some of the molecules and forces involved in this phenomenon.

Estimation of contact forces using a virtual force sensor [PDF]
2014 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2014 Physical human-robot collaboration is character- ized by a suitable exchange of contact forces between human and robot, which can occur in general at any point along the robot structure. If the contact location and the exchanged forces were known in real time, a safe and controlled collaboration could be established.

Closed-Form Equations for Contact Force and Moment in Elastic Contact of Rough Surfaces
Modelling and Simulation in Engineering, 2011 It is reasonable to expect that, when two nominally flat rough surfaces are brought into contact by an applied resultant force, they must support, in addition to the compressive load, an induced moment.

Force‐Sensing Catheters During Pediatric Radiofrequency Ablation: The FEDERATION Study
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017 Background Based on data from studies of atrial fibrillation ablations, optimal parameters for the TactiCath (TC; St. Jude Medical, Inc) force‐sensing ablation catheter are a contact force of 20 g and a force‐time integral of 400 g·s for the creation of ...
