Planar Quasi-static Motion Of A Lamina With Uncertain Contact Friction
نویسنده
چکیده
Planning t>he motion of bodies in cont,act requires a model of contact rnechanics in order to predict sliding, rolling, and jamming. Such a model t'ypi-cally includes estimates of the coefficients of friction. Though, usually assumed t,o be constant, these coefficients vary and are difficult to measure. In this paper, we treat, the coefficient,s of friction as independent variables and derive regions in t,he space of friction coefficients that correspond to par-ticiilar modes of motion; three sliding corit,acts or one sliding and one rolling coiit,act, all otlier coil-tacts separating.

A Fast Stochastic Contact Model for Planar Pushing and Grasping: Theory and Experimental Validation
Based on the convex force-motion polynomial model for quasi-static sliding, we derive the kinematic contact model to determine the contact modes and instantaneous object motion on a supporting surface given a position controlled manipulator. The inherently stochastic object-to-surface friction distribution is modelled by sampling physically consistent parameters from appropriate distributions, ...
متن کاملQuasi-static contact problem with finitely many degrees of freedom and dry friction
A quasi-static contact problem is considered for a non-linear elastic system with finitely many degrees of freedom. Coulomb’s law is used to model friction and the friction coefficient may be anisotropic and may vary along the surface of the rigid obstacle. Existence is established following a time-incremental minimization problem. Friction is artificially decreased to resolve the discontinuity...
متن کاملSpatial Compliant Motion of a Rigid Body Constrained by a Frictional Contact
In this paper, we study the quasi-static motion of an elastically suspended, unilaterally constrained rigid body. The motion of the rigid body is determined, in part, by the position controlled motion of its support base and by the behavior of the elastic suspension that couples the part to the support. The motion is also determined, in part, by contact with a frictional surface that both coupl...
متن کاملCooperative Towing with Multiple Robots
In this paper, we address the cooperative towing of payloads by multiple mobile robots in the plane. Robots are attached to a planar object or a pallet carrying a payload by cables. Coordinated motion by the robots allow the payload to be manipulated through a planar, warehouse-like environment. We formulate a quasi-static model for manipulation and derive equations of motion that yield the mot...
متن کاملNew results on the stability of quasi-static paths of a single particle system with Coulomb friction and persistent contact
In this paper we announce some new mathematical results on the stability of quasistatic paths of a single particle linearly elastic system with Coulomb friction and persistent normal contact with a flat obstacle.A quasi-static path is said to be stable at some value of the load parameter if, for some finite interval of the load parameter thereafter, the dynamic solutions behave continuously wit...
