In this paper we present a discrete model governing the deformation of convex regular polygon subjected not to cross given flat rigid surface, on which it initially lies in correspondence one point only. First, set up form variational inequalities posed over non-empty, closed and subset suitable Euclidean space. Secondly, show existence uniqueness solution. The provides simplified illustration ...

This paper discusses a method for identification of contact conditions from the information of 6-axes force sensor equipped with a robot hand. The previous paper has the following problems. (1) The noise of sensing force was not considered. (2) Hence, the estimates obtained by the previous method are biased from true value, and the identification of contact types depends on an unknown contact p...

in this paper, the dynamics of evaporation of water droplets on surfaces with different contact angle hysteresis is studied experimentally and theoretically. the evaporation of water droplets on surfaces usually occurs in three distinct stages, namely the constant contact area mode, followed by the constant contact angle mode, and the mixed mode in which both contact angle and contact area are ...

there have been many researches on object grasping in cooperating systems assuming no object slippage and stable grasp and the control system is designed to keep the contact force inside the friction cone to prevent the slippage. however undesired slippage can occur due to environmental conditions and many other reasons. in this research, dynamic analysis and control synthesis of a cooperating ...
