This paper presents a general dynamic model that describes the two-dimensional grasp by two robotic fingers with soft fingertips. We derive the system's kinematics and dynamics by incorporating rolling constraints that depend on the deformation and on the rolling distance characteristics of the fingertips' material. We analyze the grasp stability at equilibrium, and conclude that the rolling properties of the fingertips can play an important role in grasp stability, especially when the width of the grasped object is small compared to the radius of the tips. Subsequently, a controller, which is based on the fingertips' rolling properties, is proposed for stable grasping concurrent with object orientation control. We evaluate the dynamic model under the proposed control law by simulations and experiments that make use of two different types of soft fingertip materials, through which it is confirmed that the dynamic model can successfully capture the effect of the fingertips' deformation and their rolling distance characteristics. Finally, we use the dynamic model to demonstrate by simulations the significance of the fingertips' rolling properties in grasping thin objects.

In the cognitive development, students of elementary school need a real object in the learning process which has an impact on elementary school teachers who have to be able to make their own properties. The purpose of this community service is to provide information to teachers of SD Ana Maritim Surabaya to make the simple and easy media. Stages took in the process are: the participants formed a group of three and each group consists of three or four participants. Each group got the tools and materials needed to make props. Participants created props according to the directions available on given hand-out. The result of this community services are (1) the participants are making mathematical props using paper--coins integer and various forms of two-dimensional figure and (2) for Science media, participants created jumping can and coloured water in bottles.

QR Code is a type of two-dimensional bar code in the form developed by Denso Wave, a division of Denso Co. Corporation, a perudahaan in Japan, which was published in 1994. Barcode is a symbol marking the real object made of sticks pattern of black and white in order manage computer is easy to recognize a good student attendance data is needed to be able to provide ease in generating student attendance data and is one of the important factors in managing a good attendance data. Management of student attendance by using a QR Code-based Web is an application that will be built in "SMP Negeri 11 of Sukabumi" because attendance is still used is conventional systems, such as pengabsensian with books attendance and report absences still slow, so it can hinder time , to overcome the above problems, the authors propose a way of solving that is the making of a computer application which is expected with this system can reduce and minimize errors and problems that occur.

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.
