This paper describes the contact formation modeling for the identification of geometrical parameters (positions, orientations and dimensions) of rigid polyhedral objects in contact during the force-controlled execution of contact formation sequences. Following improvements with respect to the state of the art are made: (i) the modeling effort is reduced considerably, (ii) the generation of the ...

The concepts of the experimental design system that are discussed are feature modeling and geometrical constraints. The main technique for creating the user environment is Virtual Reality. Feature modeling forms the basis for managing the design data. To start with, data storage is implemented in a Relational Data Base Management System. Along with this a (traditional) interface is developed fo...

Dissections of simple geometrical forms can be used to train students’ spatial understanding and to teach geometrical modeling as well as some of the practical aspects of rapid prototyping by layered manufacturing. Two types of dissection puzzles have been used as class exercises in a graduate course on computer-aided solid modeling: Helicoidal sectioning of simple geometrical shapes and a burr...

Mini and micro robots, which can swim in an underwater environment, have drawn widespread research interests because of their potential applications to the clinical drug delivery, biotechnology, manufacturing, mobile sensor networks, etc. In this paper, a prototype of microrobot based on the motion principle of living microorganisms such as E. Coli Bacteria is presented. The properties of this ...
