13. Experimental validation of a 3-D vision-based measurement system applied to robot calibration
One of the problems that slows the development of off-line programming is the low static and dynamic positioning accuracy of robots. Robot calibration improves the positioning accuracy and can also be used as a diagnostic tool in robot production and maintenance. A large number of robot measurement systems are now available commercially. Yet, there is a dear

14. ESTUDO DE SISTEMAS ATIVOS PENDULARES PARA O TRANSPORTE EM VEÍCULOS COM CARGAS SENSÍVEIS A DISTÚRBIOS / STUDY OF PENDULAR ACTIVE SYSTEMS FOR THE TRANSPORT IN VEHICLES OF LOADS SENSIBLE OF DISTURBANCES
Cranes are very used mechanical devices to load and to unload objects and/or to carry them in industries and warehouses. The movement of the crane is controlled by an operator or is programmed and controlled automatically. In the two cases, the movement of the crane cause undesirable swings of the load and claw, leading to an idle time before the grasping an

15. Assembly and positioning of microtubule asters in microfabricated chambers
Intracellular organization depends on a variety of molecular assembly processes; while some of these have been studied in simplified cell-free systems, others depend on the confined geometry of cells and cannot be reconstructed using bulk techniques. To study the latter processes in vitro, we fabricated microscopic chambers that simulate the closed environme
