Micro assembly is typically characterised by positioning tolerances below a few micrometers. In the case of a hybrid micro system assembly, such as optical glass fibres, micro ball lenses or micro probes for measurement tasks, even positioning accuracies in the sub-micrometer range have to be achieved. Due to the need for highly accurate assembly systems and extensive alignment procedures the a...

The micro-conveyor is a 9 × 9 mm manipulation surface able to move millimeter-sized planar objects in the four cardinal directions using air flows. Thanks to a specific design, the air flow comes through a network of micro-channels connected to an array of micro-nozzles. Thus, the micro-conveyor generates an array of tilted air jets that lifts and moves the object in the required direction. In ...

This paper presents the autonomous micro aerial vehicle pilot, a new autopilot platform weighing 6.25 g and measuring 11.3 cm2, specifically designed for use on micro/miniature aerial vehicle mobile sensing platforms. An overview of the hardware, firmware, ground station, and validation testing used to demonstrate this autopilot as a viable research instrument for atmospheric thermodynamic sens...

In this paper, we propose a framework to systematically analyze the structural form and thematic content of codes of ethics related to Information and Communication Technology (ICT codes of ethics). Then we apply this framework, within a sample of 30 organizations. Our purpose is to assess the organizational ethical positioning advocated by these ICT codes of ethics, using an adaptation of Kohl...

Accurate control and precise positioning of opto-thermocapillary flow-addressed bubble microrobots are necessary for micromanipulation. In addition, micromanipulation using the simultaneous actuation of multiple microrobots requires a robust control system to enable independent motion. This paper demonstrates a hybrid closed-loop vision-assisted control system capable of actuating multiple micr...

The finite element procedure is developed for the solution of three-dimensional geometrically nonlinear problems with small strains and large rotational and translational displacements. Updated Lagrangian formulation is used with controlling strains and stresses at local coordinate frames at element integration points. Equilibrium iterations at each step are performed according to the Newton-Ra...

Since micro/nano positioning devices are increasingly being made of parallel manipulators due to their characteristics, the precision analysis of a class of parallel platform for micro/nano positioning applications is proposed in this paper. The kinematics model of the dual parallel mechanism system is established via the stiffness model of individual wide-range flexure hinge and then the resul...

INTRODUCTION The North American manufacturing industry has seen a growing demand for precision machined components in recent years. Biomedical devices, micro-optical moulds, and automotive parts are examples of precision manufactured components. Traditional milling practices have reached the limit of the machines’ accuracy and cannot achieve high tolerances now demanded in the micro-machining f...

Coordinated manipulation of micro-scale objects is critical for advancing several emerging applications such as microassembly and manipulation of biological cells. Most of the existing designs for micromanipulators are designed to accomplish primarily spatial positioning functionalities using positioning stages. Relatively, there are very few micromanipulators capable of ‘grip-and-place’ functi...
