“…Numerous solutions are possible: designing environmental isolation platforms [17] [18], considering noise limitation during the design of micromanipulation systems by an appropriate choice of the resonance frequency of end effectors [19], or using appropriate controllers for noise rejection [20]. Multi-noise isolation platforms are generally very expansive and have a limited volume which can be a real problem if a micromanipulation station requires a large working space [21].…”

Abstract:Efficient and dexterous manipulation of very small (micrometer and millimeter sized) objects require the use of high precision micromanipulation systems. The accuracy of the positioning is nevertheless limited by the noise due to vibrations of the end effectors making it difficult to achieve precise micrometer and nanometer displacements to grip small objects. The purpose of this paper is to analyze the sources of noise and to take it into account in dynamic models of micromanipulation systems. Environmental noise is studied considering the following sources of noise: ground motion and acoustic noises. Each source of noise is characterized in different environmental conditions and a separate description of their effects is investigated on micromanipulation systems using millimeter sized cantilevers as end effectors. Then, using the finite difference method (FDM), a dynamic model taking into account studied noises is used. Ground motion is described as a disturbance transmitted by the clamping to the tip of the cantilever and acoustic noises as external uniform and orthogonal waves. For model validation, an experimental setup including cantilevers of different lengths is designed and a high resolution laser interferometer is used for vibration measurements. Results show that the model allows a physical interpretation about the sources of noise and vibrations in millimeter sized micromanipulation systems leading to new perspectives for high positioning accuracy in robotics micromanipulation through active noise control.

This paper provides a review of techniques and technology relevant to the field of micro-devices assembly (MDA). MDA is an emerging domain of importance which is expected to have a substantial impact on a range of industrial fields including sensors, surveillance devices, and semiconductor devices. This paper provides a review of a cross-section of research including micro-gripping design and manipulation techniques, work cell design and factory automation, selfassembly techniques, and virtual reality-based approaches in micro-assembly. A discussion of the key challenges for this domain along with directions for future research is also provided.

Abstract.A tele-haptic system for microassembly applications is currently being developed at the Delft University of Technology, with the goal of achieving superior performance by providing enhanced feedback to the human operator. Assembly of a micro-harmonic drive is used as a benchmark to fully evaluate the proposed tele-haptic system by investigating the control strategies and the individual subsystems: master device, microgrippers and slave system. The master device will be comprised of a parallel robot with a built-in gripper. The slave system and end effector are focused on providing efficient and effective force feedback of the interactions on the microenvironment to the human operator, in addition to detecting position and orientation of the object being grasped. Novel control strategies are also investigated to allow the transmission of high frequency transients to the operator, carrying information from hard contact interactions between the microgripper and the part to be assembled.
