What is Micro-Assembly?

As per [ 6 ], micro-assembly is the “discipline of positioning, orienting, and assembling of micron-scale components into complex microsystems”. The goal of micro-assembly is to provide a means to achieve hybrid micro-scale devices of high complexity while maintaining high yield and low cost [ 6 ].

What is the approach to micro-assembly?

Furthermore, the approach to micro-assembly includes the development of micro-robots that could be fabricated on the same wafer with the parts, avoiding the need for an external assembly system. Due to the difficulties in fabrication and sensors and actuators integrations, the micro-robot design has to be simple [ 13 ].

What is an example of micro-assembly planning?

An example of micro-assembly planning with the use of a Van der Waals gripper is presented in [ 64 ]. A strategy downsized from the macro-world is the use of the force generated by the pressure difference between the gripper and the atmosphere. Indeed, vacuum grippers are commonly used in the assembly of fragile macro-components [ 65 ].

What are the different types of micro-assembly approaches?

Based on the level of automation, micro-assembly approaches can be divided into: automated assembly, based on the use of high-performance robots, precision stages and micro-gripping tools which constitute an assembly work-cell . The system could exploit vision feedback, force feedback, or their combination.

What is robotic micro-assembly?

Robotic micro-assembly can be often seen as a serial automated approach, carried out in a micro-assembly work-cell or a specific space of a micro-factory , whose main devices are miniaturised robots (fixed or mobile), other micro-positioning devices (e.g. micro-stages), micro-grippers , micro-feeders, sensing and control equipment.

What is vision-based control in micro-assembly systems?

Since a vision system is absolutely indispensable in micro-assembly systems, the use of vision-based control is the obvious choice. The key to visual control is the use of image information in the motion control loop of the devices (e.g. robot), called visual servoing.
