Robotic microassembly for meso-scale application
Industrial Robot: An International Journal, 2015Purpose – The purpose of this paper is to design and develop 14-degree of freedom (DOF) robotic micromanipulator with which LIGA devices and axle hole part can be both manipulated and assembled. Design/methodology/approach – The in-house robotic microassembly ...

Autofocus for automated microassembly under a microscope
Proceedings of 3rd IEEE International Conference on Image Processing, 2002A motorized microscope is used as optical sensor for automated microassembly. To achieve the required resolution range an automated autofocus system is indispensable. Since we are equipped to acquire and process microscopic images we follow a passive approach to autofocusing based on image processing.

Visual servoing and CAD-driven microassembly
IEEE Robotics & Automation Magazine, 1998The authors describe current research and development on a robotic visual servoing system for assembly of LIGA (lithography galvonoforming abforming) parts. The workcell consists of an AMTI robot, precision stage, long working distance microscope, and LIGA fabricated tweezers for picking up the parts.

Automated microassembly of tissue engineering scaffold
2010 IEEE International Conference on Robotics and Automation, 2010This video presents a fully automated desktop workstation for fabricating tissue engineering (TE) scaffolds by assembling microscopic building blocks of dimension 0.5 × 0.5 × 0.2mm3 and 60µm thickness. A TE scaffold is a porous supporting structure made of biodegradable material for cells to attach to and proliferate.

An Ungrounded Master Device for Tele-Microassembly
2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018Micro-assembly is a challenging issue for automation due to particularities of micro-world physics and limitations on sensors. Consequently, most applications are human-operated often with basic joystick-like interfaces. Beside being nonintuitive, these solutions do not provide their users with a meaningful insight into the microworld.

Rapidly Prototyped Orthotweezers for Automated Microassembly
Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007We describe the design, fabrication, and testing of an ultra-low cost orthotweezers system for microassembly. By utilizing rapid prototyping technology, compliant mechanisms, and commodity-grade actuators and sensors, we significantly reduce the complexity and cost of the previous Orthotweezers system without sacrificing functionality.

Caging grasps for micromanipulation & microassembly
2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011In this paper, we demonstrate a systematic way to determine configurations for up to four coordinated micro-manipulators to form caging grasps for transporting micro-scale planar, polygonal parts. We exploit the geometry of the part, noting the presence and location of convex corners and non-convex corners, and form opposing force equivalents with the ...

Microassembly planning for manufacturing by flexible microrobots
Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002Automation of highly precise microassembly steps will make it easier to realize low cost microsystems. For this, a microrobot-based microassembly desktop station is being developed at the University of Karlsruhe. In this paper, we suggest a common microassembly model for a computer-aided microassembly planning-which is based on geometric reasoning-and ...

Towards fully-automated micrograsping for microassembly
2008 10th International Conference on Control, Automation, Robotics and Vision, 2008Fully automated microassembly procedure has become an essential subject of interest among microsystem researchers due to the promising potential of the establishment of fully functional Micro Electro Mechanical System (MEMS) devices and significant cost reduction on large number of consumer based products once the system is realized.

Parallel microassembly with electrostatic force fields
Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002Microscopic (submillimeter) parts are often fabricated in parallel at high density but must then be assembled into patterns with lower spatial density. We propose a new approach to microassembly using: 1) ultrasonic vibration to eliminate friction and adhesion; and 2) electrostatic forces to position and align parts in parallel. We describe experiments
