The microprogrammed Data General Eclipse S/200 computer is available with a writable control store (WCS). The WCS feature of the Eclipse is an extension of the microprogrammed control logic of the computer's central processing unit. It allows a user to implement specialized instructions at a very low level.

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 ...

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.

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.

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.

Integration of Microcircuitry Into Microassemblies
IRE Transactions on Military Electronics, 1961The necessity to hybridize newer microcircuitry techniques with existing design capabilities to achieve efficient equipment designs is established. An analysis is presented of the net size and weight advantages calculated for several components of a typical weapons system, as first the micromodule and then, progressively, thin-film and solid-circuit ...

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.

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

Microassembly of spheroids by thermoresponsive gel probe
2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2014In this paper, manipulation of cell spheroids was conducted to construct 3D cell structures for tissue engineering applications. The spheroids were manipulated using thermoresposnive gel, and the cell viability was checked. The manipulated cells show more than 90 % viability.
