Under an NSF REU center grant REU-0755355 entitled “Micro/Nano Assembly Workcell Via Micro Visual Sensing and Haptic Feedback”, Texas A&M University – Corpus Christi and Texas State University – San Marcos collaboratively hosted two groups of 10 students from different backgrounds for 10 weeks each in Summer 2008 and 2009 respectively.  The research effort involved is part of an ongoing research program developing novel methods for making automated micromanipulation systems.  The twenty students and two teachers were divided into four teams developing interrelated aspects of the project.  The first team developed the micro-scale parts, such as gears, for assembly.  This required the team to develop techniques for etch and release of three dimensional parts from a silicon substrate.  The second team developed the microscopic vision system used for locating and identifying parts on a silicon wafer.  The vision system is used to determine the position on the wafer of the parts, their diameter (one of several standard parts), and, utilizing a novel technique developed by the team, the thickness of the parts.  The third team developed a robotic platform able to locate any portion of a wafer for manipulation within a three-dimensional space with 10μm accuracy.  This mechanism is used to first bring any desired portion of the wafer to the vision system for analysis and also to bring a manipulator to “pick and place” parts using the vision system for feedback.  The fourth group developed the micro-manipulator in the form of a “gripper” powered by electro-active polymer.  This gripper was capable of accurately and repeatably gripping, lifting, moving, placing, and releasing parts at any point within the workspace.  Collectively, the REU project successfully produced a prototype system advancing the state-of-art for an important are of micro-manufacturing while offering a stimulating experience for undergraduate students.  Assessment of the student experience showed an increase in the likelihood for these students to pursue engineering careers and to encourage their peers to consider STEM careers.

“…For example, a comprehensive study showed the assembly cost is more than half of the microdevice cost. 5 Although many institutes have been involved in the micro/nano manufacturing studies in recent decades, a full blown solution with flexible manufacturing either by manual or autonomous assembly operations. Due to the tedious and time consuming assembly works by manual operator, innovative autonomous assembly platforms are in essential demand.…”

In this paper, we developed a flexible micro workcell for micro part assembly and bio materials handling. The primary focus of the research is on the flexible manufacturing system that can handle parts in the size of 100 to 500 µm for various applications. Flexibility in micro assembly, though important, has not been examined in depth due to the complexity of micro operations of small parts. Micro gears, micro glass fibers or fragile bio materials require flexibility in gripping and haptic feedback control for further operation.To that end, we design grippers made out of electro active polymer, controlled by high precision micro manipulator for a novel micro assembly process, namely flexible micro assembly system (FMAS). The areas of research include micro/nano electro-mechanical system (MEMS) material and structure, micro sensor/actuator system, visual feedback control system, micro-robotic arm motion control and flexible micro-gripper system. In order to verify the functional aspect of the FMAS, we made micro mechanical gears fabricated via bulk micromachining technology for 3D micro vision capability and handling precision of micro robotic manipulator.

This paper focuses on temporary fixing systems for microrobotics. Several solutions from the state of the art are presented and compared: solutions based on mechanical bending, electromagnetic elements, electrostatic forces, glues, polymers or Van der Waals forces. From this analysis, we designed and developed a new system based on thermal glue (that permits to exchange the tip part of a microgripper) for microassembly stations. This system brings a high flexibility and compactness for microrobotic applications.
