The sub-project "robot-based handling" targets at solving known bottlenecks when handling and assembling micro parts using current robotic technologies. In the state-of-the-art description, it has been clearly shown that the following issues need to be addressed for future microassembly systems: 

  • Development of miniaturized robots that can achieve sub-micrometer precision (100 nm targeted) at high-speed. A prerequisite to achieve this goal is to develop very small actuators and sensors as basic components for these robots.

  • Handling and fixing microparts reliably and precisely is the main bottelneck in microassembly and is far from being solved today. Further handling and fixing strategies must be developed to address the demonstrators of this project. Also the environmental influences are usually not mastered and will be studied. 

  • Tools for assisting the robot in complex microassembly tasks are not available today. Components such as 3D microvision systems, micropart feeders, miniature grippers with force sensing capability and ways to control the robot based on this information will be developed.

  • Available robot systems are difficult to program today. This is especially true for microassembly systems, because the parts to manipulate are not visible for human operators. There is a need to develop intelligent programming interfaces to introduce successfully the robot systems into industry.
