During the last five years, we developed two types of humanoid arms called as RoMAN and RAMeX. RAMeX has been developed for imitating human arm motions with low cost, whereas RoMAN is a high-end humanoid arm module with micrometer precision. The authors have noticed that such humanoid arms and the robotic arms for surgery have a close similarity in their functions and structures. All of them imitate...
This paper reports an in-depth study of a hybrid microassembly technique that combines a robotic micromanipulator and a water droplet self-alignment, which greatly improves the performance of robotic microassembly. The method is experimentally studied on a custom-made microrobotic test platform adapted for the experiments. Four important measures of the microassembly technique are investigated--yield,...
Evolutionary improvements in tooling and techniques are allowing increasingly complicated waveguide circuits to be fabricated with conventional end-mill machining at frequencies ranging from millimeter-wavelengths up to several terahertz. Machining precision is now approaching the limits of what can be measured with an optical microscope, with the measured dimensions of the highest-precision components...
