Micro robotics is a significant area to be able to manipulate micro level objects dexterously. Until now, various micro manipulation systems have been presented. In micro environment, different kinds of objects have different dimensions. Some of them are a few micrometers (??m) such as donor cells, some of them are more than a hundred ??m such as egg cells. At this point, a manipulator which has multi-scale...
We have proposed the attentive workbench (AWB), which helps workers to perform tasks at their desks from both informational and physical sides. In this report, we propose a method for constructing pointing gesture-based input interface in AWB in the view of usability. The usability is evaluated by the necessary time for users to accomplish deskwork tasks.
A micro hand consisting of two rotational fingers is proposed. Each finger has 4 DOF: 3-DOF translation and 1-DOF rotation around the finger's axis. Two fingers grasp a small object and translate it in 3D space by moving themselves in the same direction. They can rotate the object by moving themselves back and forth in the opposite direction. Rotating the fingers around their own axes in the same...
The optimization and design process of a two-fingered micro hand that uses a hybrid motion mechanism is presented. The hybrid hand consists of two 3-PRS parallel modules - upper and lower - connected serially back to back in a mirror image style. It is driven by piezo-electric actuators and has two long glass petites as end effectors. The most important part in the development process is the optimization...
