This paper proposes an automatic facial expression recognition system, which uses new methods in both face detection and feature extraction. In this system, considering that facial expressions are related to a small set of muscles and limited ranges of motions, the facial expressions are recognized by these changes in video sequences. First, the differences between neutral and emotional states are detected. Faces can be automatically located from changing facial organs. Then, LBP features are applied and AdaBoost is used to find the most important features for each expression on essential facial parts. At last, SVM with polynomial kernel is used to classify expressions. The method is evaluated on JAFFE and MMI databases. The performances are better than other automatic or manual annotated systems.

This paper presents recent research progress in the manufacturing of MEMS based robotic positioning technology. The goal is to configure a nanofactory consisting of multiple microrobots that combine high precision with high throughput along with other application-specific requirements such as strength, dexterity, and work volume. This requires design to satisfy part mobility and dexterous manipulation with high precision. The first microrobot called the Articulated Four Axes Microrobot (AFAM) is a 3D dexterous micromanipulator robot, and we describe nano indentation experiments using AFM tips mounted on the microrobot. By combining positioning data obtained using laser interferometers and SEM imaging of nano indentation data, precision metrics such as accuracy, repeatability and resolution of the AFAM robot are determined. Preliminary reliability findings are presented. The second robot type is the ARRIpede microcrawler, and we present recent progress in microrobot precision evaluation including motion resolution and repeatability. Using these two microrobots as basic positioning and manipulation units, a nanoassembly module concept for hybrid nano assembly applications is proposed. In this paper we present recent progress in fabricating, assembling and evaluating the basic microfactory modules.
