Real-time Servo Control using EtherCAT Master on Real-time Embedded Linux Extensions

In this paper, we present a real-time servo control application based on an open-source EtherCAT Master under two different real-time embedded Linux approaches, the fully preemptible kernel and Xenomai. The fully pre-emptible approach utilizes the native Linux kernel patched to support pre-emption of high-priority tasks at any time and protects critical sections with spin locks. On the contrary...

Immunoglobulin Structure Exhibits Control over CDR Motion

Motions of the IgG structure are evaluated using normal mode analysis of an elastic network model to detect hinges, the dominance of low frequency modes, and the most important internal motions. One question we seek to answer is whether or not IgG hinge motions facilitate antigen binding. We also evaluate the protein crystal and packing effects on the experimental temperature factors and disord...

Design of the 4-DOF Parallel Robot Control System Based on EtherCAT

This design includes both the hardware system and software system. The control system can not only achieve the motion control but also can realize simulation. Hardware system is constituted by Parallel Robot Body, Embedded IPC (Industrial Personal Computer), servo drive and motor system, EtherCAT module and I/O module and so on. Software system realized by the Automation software CODESYS, which...

Analysis of Grasping Motion Using a Virtual Prosthetic Control System

Electromyogram (EMG) signals can be measured from human muscles and can be used to anticipate movements. In fact, many researchers have tried to use these signals as an interface tool for a prosthetic hand. However, most of these studies focused on the discrimination performance of the EMG signals, and only discussed the control method for the prosthetic hand. Evaluation of the operating perfor...
