Development of a articulated robot with the direct-teaching function

The industrial robot is widly used in the field of car manufacturing, welding, wafer handling, object transfering and so on. Each application needs its own important properties such as high precision, high payload, compact size and so on. Then, all of industrial robots need the fixed-time control property commonly. The ethercat is a highly flexible EtherCAT network protocol that is developing at a rapid rate and growing at an even faster clip. It is extention of conventional ethernet with a high speed communication and simple wiring characteristic. With the ethercat, the implementation of the industrial robot is more easier. Here, the implementation of the industrial robot with the function of the direct teaching is described. That robot is controlled through the ethercat communication between the ethercat master in PC and ethercat slaves developed for this robot.
