Reducing resource and energy are most important in the future as well as now. Extrusion of aluminum alloys used as materials for automotive industry in recent years studied abroad, and also one of many important resources are used. Especially, it is necessary to resolve such problems like that lighter weight of car and stability. Unlike conventional Extrusion, PLC and Extruder are controlled by PC produce a variable cross sectional shape. Processing speed control and 3-axis control through extrusion ratio can be made real time control of variable geometry. Depending of the processing speed can be controlled and set up extrusion of the product in real time to adapt to the changes it can produce a uniform quality.

Three dimensional (3D) position determination and motion recognition using a 3D depth sensor camera are applied to a developed penguin-shaped robot, and its validity and closeness are investigated. The robot is equipped with an Asus Xtion Pro Live as a 3D depth camera, and a sound module. Using the skeleton information from the motion recognition data extracted from the camera, the robot is controlled so as to follow the typical three mode-reactions formed by the operator’s gestures. In this study, the extraction of skeleton joint information using the 3D depth camera is introduced, and the tracking performance of the operator’s motions is explained.
