外文翻译--工业机器人在颗粒包装机中的应用(编辑修改稿)内容摘要：

robot is a reprogrammable, multifunctional manipulator designed to move parts, materials, tools, or special devices through variable programmed motions for the performance of a variety of different task. This basic definition leads to other definitions, presented in the following paragraphs, that give a plete picture of a robotic system. 2. Preprogrammed locations are paths that the robot must follow to acplish work. At some of these locations, the robot will stop and perform some opertion ,such as assembly of parts, spray painting, or welding. These preprogrammed locations are stored in the robot’s memory and are recalled later for continuous poeration. Furthermore, these preprogrammed locations, as well as other program data, can be changed later as the work requirements change. Thus, with regard to this programming feature, an industrial robot is very much like a puter, where data can be stored and later recalled and edited. 3. The manipulator is the arm of the robot. It allows the robot to bend, and twist. This movement is provided by the manipulator’s axes, also called the degrees of freedom of the robot. A robot can have 3 to 16 axes. The term degrees of freedom will always relate to the number of axes found on robot. tooling and grippers are not part of the robotic system itself。 rather, they are attachments that fit on the end of the robot’s arm. These attachments connected to the end of the robot’s arm allow the robot to lift parts, s potweld, paint. arcweld, drill, deburr, and do a variety of tasks, depending on what is required of the robot. robotic system can also control the work cell of the operating robot. The work cell of the robot is the total environment in which the robot must perform its task. Included within this cell may be the controller ,the robot manipulator, a work table, safety features, or a conveyor. All the equipment that is required in order for the robot to do its job is included in the work cell. In addition ,signals from outside devices can municate with the robot in order to tell the robot when it should assemble parts, pick up parts, or unload parts to a conveyor. The robotic system has three basic ponents: the manipulator, the controller, and the power . Manipulator The manipulator, which does the physical work of the robotic system, consists of two sections: the mechanical section and the attached appendage. The manipulator also has a base to which the appendages are attached . The base of the manipulator is usually fixed to the work。
