Mary, have you ever seen a robot before.
Yes, I have been to some robot exhibitions. There were many interesting robots. They could even talk with me.
And could you give a definition of robot?
Simply speaking, a robot is mechanical arms controlled by computer programs. What does an industrial robot system consist of?
Well, the industrial robot system consists of three components: the manipulator, the power supply and the computer.
Is an industrial robot good or bad for society, do you think?
In my opinion, it is good. It releases humans from performing boring work on a production line or uncomfortable and possibly dangerous work in factories. Reading Robots
Robotics is a general-purpose modern technology of programmable machine systems. 机器人学是可编程机器系统的现代通用技术。
Robot is a re-programmable, multifunctional mechanical manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions.
机器人是一种可重复的多功能操作器，其设计目的是通过多种程控运动来运送材料，零件，工具或者特殊装置。
Robots perform a flexible, but restricted, number of operations in computer-aided manufacturing processes. Various robots are quite simple mechanical machines that perform a dedicated task such as spot welding or assembly operations. Industrial Robots are found in a variety of locations including the automobile and manufacturing industries. However, robot technology is relatively new to the industrial scene.
机器人在计算机辅助制造中执行灵活多变、但是严格又数量众多的操作。 各种机器人是非常简单的机械设备，可以执行专门任务，如点焊或装配业务。 工业机器人用于各种不同的场合，包括汽车和制造业。 然而，机器人技术在工业现场是相对较新的。
According to its application, robots can be classified as industrial robots, agricultural robots, health care robots, space robots, intelligent robots and so on.
根据机器人的应用， 它可以分为工业机器人，农业机器人，医疗保健机器人，空间机器人和智能机器人等等。
