机器人介绍工作原理英文版 Part of a robot.At the most basic level, the human body consists of five main components: Muscle system, used to move body structures Sensory system, used to receive information about the body and the surrounding environment. Energy source, used to provide energy for muscles and senses. The brain system is used to process sensory information and direct muscle movements. Of course, human beings still have some intangible characteristics, such as intelligence and morality, but on a purely physical level, this list is quite complete. The components of robots are very similar to those of humans. A typical robot has a movable body structure, a device similar to a motor, a sensing system, a power supply and a computer "brain" to control all these elements. In essence, robots are "animals" made by humans. They are machines that imitate human and animal behaviors. The term "Robot" in English comes from the Czech word robota, which is usually translated as "forced laborer". It is very appropriate to describe most robots. Robots in the world are mostly used for heavy repetitive manufacturing work. They are responsible for tasks that are very difficult, dangerous or boring for human beings. The most common manufacturing robot is the robot arm. A typical robot arm consists of seven metal parts, which are connected by six joints. The computer will rotate the stepping motor connected to each joint to control the robot (some large robotic arms use hydraulic or pneumatic systems). Unlike ordinary motors, stepping motors move precisely in increments. This enables the computer to move the robot arm accurately, and the robot arm can repeat the exact same action repeatedly. The robot motion sensor is used to ensure that it moves exactly the right amount. This industrial robot with six joints is very similar to a human arm. It has parts equivalent to shoulders, elbows and wrists. Its "shoulder" is usually mounted on a fixed base structure (rather than a moving body). This type of robot has six degrees of freedom, that is, it can rotate in six different directions. In contrast, the human arm has seven degrees of freedom. 本文来源：https://www.wddqw.com/doc/dab6ad7ce75c3b3567ec102de2bd960591c6d95e.html
