1. What Is Automation? | 什么是自动化？

Automation involves using computers and control systems to operate machines or processes with minimal human input. A typical automated system collects data from sensors, processes it in a computer, and then sends signals to actuators to make something happen. Common examples include automatic traffic lights, washing machines and industrial production lines.

自动化是指利用计算机和控制系统来操作机器或流程，只需最少的人工输入。一个典型的自动化系统从传感器收集数据，在计算机中处理，然后向执行器发送信号以触发行动。常见的例子包括自动交通信号灯、洗衣机和工业生产流水线。

Some automated systems are fixed, meaning they carry out the same repetitive action every time. Other systems are programmable, so the sequence of operations can be changed. This flexibility makes modern automation suitable for many tasks, from packing goods to controlling a car engine.

有些自动化系统是固定的，意味着它们每次都执行同样的重复动作。另一些系统是可编程的，因此操作序列可以改变。这种灵活性使现代自动化适用于许多任务，从包装货物到控制汽车发动机。

2. Why Automate? | 为什么要自动化？

There are several important reasons why organisations choose to use automation rather than human workers.

组织选择使用自动化而非人工操作，有几个重要原因。

• Consistency: automated systems perform tasks in the same way each time, reducing errors.

  一致性：自动化系统每次都以相同方式执行任务，从而减少错误。

• Speed and productivity: machines can often work faster than humans and do not need breaks.

  速度和生产率：机器通常比人类工作更快，而且不需要休息。

• Safety: automation can handle dangerous jobs such as nuclear waste handling, deep-sea exploration or bomb disposal.

  安全性：自动化可以完成危险工作，例如核废料处理、深海勘探或拆弹。

• Lower long-term costs: although automation may be expensive to install, it can reduce the running costs over time.

  降低长期成本：虽然自动化安装成本可能很高，但长期来看可以降低运营成本。

3. Robotics | 机器人技术

A robot is a programmable machine that can sense its surroundings, process information and carry out physical actions. Robots are often used in factories to weld, paint, assemble or move objects. In hospitals, surgical robots help doctors perform precise operations, while exploration robots can work in space or underwater.

机器人是一种可编程机器，能够感知周围环境、处理信息并执行物理动作。机器人常用于工厂中焊接、喷漆、装配或搬运物体。在医院里，手术机器人帮助医生进行精细操作，而探索机器人可以在太空或水下工作。

A robot usually has several key components. Sensors collect input from the environment, such as light, sound, temperature or distance. The processor runs a program and decides what to do. Actuators, such as motors and pistons, produce movement. The power supply provides energy, and the chassis or body holds everything together.

机器人通常由几个关键部件组成。传感器收集环境输入，如光线、声音、温度或距离。处理器运行程序并决定该做什么。执行器（如电动机和活塞）产生运动。电源提供能量，机架或机身将各部分连接在一起。

4. Artificial Intelligence (AI) | 人工智能

Artificial intelligence is the branch of computer science that focuses on building systems able to behave in ways that would usually require human intelligence. These abilities include understanding language, recognising images, making decisions, solving problems and learning from experience.

人工智能是计算机科学的一个分支，专注于构建能够以通常需要人类智能的方式行为的系统。这些能力包括理解语言、识别图像、做出决策、解决问题以及从经验中学习。

Automation and AI are not exactly the same. Automation usually follows a fixed set of instructions and cannot respond to unexpected situations. AI systems can adapt, find patterns and improve over time. However, many modern automated systems combine both automation and AI to make them more intelligent and flexible.

自动化与人工智能并不完全相同。自动化通常遵循一组固定的指令，无法应对意外情况。AI 系统能够适应、发现模式并随着时间改进。然而，许多现代自动化系统将自动化和人工智能结合在一起，使其更加智能和灵活。

5. Machine Learning | 机器学习

Machine learning is a type of artificial intelligence in which a computer learns from data rather than following explicitly programmed rules. The system is given a large training dataset, examines patterns in the data, and builds a model that can make predictions on new information.

机器学习是一种人工智能类型，计算机从数据中学习，而不是遵循显式编程的规则。系统会获得一个大型训练数据集，分析数据中的模式，并建立一个模型，用它对新的信息做出预测。

For example, an email spam filter can be trained on thousands of emails. It learns which words and patterns are common in spam messages. Then it uses this knowledge to classify new emails as spam or not spam.

例如，垃圾邮件过滤器可以用成千上万封电子邮件进行训练。它学习垃圾邮件中常见的单词和模式，然后利用这些知识将新邮件分类为垃圾邮件或非垃圾邮件。

A common machine learning technique is the neural network, which is inspired by neurons in the human brain. Neural networks contain layers of connected nodes, and each connection has a weight that changes as the system learns.

一种常见的机器学习技术是神经网络，它的灵感来自人脑中的神经元。神经网络包含多层相连的节点，每个连接都有一个权重，并随着系统学习而改变。

6. Expert Systems | 专家系统

An expert system is a computer program that mimics the decision-making ability of a human expert in a particular field. It contains knowledge and a set of rules, and it asks the user questions to reach a conclusion. Expert systems are used in medical diagnosis, credit scoring and mineral exploration.

专家系统是一种计算机程序，在特定领域模拟人类专家的决策能力。它包含知识和一组规则，并向用户提问以得出结论。专家系统用于医疗诊断、信用评估和矿产勘探。

There are several important parts of an expert system:

专家系统有几个重要组成部分：

• The knowledge base stores facts and rules about the topic.

  知识库存储有关该主题的事实和规则。

• The inference engine selects rules and applies them to the facts entered by the user.

  推理引擎选择规则并将它们应用于用户输入的事实。

• The user interface allows the user to answer questions and receive the system’s advice.

  用户界面允许用户回答问题并接收系统的建议。

• The explanation system tells the user how a conclusion was reached.

  解释系统告诉用户结论是如何得出的。

Rules in an expert system are often written as IF … THEN … statements. For example:

专家系统中的规则通常写成“如果……那么……”语句。例如：

IF patient has a fever AND a rash THEN suggest a possible infection

如果患者有发烧 AND 有皮疹 THEN 提示可能是感染

7. Natural Language Processing and Computer Vision | 自然语言处理与计算机视觉

Natural language processing allows computers to understand, interpret and respond to human language. Applications include speech-to-text, language translation, virtual assistants and chatbots. NLP uses grammar rules, dictionaries and machine learning to deal with real-world language variation.

自然语言处理使计算机能够理解、解释并响应人类语言。应用包括语音转文字、语言翻译、虚拟助手和聊天机器人。NLP 使用语法规则、词典和机器学习来处理真实世界中的语言变化。

Computer vision allows computers to see and process images. Facial recognition systems identify people by matching patterns in their face. Self-driving cars use computer vision to detect pedestrians, lane lines and traffic signs. Computer vision often relies on convolutional neural networks, a kind of machine learning model specialised for image data.

计算机视觉使计算机能够“看见”并处理图像。人脸识别系统通过匹配面部模式来识别人。自动驾驶汽车使用计算机视觉检测行人、车道线和交通标志。计算机视觉通常依赖卷积神经网络，这是一种专门处理图像数据的机器学习模型。

8. Autonomous Systems | 自主系统

Autonomous systems are automated systems that can make their own decisions without human intervention. They sense the world, process information using algorithms and AI, then take action. Examples include self-driving cars, autonomous drones and robots that explore other planets.

自主系统是无需人工干预即可自行做出决策的自动化系统。它们通过传感器感知世界，利用算法和 AI 处理信息，然后采取行动。例子包括自动驾驶汽车、自主无人机和探索其他星球的机器人。

An autonomous vehicle, for instance, uses cameras, radar and GPS as sensors. Its on-board computer builds a model of the surrounding traffic and decides when to brake, steer or accelerate. This kind of system must be highly reliable and is tested in many real-world situations before being used by the public.

例如，自动驾驶汽车使用摄像头、雷达和 GPS 作为传感器。其车载计算机构建周围交通状况的模型，并决定何时刹车、转向或加速。这类系统必须高度可靠，并且在向公众使用之前必须在许多真实环境中测试。

Another concern is who is responsible when an intelligent machine makes a wrong decision, for example during an autonomous vehicle accident. Therefore, governments and companies are creating ethical guidelines and regulations to ensure responsible use of AI.

另一个关注点是在智能机器做出错误决定时，例如自动驾驶汽车事故中，责任归属问题。因此，政府和公司正在制定道德准则和法规，以确保负责任地使用人工智能。
