4. Developing Core Design and Build Skills | 培养核心设计与建造技能

The heart of any competition is turning an idea into a working model. Practise the ‘Design – Build – Test – Improve’ cycle as often as you can. Start by sketching multiple solutions, labelling the parts and listing the materials. Then construct a simple prototype using cardboard, plastic strips, or craft wood before moving to tougher materials.

任何竞赛的核心都是将想法转化为可用的模型。尽可能多地练习“设计—搭建—测试—改进”这个循环。开始时要多画几种方案草图，标出零件并列出材料。然后用纸板、塑料条或手工木料搭建简单原型，过渡到更坚固的材料。

Learn to use basic tools safely: a junior hacksaw, a bench hook, a glue gun, and a ruler are your first engineering kit. Accurate marking and measuring directly affect how well your model performs. Even a 1 mm error can make a robot veer off course.

学会安全使用基本工具：手弓锯、靠山、热熔胶枪和直尺就是你的第一套工程工具包。精确的划线测量直接影响模型的性能，哪怕1毫米的误差都可能让机器人偏离方向。

5. Mastering Simple Machines and Mechanisms | 掌握简单机械与机构

Mechanisms are everywhere in competition engineering. Levers change the direction and size of a force. Pulleys can lift heavier loads with less effort. Gears can increase speed or torque. Understanding mechanical advantage is key – for example, the formula

Mechanical Advantage = Load / Effort

helps you predict whether your design will give enough force to pick up a game object. Practise calculating gear ratios using tooth counts: if a driver gear has 8 teeth and the driven gear has 24 teeth, the ratio is 3:1, and speed is reduced while torque is increased.

机构在竞赛工程中无处不在。杠杆能改变力的方向和大小；滑轮可以用较小的力提起较重的物体；齿轮能增加速度或扭矩。理解机械增益至关重要——例如公式

机械增益 = 负载 / 施力

可以帮助你预判设计是否能提供足够的力量抓取比赛物件。练习用齿数计算齿轮比：如果主动轮8齿、从动轮24齿，传动比为3:1，速度降低而扭矩增大。

6. Introduction to Electronics and Circuits | 电子与电路入门

Most modern competitions expect you to wire sensors, motors, and LEDs. Your SQA course teaches you about conductors, insulators, switches, and simple series circuits. Extend this by learning how to use a breadboard and read a basic circuit diagram. A typical sensor circuit uses a 5 V supply, a resistor, and a photoresistor to detect light levels.

多数现代竞赛都要求你连接传感器、马达和LED。SQA课程会教你导体、绝缘体、开关以及简单的串联电路。可以进一步学习使用面包板和读懂基础电路图。一个典型的传感器电路使用5 V电源、一个电阻和一个光敏电阻来检测光线水平。

Use colour codes to identify resistor values. For example, a resistor with bands brown-black-red has a value of 1 kΩ (1000 Ω). Always double‑check polarity when connecting LEDs: the longer leg (anode) goes to positive, and a current‑limiting resistor must be used.

用色码识别电阻值。例如，色环为棕‑黑‑红的电阻值为1 kΩ（1000 Ω）。连接LED时务必检查极性：较长脚（阳极）接正极，而且要串联限流电阻。

7. Programming Basics for Engineering Tasks | 工程任务中的编程基础

Even if you are just starting, block‑based coding environments like Scratch or VEXcode are perfect for competition robots. Learn to use loops, conditional statements (if‑then‑else), and sensor blocks. A simple autonomous routine might look like:

即使你刚开始学习，Scratch或VEXcode等积木式编程环境也完全适合竞赛机器人。要学会使用循环、条件语句（如果‑那么‑否则）和传感器模块。一个简单的自动运行程序可能如下：

1. Drive forward for 2 seconds → 2. If bumper pressed, stop and reverse → 3. Loop forever

1. 前进2秒 → 2. 如果触碰传感器被按下，停止并后退 → 3. 永远循环

Introduce variables to store sensor readings. For instance, a light sensor value can be stored as ‘brightness’ and used to decide whether to turn on a headlight. Keep code tidy by adding comments – judges often review your code logic.

引入变量来存储传感器读数。比如，将光线传感器值存为“亮度”，并用来决定是否打开车灯。添加注释保持代码整洁——评委经常审查你的代码逻辑。

8. Teamwork and Project Management | 团队合作与项目管理

International competitions are rarely solo efforts. You must divide roles such as builder, coder, documenter, and pit manager. Hold short daily stand‑up meetings to discuss progress and obstacles. Use a shared document or a simple Kanban board to track tasks: To Do, Doing, Done. This mirrors the project management approach used in professional engineering.

国际竞赛很少是个人努力。你需要分配分工，如建造手、程序员、文档记录员和维修区管理员。每天举行简短的站立会议，讨论进展和障碍。使用共享文档或简单的看板来追踪任务：待办、进行中、已完成。这反映了专业工程中的项目管理方式。

Listen to every teammate’s idea. A younger member’s sketch might solve a mechanism issue that an older member overlooked. Respect time limits and always have a backup plan if a part breaks during the event.

倾听每个队员的想法。低年级队员的一张草图可能解决高年级队员忽略的机构问题。遵守时间限制，并始终为比赛中零件损坏备好应急方案。

9. Documentation and Presentation Skills | 文档与演示技能

In competitions like F1 in Schools, you present an engineering portfolio and deliver a verbal pitch. Start a design journal early, recording every sketch, test result, and modification. Photograph your prototypes and annotate them with labels and measurements. Your journal should tell the story of why you changed a gear size or reinforced a weak joint.

在F1在学校等竞赛中，你需要展示工程档案并进行口头宣讲。尽早开始写设计日志，记录每一张草图、测试结果和修改。给原型拍照并标注说明和尺寸。日志应该讲述你为何改变齿轮尺寸或加固薄弱接头的故事。

Practise your presentation with clear, confident speech. Explain the problem, your design, the science behind it, and what you learned. Use simple technical terms and maintain eye contact. Many judges are impressed by teams that can explain the physics of their design.

练习演示时，表达要清晰自信。说明问题、设计方案、背后的科学原理以及学到的东西。使用简单技术术语并保持眼神交流。很多评委对能够解释自身设计物理原理的队伍印象深刻。

10. Safety and Ethical Engineering Practices | 安全与工程伦理实践

Every competition enforces strict safety rules. Wear safety goggles when cutting, sanding, or soldering. Tie back long hair and use a dust mask for fine particles. Know the location of the first‑aid kit, fire extinguisher, and emergency stop buttons on machinery. Safety is not just a rule; it is a professional habit engineers carry for life.

所有竞赛都有严格的安全规则。切割、打磨或焊接时佩戴护目镜。扎起长发，处理微细颗粒时戴上防尘口罩。熟悉急救箱、灭火器和设备紧急停止按钮的位置。安全不只是一条规定，更是工程师终身携带的职业习惯。

Ethically, always credit sources for any borrowed design or code snippet. Use sustainable materials where possible, and consider the environmental impact of your product. Engineering with integrity builds a reputation that lasts far beyond a single competition victory.

在伦理方面，借用任何设计或代码片段都应注明出处。尽可能使用可持续材料，并考虑产品的环境影响。秉持正直的工程理念所建立的信誉远超一次竞赛胜利。

11. Practice through Mini Challenges | 通过小型挑战赛练习

Set yourself weekly mini missions that mimic competition tasks. Build a bridge from 30 straws that can hold a book, or program a robot to follow a black line without leaving a square. Time‑constrained activities sharpen your problem‑solving under pressure. Keep a score sheet and try to beat your personal best.

给自己设定每周一次模仿竞赛任务的小使命。用30根吸管搭建一座能承重一本书的桥，或者编程让机器人在方块内沿黑线行走。限时活动能提升你在压力下解决问题的能力。制作记分表并努力超越自己的最佳成绩。

• Straw tower challenge – tallest free‑standing tower wins
• Mousetrap car – vehicle powered only by a mousetrap spring
• Egg drop – protect an egg from a 2‑metre fall using paper and tape

• 吸管塔挑战 – 最高的独立塔获胜
• 捕鼠夹小车 – 仅靠捕鼠夹弹簧驱动的车辆
• 护蛋行动 – 用纸和胶带保护鸡蛋从2米高处坠落不碎

Post your results in a team channel and ask for feedback. These mini challenges mirror the resilience needed at international events.

在团队频道发布成果并征求反馈。这些小型挑战是国际赛事所需韧性的缩影。

12. Resources and Further Learning | 资源与进阶学习

Build a personal library of reliable engineering sources. Websites such as the Institution of Engineering and Technology (IET), BBC Bitesize Design & Technology, and the official VEX or F1 in Schools hubs offer tutorials and past challenges. YouTube channels like ‘SparkFun Electronics’ and ‘Simple Machines’ break down concepts visually.

建立个人的可靠工程资源库。像英国工程技术学会（IET）、BBC Bitesize设计与技术以及VEX或F1在学校的官方中心均提供教程和往期挑战。SparkFun Electronics和Simple Machines等YouTube频道能以可视化的方式讲解概念。

Keep a dedicated notebook for new mechanics, circuits, and code snippets. Join an engineering club at school or start one. Most importantly, always stay curious: ask why a shape is strong, how a motor changes speed, or what makes a material springy. Every question brings you closer to competition success.

准备一本专用笔记本，记录新机构、新电路和代码片段。参加或创立学校工程社团。最重要的是，永远保持好奇：问为什么某种形状坚固、马达如何变速、什么使材料具有弹性。每一个问题都会让你更接近竞赛成功。
