第十三章：建立基地——以机器人为主
为节约运输成本，初期投入10个集装箱的物资作为启动建设的基础。核心思想是用76个全能人形机器人，在到达火星后，利用零配件和3D打印，再组装制造一批重复劳动型机器人，再利用所有的人形机器人，结合火星上的现有材料，进行建筑物建设、金属冶炼、玻璃生产、塑料生产、太阳能光伏板制造等，其中集装箱本身可以用于改造成电热锅炉，用于冶炼金属等。具体初始投入包括76个人形机器人（约装满一个标准集装箱），上千套人形机器人的芯片（1个）、双目摄像头（1个）、机器人关节马达（28个，如波士顿动力公司的Atlas机器人约有28个），约装满2个标准集装箱。和上百台碳纤维3D打印机和混凝土3D打印机，约装满7个集装箱。76个人形机器人利用人形机器人核心套件，再结合碳纤维3D打印机，打印人形机器人的躯干手脚等，形成约1,000个人形机器人。这些人形机器人，又进行分工，形成生产工具生产、金属冶炼、玻璃生产、塑料生产、混凝土生产、建筑生产、太阳能板制作等生产线，形成20条以上生产线，同步生产各类产品，建造基地。一个集装箱堆放 76 台人形机器人一个集装箱可堆放的人形机器人数量：20英尺标准集装箱（20ft container）内部尺寸约5.9m×2.35m× 2.39m（长×宽×高），容积约33立方米。假设一个标准人形机器人的尺寸为身高1.8m、宽度（肩宽）0.6m、厚度0.4m，单个机器人体积约0.43立方米（考虑外部零件和实际占用空间）。将机器人横躺，堆叠起来堆放入集装箱，同时做好关节和外壳保护，可摆放约76台。碳纤维 3D 打印机碳纤维以其高强度、低密度、耐高温和抗腐蚀等优异性能闻名，是现代材料科学的明星材料之一。碳纤维的典型拉伸强度范围为3,500 ~ 6,000MPa（兆帕）。对比钢的拉伸强度约为400 ~ 700MPa，这意味着碳纤维的强度可达钢的5 ~ 10倍。碳纤维具有极高的强度－重量比，远高于钢和铝。碳纤维的密度：约1.6 g/cm³（钢约为7.8 g/cm³，铝约为2.7 g/cm³）。这使得碳纤维在强度上占据优势，同时保持轻质特性，是航空航天和汽车工业的首选材料。将来，将有一种将空气中二氧化碳转化为碳纤维的3D打印机。因二氧化碳（CO2）是高度稳定的分子，转化为碳纤维需要打破C = O双键并重新组装为碳原子链。这一过程第二部分：建立需要高效的催化剂、电能输入和通过高温碳化聚合物（如PAN，聚丙烯腈）制得，再利用3D打印技术直接沉积打印成型碳纤维，形成高强度、低重量的各种设备材料。火星混凝泥土 3D 打印机利用硫磺作为黏合剂，将火星泥土（风化层）和硫磺混合后加热并冷却，形成硫磺混凝土。具体技术步骤：从火星土壤中提取硫磺（火星土壤富含硫酸盐，提取后加热至140 ~ 150°C使其液化）。将火星土壤颗粒与液化硫磺按比例混合，倒入3D打印机喷头中，直接打印出大量的建筑物。
Chapter 13: Establishing Bases — Robot-Led
To save transportation costs, the initial investment consists of 10 containers of materials as the foundation for starting construction. The core idea is to use 76 versatile humanoid robots that, upon arriving on Mars, utilize spare parts and 3D printing to assemble and manufacture a batch of repetitive-labor robots. Then, using all the humanoid robots combined with existing materials on Mars, they carry out building construction, metal smelting, glass production, plastic production, solar photovoltaic panel manufacturing, and more. The containers themselves can be converted into electric boilers for smelting metals. The specific initial investment includes 76 humanoid robots (approximately filling one standard container), thousands of sets of humanoid robot chips (1 each), binocular cameras (1 each), and robot joint motors (28 each, similar to Boston Dynamics' Atlas robot which has approximately 28 joints), filling approximately 2 standard containers. Plus over 100 carbon fiber 3D printers and concrete 3D printers, filling approximately 7 containers. The 76 humanoid robots use humanoid robot core kits combined with carbon fiber 3D printers to print humanoid robot torsos, hands, and feet, forming approximately 1,000 humanoid robots. These humanoid robots are then divided into specialized teams, forming production lines for tool production, metal smelting, glass production, plastic production, concrete production, building construction, solar panel manufacturing, and more, creating over 20 production lines that simultaneously produce various products and build the base. One container holding 76 humanoid robots: The number of humanoid robots that can be stored in one container — a 20-foot standard container (20ft container) has internal dimensions of approximately 5.9m × 2.35m × 2.39m (length × width × height), with a volume of approximately 33 cubic meters. Assuming a standard humanoid robot has dimensions of 1.8m in height, 0.6m in width (shoulder width), and 0.4m in thickness, a single robot's volume is approximately 0.43 cubic meters (considering external parts and actual space occupied). By laying the robots horizontally and stacking them in the container while protecting joints and shells, approximately 76 units can be accommodated. Carbon fiber 3D printers: Carbon fiber is known for its excellent properties of high strength, low density, high temperature resistance, and corrosion resistance, making it one of the star materials in modern materials science. The typical tensile strength range of carbon fiber is 3,500 to 6,000 MPa (megapascals). For comparison, the tensile strength of steel is approximately 400 to 700 MPa, meaning carbon fiber's strength can be 5 to 10 times that of steel. Carbon fiber has an extremely high strength-to-weight ratio, far exceeding steel and aluminum. Carbon fiber density: approximately 1.6 g/cm³ (steel is approximately 7.8 g/cm³, aluminum is approximately 2.7 g/cm³). This gives carbon fiber a strength advantage while maintaining lightweight characteristics, making it the preferred material for aerospace and automotive industries. In the future, there will be a 3D printer that converts carbon dioxide from the air into carbon fiber. Since carbon dioxide (CO2) is a highly stable molecule, converting it into carbon fiber requires breaking the C=O double bonds and reassembling them into carbon atom chains. This process Part II: Establishment requires efficient catalysts, electrical energy input, and high-temperature carbonization of polymers (such as PAN, polyacrylonitrile), followed by direct deposition and printing using 3D printing technology to form carbon fiber, creating various high-strength, low-weight equipment materials. Mars concrete 3D printers: Using sulfur as a binder, mixing Mars soil (regolith) and sulfur, heating and cooling to form sulfur concrete. Specific technical steps: Extract sulfur from Martian soil (Mars soil is rich in sulfates; after extraction, heat to 140-150°C to liquefy). Mix Martian soil particles with liquefied sulfur in proportion, pour into 3D printer nozzles, and directly print large quantities of buildings.
