First of all, metal boots, the power exoskeleton is not too high for the shoe part, only need to allow the weight of the whole body to be transmitted to the earth through the exoskeleton, but the boots can not be too hard, they can be bent, so that the foot joints can move freely. Considering the battle to be encountered on the continent of Akara, Lin Wen shaped the boots as knee-length boots.

Lin Wen envisioned the sole itself as a metal plate, adding a shaft at the base of the toe so that the sole could be bent so that it would not interfere with walking. Then there is the upper, this layer of material is made of chain mail material, which is inherently soft, and comfort and flexibility can be guaranteed. Next is the girdle of the boot, which may also be called a shin armor.

The shin armor is attached to the sole of the shoe and uses rounded joints to ensure freedom of movement of the foot. The tibia has a knee pad at the tip, the knee part of the exoskeleton is connected to the knee pad, and the exoskeleton of the calf part is directly embedded in the shin carapace. In this way, the force generated by the weight when walking and running is transmitted to the shin armor through the exoskeleton skeleton, which then transmits the shin armor to the sole, and the sole to the ground.

Feeling that this design should be feasible, Lin Wen first gathered away the stack of design drawings in his hand and categorized them, then drew a model of his body on a blank piece of paper, and drew the expected knee-high boots on the calf. This drawing is used to preview the effect after the design is completed, and Lin Wen doesn't want to look like a monster after wearing the power exoskeleton he made.

After the boots were generally designed, Lin Wen began to add details, such as a layer of metal rubber attached to the sole to reduce the noise caused by walking and enhance friction, and the inner layer of the boot with a canvas or leather lining to keep it comfortable. By the time all the details of the boots were designed, Lin Wen had already used more than ten blank sheets of paper.

It's not easy to make a design, Lin Wen rubbed his eyes, took out a new piece of white paper and began to write, draw, and draw.

Next up are the shorts. Because when wearing a powered exoskeleton. He is wearing a shadow shark skin lining similar to a wetsuit. This inner lining will be tightly attached to the body, so the lower body sometimes looks bulging, Lin Wen doesn't want to be embarrassed because of this aspect, so a pair of shorts that can not only cover shame, but also protect the vital point.

The chain mail material is still chosen, and the length of the shorts is from the hip bone to the base of the thigh. A triangular steel plate should be added in the middle, after all, this protection is very important. The hip part of the exoskeleton is fixed on both sides of the metal shorts, and the double joint cross design is adopted, after all, the human thigh can not only move back and forth but also move left and right, and the exoskeleton cannot be used to restrain the user, but only the longitudinal joints use afterburner joints.

That's pretty much the way the shorts are designed, and as a supplementary detail, you can add secondary weapon slots to the exoskeletons on both sides, and pin a pistol or something. Easy to access in battle.

Then there is the breastplate, after all, Lin Wen is taking the agile route, the breastplate can be had, but it cannot affect the flexibility of the body, so the position of the breastplate can only be from above the xiphoid process of the ribs to below the collarbone, mainly to protect the heart and lungs. For the cuirass, Lin Wen didn't plan to use the whole metal plate, after all, this thing was not comfortable to wear at all. In this regard, Lin Wen intends to adopt the design of body armor on earth. A tight-fitting vest with a sandwich velcro with a metal insert plate inside. Of course, the metal plate is not a single piece, but 8 small pieces together, and this design is very flexible and will not hurt itself.

At the same time, the posterior wall of the cuirass can also fix the spine part of the exoskeleton, and on the vertebrae of the exoskeleton, there is also a small backpack composed of the exoskeleton's energy system and jet system, which can provide high jumps. Slow speed and other functions.

Then there is the helmet, Lin Wen thought about it for a long time and decided to use a pair of engineering glasses with the ability to highlight targets, night vision, ballistic calculation ability and other functions as the main body, the shape is like the laser eye in the X-Men. The glasses can then be fitted with a helmet armor module, which can be sealed with a shadow shark skin liner when fully assembled to ensure that the user can be protected in toxic environments, and the helmet must have an underwater breathing apparatus inside.

Then the last is the arm, the hands are the most flexible part of the person, the arm itself has a lot of joints, and many joints have a very wide range of motion, so the production of the exoskeleton arm part is very difficult.

In view of the fact that the human shoulder joint is a typical ball-and-socket joint, the shoulder part of the exoskeleton must also have a very large range of motion, and at the same time, there must be a booster device, so the shoulder part of the exoskeleton needs to use a spherical joint, but because of the shape of the spherical joint, it cannot fit the human body, so the starting point of the shoulder part of the exoskeleton should be in the middle of the vertebrae, Lin Wen designed an "L" structure here, from the center of the spine to the back of the scapula and the humerus of the exoskeleton is connected, Such a small structure is enough to use three spherical joints, which can be regarded as the most complicated place outside of the hand. And this piece can also be added to the shoulder armor, which is not only beautiful, but also can play a fixed role in the exoskeleton. There is an elbow brace at the elbow area, and the elbow joint of the exoskeleton is fixed to the elbow brace, which is connected to the exoskeleton joint structure behind the shoulder blade by the exoskeleton humeral part.

Then there is the forearm structure, because the human forearm can be rotated, so the forearm part of the exoskeleton cannot fit perfectly on the body. For this situation, Lin Wen got along with a solution - add a metal ring to the end of the skeleton of the exoskeleton forearm, and there is a sliding track inside the metal ring. In this way, only the wrist strap needs to be armed, and there is a bracket on the outside of the wristband that fits into the track of the metal ring, so that the rotation of the forearm is unhindered.

Finally, there is the palm part, Lin Wen plans to use chain mail gloves directly, the gloves are connected to the wrist guard, and the wrist joints, including each knuckle, are assisted by small power-assisted mechanical joints.

After the last stroke, Lin Wen dropped the quill in his hand and let out a long breath, in order to draw this drawing, Lin Wen had been busy for two whole days.

Putting away all the drawings that were almost piled up around the mountain, Lin Wen took the preview drawings and looked at them carefully, on the whole, the design was not bad, and the villain on the paper looked like a future soldier, full of science fiction.

Now that the drawings have been drawn, it's time to make the model. For something as complex as an exoskeleton, even if Lin Wen has mastered the engineering of the craftsman, he can't make a physical object directly from the drawings step by step, he must first make a one-to-one model to scrutinize every detail of the exoskeleton, after all, these details are related to life and death, and they must not be sloppy.
