Vol 2 Chapter 1861: 3 keys

Of course, in theory, we can completely adjust the wearer's feel to no strength. In other words, the wearer can hold the ammo box without feeling the weight at all, just like holding a ball of air.

However, in this case, mistakes can easily occur, and the wearer will ignore the object he is carrying, causing some dangerous situations. Therefore, we will still appropriately make the wearer feel a certain weight, and it does not need to be too heavy, and the wearer will not feel tired while feeling the weight of the object. "

This drive system and pneumatic assist system can be introduced together. Wu Hao introduced to the crowd: "In this light mechanical exoskeleton power system, there are many drive systems and pneumatic power systems.

These two systems can be regarded as the active joints and muscle tissue on the human body. Of course, the joints on this light mechanical exoskeleton power system are more complex than the key to the human body.

In addition to the special force bearing, this set of joints also has a large torque maglev motor independently developed by us, as well as a reliable speed change system.

It is with this complex joint drive system that the excellent flexibility and maneuverability of this lightweight mechanical exoskeleton power system can be supported.

In addition, according to the different joints of various parts of the human body, the joint drive system on the light mechanical exoskeleton power system is also different. For example, the joint system on the limbs is different from the spine joint drive system on the trunk core support system.

Including the wrist joints and the miniature drive joints on the gloves, so many joints need to operate flexibly and be able to coordinate and unify. This technical difficulty is not something that everyone can do.

In addition to this joint drive system, supporting the movement of this lightweight mechanical exoskeleton power system is a pneumatic power system distributed throughout the body, or it can be called a very apt name, artificial muscle system.

Everyone knows the working principle of muscles. Movement is controlled by relaxation and contraction. This is also the principle of this pneumatic assist system. It controls the movement of various parts of the light mechanical exoskeleton assist system by rapidly inflating and deflating.

Otherwise, it is difficult to support the light mechanical exoskeleton power system with the joint drive system alone to drive the entire wearer and the weight on his back for rapid excitement, such as running, jumping, long jumping, etc., all of which require this pneumatic power system to generate power instantly. Just do it.

In addition, if you just picked up the ammunition box, you have to have this pneumatic power system to operate, otherwise it is difficult for these joint drive systems to carry such a large weight. "

Speaking of this, Wu Hao said to the leader who was wearing this lightweight mechanical exoskeleton power assist system: "Try punching, try harder."

Having said that, Wu Hao asked two soldiers wearing heavy mechanical exoskeleton-assisted protective armor to pick up a wooden board about five centimeters away. This plank is not the thin plank used in Taekwondo, but a solid plank.

Looking at this target, the leader walked in front of the plank, clenched his fists and prepared to strike, but he was a little scared.

It's okay, don't worry, with this exoskeleton support system protecting you, you can't be hurt. Wu Hao smiled and comforted.

Well, the leader nodded, then clenched his fists and made a slight gesture twice, then hit the target with all his strength. I saw a snap, and the wooden board broke, but it was not completely broken, but bent into a hundred and twenty degrees from the part where it was hit.

What does it feel like? Wu Hao asked with a smile.

The leader shook his arm, and then smiled at Wu Hao: "The fist doesn't hurt, it just feels like the arm has been shaken hard, and it's a little loose."

Wu Hao nodded and smiled: "It's normal, it's because you haven't undergone adaptive training, so you stretched your arm muscles when you punched quickly. It's fine, just recover for two days.

When you punched the plank quickly just now, the motion follow control system captured the strength of your arm swing and punch, and then controlled the exoskeleton assist system worn on the arm and hand to assist. In this way, you just threw your fist with such a fast speed that it produced such a force that it broke the plank.

The same goes for high jumps and long jumps, the air-assist system provides extra strength to the wearer's limbs, enabling them to jump higher, jump farther, and throw more favorable fists.

One of these technologies is joints, which is how this lightweight mechanical exoskeleton assist system knows the wearer's limb movements and makes just the right "response".

This requires a very clever control system, which is the motion following control system.

To put it simply, this is a set that can sense the wearer's limb movement and convert the wearer's limb movement signals into corresponding control signals and transmit them to the joint drive system and pneumatic assist system distributed in various parts of the motion following control system. .

In order to realize the real-time perception of the wearer's limb movements, we have arranged various sensors in various parts of this lightweight mechanical exoskeleton power assist system.

There is a sensor specially designed to sense the strength of the wearer's muscle contraction~www.readwn.com~, so that the strength of the wearer's force can be sensed, thereby controlling the pneumatic assist system in the corresponding position.

There are also spatial positioning sensors arranged in various joints, which can sense the parts of the wearer's limbs in real time, so as to control the light-weight mechanical exoskeleton power system to make corresponding movements.

In fact, this motion following control system is not so magical. Many exoskeleton systems also have corresponding systems, but the performance of each system is uneven.

There are three keys to determining the quality of these motion-following control systems. The first one is the perceived control accuracy. This system needs to acutely feel the slight movements made by the limbs and respond accordingly, so that the wearer will feel comfortable when moving, and can flexibly do various difficult movements.

The second key is the speed of response, whether the sensor can quickly sense the movement of the wearer's limb and quickly generate control signals to control the movement of the lightweight mechanical exoskeleton. If the reaction speed is too slow, it will greatly limit the flexibility of the wearer's activities, making the wearer feel restrained and uncomfortable, causing problems such as movement delay and sluggishness, which are undoubtedly fatal on the fierce battlefield.

The third key is reliability. How to ensure the safety and reliability of this motion following control system, to ensure that it can accurately and quickly perceive and transmit every control signal, this is whether this lightweight mechanical exoskeleton assist system can greatly improve The key to scale applications.

If there are frequent errors or downtime, then this light mechanical exoskeleton power assist system will naturally not be able to be used on a large scale, and it is naturally even less likely that troops will be deployed and put into battle.

Otherwise, on the battlefield, in addition to problems at the critical moment of the battle, this is very deadly. "
