MMB Why is there a weapon system in Chapter 19?
Why is there a weapon system in Chapter 19?
As soon as the host finished speaking, Lu Feng pushed a flatbed cart from the shadows of the passageway onto the display stage.
He walked to the center of the venue, without taking a microphone or even glancing at the judges' panel.
The eyes of thousands of people in the audience were all fixed on this freshman, filled with mockery and impatience.
Lu Feng grabbed one corner of the black cloth with one hand and pulled it backward with force. The black cloth drew an arc in the air and landed on the wooden floor.
A set of disassembled, silver-gray mechanical components were exposed without reservation to the bright lights.
There are no fancy paint jobs; it's just the original color of the aluminum alloy after milling.
The breastplate, arm armor, and leg supports are hung on various nodes of the display rack.
The conversation on the judges' panel abruptly stopped. Was this for real?
The expert, who had just thrown down his pen, suddenly sat up straight, slammed his hands on the table, and stretched his neck forward.
He initially thought it was just a gimmick by a freshman, but the layman sees the spectacle, while the expert sees the real deal.
The precision of that mechanical structure's engagement cannot be achieved by simply buying a few open-source modules.
At the company representatives' table, DJI's HR representative pulled out a DSLR camera, pointed the lens at the stage, and frantically pressed the shutter button.
"Hurry up and take the picture!"
"No, is Lu Feng serious?" Zhou Mingyuan sat in the stands, his jaw almost dropping to his chest.
Zhao Pengfei gripped the back of the seat in front of him tightly with both hands, his fingernails scraping the plastic edge with a screeching sound.
"He spent a whole month alone in the lab just to make this thing?"
Li Hongde pushed up his gold-rimmed glasses. He didn't look at the cool armor shells; his gaze went past the breastplate and landed on the single-axis power assist mechanism on the leg.
Variable stiffness torsion springs, nonlinear dampers, and miniature speed reducers.
When these three things are combined, they form a typical strongly nonlinear vibration system.
Li Hongde's mind began to race.
If the high-frequency resonance problem is not solved, this system will fail immediately upon being powered on.
The fact that Lu Feng dared to bring it up shows that the multi-scale perturbation method has indeed been written into the control algorithm!
A layer of cold sweat seeped out from Li Hongde's back.
Just how much is in this kid's head?
Lu Feng, who was on stage, first introduced himself.
"Distinguished judges, teachers, and fellow students, hello everyone. I am Lu Feng from Class 1, Mechanical Engineering, 2012."
"My project is a wearable exoskeleton demonstration prototype."
He then walked to the support frame and removed the exoskeleton from his left leg.
"Click".
The buckle engages precisely.
Lu Feng moved extremely quickly, pulling at his waist with both hands, causing the support bars on both sides of his thighs to spring up and lock his hip joints.
Next, the right leg, the same movement, took less than five seconds.
He then picked up the breastplate and folded it in front of his chest.
The dovetail groove at the center line is smoothly inserted.
Finally, there's the arm armor.
Slip it onto your forearm, flip your wrist, and the quick-release buckle makes a crisp snapping sound.
The entire wearing process was completed without any unnecessary adjustments or pauses.
The electronic timer on the wall ticked, twenty-eight seconds.
The entire room fell silent.
The thousands of people forgot to breathe, only hearing the echoes of the machinery colliding on the stage.
Lu Feng stood in the center of the stage, dressed in silver-gray metallic armor, the mechanical texture and human lines blending perfectly.
He raised his right hand and pressed a red button on the side of his breastplate.
"Inspect the mech."
Lu Feng spoke, his voice carrying throughout the venue via the lavalier microphone.
The next second, a deep sound came from inside the breastplate.
"Self-test program initiated."
"The server system is operating normally."
"The energy management system outputs stable."
"The weapon system is in standby mode without error."
These few announcements sent the entire stadium into an uproar.
"Holy crap! A voice module!"
"He even integrated the electronic control system?"
"Wait, what did it just say? Weapon system?!"
The experts on the judging panel looked at each other, sweat beading on their foreheads.
In a mechanical innovation competition, you submit a weapon system?
BYD's technical director slapped his thigh, his face flushed with excitement.
Lu Feng ignored the commotion below the stage.
He stood with his legs slightly apart.
"Wear armor."
The instruction has been issued.
The faint hum of electricity instantly drowned out all the other noises in the room.
The miniature servo motors hidden inside the armor simultaneously activated, the side wings on both sides of the chest armor automatically retracted, perfectly conforming to the contours of Lu Feng's ribs, the gear sets at the leg joints meshed rapidly, and the power levers precisely adjusted the angle along the direction of the thigh muscles.
The linkage on the arm guard securely fixes the wrist brace in place.
The entire closing process took less than three seconds, without any hesitation.
It is conducted entirely based on human kinematics simulation.
This requires extremely high machining precision and variable stiffness control algorithms.
Li Hongde suddenly stood up, his knee hitting the back of the chair in front of him without him noticing.
He understood.
The theory of that multi-scale perturbation method was perfectly transformed by Lu Feng into a microcontroller.
By predicting deformation at the microsecond level, the motor torque can be adjusted in advance.
This is absolutely not something a freshman should touch!
"God... this is a monster!" Zhou Mingyuan covered his head, feeling that his worldview had been completely shattered.
He thought that Lu Feng was impressive for making a small car with an electric motor.
As a result, they actually handcrafted the mecha.
On the judges' panel, the experts from the Provincial Mechanical Engineering Society leaned forward, their hands on the table, staring intently at every joint of Lu Feng.
He tried to find even the slightest interference or misalignment.
No.
A flawless finished product is laid out before you.
You can't find the error.
Lu Feng on stage stretched his wrists.
He turned around and faced the empty side of the stage.
"Weapon system activated."
Upon hearing these six words, the judges in the front row were so startled that they opened their mouths.
"Damn, they actually have a weapon system."
Above the forearm armor, two cover plates slide open to the sides.
The internal mechanical structure is reassembled in a fraction of a second.
A dark gun barrel sprang out, pointing straight into the air.
The hearts of thousands of people in the stadium stopped beating at that moment.
Zhang Wei stared wide-eyed in the stands, dropping his potato chips all over the floor.
Lu Feng's forearm muscles tensed, triggering the built-in electromyography sensor.
"Bang!"
A blinding white light shot out from the gun barrel, accompanied by a strong smell of gunpowder.
The enormous recoil was transmitted through the gun barrel to the arm armor.
The nonlinear damper of the exoskeleton intervenes instantly.
Lu Feng's body barely moved, meaning this shot had virtually no recoil.
The efficiency of this shock absorption system is terrifying.
A blank shot.
Lu Feng fired a blank cannon made of a mixture of high-pressure gas and magnesium powder.
A full ten seconds passed.
Then a sound like the roof being ripped off erupted from inside the stadium.
"Awesome!!!"
The entire freshman contingent of the School of Mechanical Engineering went completely mad.
The boys screamed at the top of their lungs, while the girls frantically recorded videos with their phones.
The experts on the judging panel slumped in their chairs, panting heavily.
Do you have any nitroglycerin pills?
