Xu Chuan asked curiously: "How many test items are there in total?"

Xu Xiao thought for a while and replied: "There are a total of fifty-six basic tests and optional tests."

"In addition, there are also regulations on material stiffness testing, protection level testing, safety leakage inspections, etc. All added up..."

"Well, if we start with materials, there may be more than a hundred items."

On the side, Zheng Hai, who had been silently watching the experiment, suddenly asked: "Can I ask, what is the maximum load of this bionic mechanical leg?"

Xu Xiao replied without thinking: "The current critical load test for the mechanical leg is 573 kilograms. The single-leg load was obtained in an independent experiment, that is, an experiment without surgical insertion into the human body."

"Exceeding this load, the knee joint material will be damaged to a certain extent. If the load is exceeded, the material at the connection will be directly cracked, deformed, damaged, etc."

"As for the experimental tests that have been connected to the human body, considering the bone strength of the experimenters, we have only conducted load tests below 150 kilograms."

"To put it simply, when a bionic mechanical leg is used to stand on one leg, with the assistance of other equipment, it can bear a load of less than 150 kilograms, squat and stand up while bearing the weight of the human body itself.

Waiting for activities.”

"Is there any problem? Brother Zheng."

Zheng Hai thought for a while and said: "The operation of the mechanical legs requires external energy or electrical energy, right? For example, a battery? How long can it last?"

The critical load of a single body test is more than 500 kilograms, and the human body test of a single leg exceeds 150 kilograms. Plus the weight of an adult man, the load is at least more than 250 kilograms. If there are no restrictions on this mechanical leg,

The performance is a bit exaggerated.

This chapter is not over yet, please click on the next page to continue reading! Xu Xiao nodded and said: "Of course, this kind of bionic device is controlled by converting brain nerve signals into electrical signals, and it definitely requires external energy to support its movement.

, otherwise where does the energy come from?”

After a pause, she looked at the experimenter who was conducting the test, and then said: "Currently we are using two lithium-sulfur batteries as energy supply. Under normal activities, the arm can last for about 15 hours."

"Because the thighs bear more weight and require higher energy supply, they can only last about 8 hours."

"But it's quite convenient to replace the battery."

Xu Chuan glanced at Zheng Hai and asked curiously: "Do you have any ideas?"

Zheng Hai was silent for a moment, nodded and said: "There are indeed some, but let's wait until the test is completed."

Hearing this, Xu Chuan didn't think much. He turned his head and looked at the patients undergoing clinical trials, observing them carefully.

Soon, the problem Xu Xiao mentioned before appeared in this test experiment.

In the laboratory, collision detection testing is ongoing, which is an experiment in which the collision conditions of the robotic arm are artificially set to test whether the collision detection function is normal.

Something strange happened to the installed mechanical leg. When it was avoiding the foam stick swept out from the test equipment, its output force was so great that the moment balance between the two legs was instantly broken.

Under the feedback of the mechanical leg, the soldier who underwent the experiment flew out crookedly and fell to the ground as if jumping on one leg.

Seeing this scene, the staff on standby immediately went up to turn off the equipment and then helped him up.

Xu Xiao pursed her lips, sighed and said, "This is one of the problems I mentioned before. During activities, the signals transmitted from the brain-computer interface chip to the bionic robotic arm will be abnormal."

"Sometimes it may be enlarged, and sometimes it may be reduced, which will cause the originally normal movement to become unbalanced."

"Just like Jiang Yu just now, under the force of the uncontrolled mechanical legs, the whole person was pushed to 'fly' and lost his balance."

"This kind of problem occurs at uneven times, but the probability is quite high. This is also the problem that worries me the most."
