Chapter 251

"The robot's walking path consists of straight segments and arcs, where the arc is the robot's turning path. The robot cannot make a curved line, and the turning path consists of a segment of arcs tangent to a straight path, or two or more tangent arc paths!"

In this case, when the robot turns, the maximum turning speed is v=v(ρ)=v0/1+e^(10-0.1ρ^2), and ρ is the turning radius. If this speed is exceeded, the robot will roll over. ”

“...... The last step is to establish a mathematical model of the shortest path and the shortest time path for the robot to avoid obstacles from one point in the area to another!"

Ma Zhengxuan turned his head and handed over the calculated data and trajectory equation to Bi Qi.

"Next, leave it to me!" Bizzi made an OK gesture.

Biqi opened the Matlab software on the computer and began mathematical modeling.

As the winner of the O Award of Meisai, Bi Qi's modeling level naturally does not need to be elaborated too much.

In the eyes of everyone, I saw Bi Qi as if he didn't need to think, putting his ten fingers on the keyboard with both hands, and typing data with a snap.

A model of the trajectory motion of the robot in an obstacle was gradually perfected in the hands of Bizzie.

Everyone in the robot team standing behind Bi Qi looked at it with brilliant eyes.

The rough boy from the mechanical academy glanced appreciatively at the plaid shirt boy next to him.

The meaning seems to say,

"Amazing, I found two great gods in the mathematics department!"

Feeling the sight of his teammates next to him, the plaid shirt boy secretly smiled bitterly in his heart.

If I say now that these two great gods of mathematics in your eyes are actually freshman students, do you believe it?

To tell the truth, the plaid shirt boy really didn't expect that Bi Qi and Ma Zhengxuan would be so relaxed now.

thought that this problem would make Bi Qi and Ma Zhengxuan retreat.

Because no matter how you look at it, such a problem that involves a lot of mathematical expertise and modeling knowledge is not like two first-year students can solve.

But the reality is ......

It seems that this problem is nothing to these two people.

Are these two really freshmen?

Even the plaid shirt boy was suspicious.

He looked down again at Bi Qi, whose fingers were about to appear on the keyboard, and the corners of his mouth twitched.

This proficiency, no matter how you look at it, doesn't look like a freshman student!

The plaid shirt boy's brow furrowed deeper and deeper.

............

Mathematical modeling is quite a chore.

But with the cooperation of Ma Zhengxuan and Bi Qi, everything seems extremely easy.

An hour later, Biqi took his fingers off the keyboard, exhaled lightly, and leaned back in his chair.

"That's it!"

Bi Qi's voice made several people who were napping with their chins on a table next to them instantly wake up.

Then, several people quickly came to Biqi's side.

"Classmate, is it really done?"

"Of course, you see!"

Bizzy taps the space bar, and on the screen, a block representing a robot moves across a map full of obstacles.

From the start point to the end point, a track path marked with a red line is left.

"That's the shortest time path you want. Biqi put his hands behind his head and said to everyone.

Glancing at the trajectory route map displayed on the computer screen, several members of the robot team glanced at each other, and there was joy in their eyes.

The obstacle map they just gave Biqi is a sample map attached to the organizing committee's document.

On the sample map given, the organizing committee also marked the track route that represented the standard answer.

And the route of the standard answer is exactly the same as the one marked with red lines displayed on the computer screen today!

What does this mean?

It means that these two students from the Department of Mathematics are really capable!

"Student Bi, classmate Ma, join us!" The rugged boy from the Mechanical Academy stared at Bi Qi and Ma Zhengxuan with fiery eyes.

In the main competition of the National Robot Competition, the obstacle map is definitely not the one in the example, it will definitely be a new obstacle map.

But it doesn't matter, as long as Bi Qi and Ma Zhengxuan are invited into their team, these are all fine.

Facing the fiery gaze of the rugged boy, Bi Qi laughed dryly, "I'm sorry, we still have a lot of books to read, I'm afraid we don't have time." ”

The rough boy was anxious, "But the map is not this one during the game, without you, we can only be in a hurry!"

"Don't worry about that. Bi Qi smiled slightly, "When the time comes, you only need to bring me this mathematical model over." ”

"Establish a coordinate system at the starting point of the obstacle map, and input the coordinates of the location of the obstacle into this program, and you can automatically calculate a track path that takes the shortest time!"

"So, whether we go or not, the effect is the same. ”

The rugged boy's eyes widened, "Really?"

Bi Qi shrugged his shoulders and said with a smile, "If you don't believe me, you can try." ”

A few people tried it with a skeptical attitude.

Sure enough, as Bizzy said, the mathematical model built by Bizzy only needs to input the coordinates of obstacles to automatically calculate an optimal route.

It's a completely brainless fool's operation.

Everyone looked at Bi Qi with a faint admiration in their eyes.

However, this strengthened everyone's desire to let Bi Qi and Ma Zhengxuan join their team.

In the end, Bi Qi and Ma Zhengxuan still compromised.

But with this set of procedures, there is no need for two people to play in the main competition, so Bi Qi and Ma Zhengxuan are just a name in this robot team.

To put it simply, if the robot team achieves good results in the national robot competition, then this honor also has Bi Qi and Ma Zhengxuan.

"Why don't you go to dinner together in the evening?" the rough boy saw that Bi Qi and the two were leaving, so he said.

Bi Qi waved his hand and apologized for refusing, "I'm sorry, we have an appointment for dinner in the evening." ”

A look of loss flashed on the rough boy's face, and then he said with a look of indifference, "It's okay, then we'll make an appointment next time, in short, thank you very much for your help this time!"

"That's so polite, since we are also part of your team now, then we should contribute. Bizzie snorted and said.

After finishing speaking, Bi Qi took Ma Zhengxuan and waved away.

The rough boy looked at Bi Qi and Ma Zhengxuan and closed the door and left, then turned his head and glanced at the plaid shirt boy beside him, "Zheng Jie, where did these two great gods of the mathematics department get invited?"

The plaid shirt boy told the truth, "The library happened to come across it." ”

The rough boy then asked, "Then do you know where these two great gods live, I remember that the fourth and fifth floors of the graduate student apartment were lived by graduate students from the School of Mathematics." ”

"No, they live in undergraduate dorms. ”

"Huh?"

"Would you believe that these two gods you are talking about are actually first-year math students?" said the plaid shirt boy with a wry smile.

"How so?!" the rugged boy's eyes widened.
