Five minutes later.

Liu Chi led Ye Yuxin to the square downstairs and looked around. There happened to be a road here that was suitable for testing.

There is a cement road about 50 meters long on flat ground. After that, there is a slope. Then there is a gravel road. At the end, there is a bumpy mud road of more than ten meters.

Great for testing!

"Let's go and test it on this road, it's just right." Liu Chi tilted his head towards the direction of the test road and said to Ye Yuxin.

Ye Yuxin looked along the path to the end. The whole path was about 200 meters long. She nodded and asked in confusion, "Well, how do we test it?"

Liu Chi fiddled with the robot while explaining, "This robot has two modes: 1: rush to the finish line at the fastest speed; 2: when there is interference, turn on the defense mode, which is to prioritize avoiding some human interference and reach the finish line at the fastest speed."

"Then let's try it." Ye Yuxin blinked, still looking confused. Anyway, she didn't understand why he gave up the research in the end. She glanced at the tablet in Liu Chi's hand and asked, "Is this tablet the control program?"

"Yes, let's start." Liu Chi carefully put the robot on the ground. After stabilizing it, he used the navigation on the tablet to set the route. He glanced at Ye Yuxin who was looking expectant at the side and said, "Then I'll start. Follow this path and I'll test the first mode first."

"Um..."

Liu Chi clicked start directly.

The moment Liu Chi clicked the start button, the robot seemed to be infused with a soul and came alive. The body, which had been standing still, raised its left foot and took a step forward with a "click".

"Wow...it's moving, Liu Chi, look." Ye Yuxin was jumping and screaming excitedly, as if she was seeing a sow climbing a tree for the first time.

Then two steps, three steps, four steps.

And the speed of raising legs became faster and faster, and after taking more than ten steps, it turned into a jog.

"Ahhhh!!! It's running again, so fast." Ye Yuxin followed the machine like an excited child.

Liu Chi smiled and followed. The entire flat ground was nearly 50 meters, which was finished in less than a minute. Then came the highlight of the test, a 120-degree turn plus a slope.

"We're going uphill, we're going uphill, we're going uphill..." Ye Yuxin didn't even dare to speak loudly. She clenched her fists tightly and stared at the robot that was quickly rushing towards the slope.

Keep going!

Liu Chi also stared at the tablet in his hand. At this time, the robot's speed was 1.5 meters per second, and it was getting closer and closer to the slope by 10 meters, 9 meters...

2 meters, 1 meter...

Going up the slope at this speed, I wonder if I will fall due to inertia.

Or just hit the edge?

arrive...

The robot seemed to have heard Ye Yuxin's 'call', and its body gently moved to the left, and with a 'whoosh', it rushed up the slope without slowing down.

"It passed, it passed. Liu Chi, did you see it? Did you see it? Our robot passed." Ye Yuxin hugged Liu Chi excitedly, shouting and jumping with excitement.

"Okay, okay, I get it. Yuxin, let go first. We are testing the robot." As soon as Ye Yuxin interfered, the robot disappeared from Liu Chi's sight and pushed Ye Yuxin out of reflex.

"Oh oh oh..." Ye Yuxin then realized how out of control she had been. Her face instantly turned red like an apple. She immediately let go of Liu Chi and secretly glanced at him guiltily.

In order to hide her heartbeat that was almost 200 times, Ye Yuxin hurriedly chased after the robot.

Liu Chi heaved a sigh of relief, shook his head, got rid of the 'wonderful' smell in his nose, and chased after Ye Yuxin.

The slope is about 15 meters.

By the time the two caught up with the robot, they were almost at the end of the slope.

"Come on!" Ye Yuxin clenched her fists, looked at the robot, and then looked at the winding gravel road in front of her, which was nearly 30 meters long.

At this time, the robot, like a warrior always moving forward, directly crossed the end of the slope, lifted its legs and stepped onto the gravel road.

"Bang, bang, bang..." Before Liu Chi could react, the robot rolled over and did three somersaults. In the last one, it lay on the ground with all four legs facing the ground, counting ants.

"Ah...the robot fell down." Ye Yuxin exclaimed and hurried forward to help the robot up.

"Yuxin, don't move." Liu Chi hurriedly grabbed Ye Yuxin's hand.

"But, but, but, but the robot fell down." Ye Yuxin struggled a little anxiously and spoke incoherently.

"Look at..." Liu Chi shook his head, gave Ye Yuxin a reassuring look, and then looked at the robot.

"Oh..." Ye Yuxin pouted.

The robot pushed itself up with its hands, straightened its waist, and stood up.

"Stand up..."

But after taking a few steps, the robot did a cat-and-mouse trick and fell to the ground again.

Liu Chi frowned. It seemed that this balance system still didn't work.

I have to change it when I get back.

An anti-suspension array can be added on each side, so that the anti-suspension can be used to maintain balance after the machine loses dry balance.

There is also a sensor system.

The ability to collect and analyze environmental information must also be strengthened, otherwise when encountering complex environments or emergencies, the reaction speed will not be able to keep up with the speed of progress.

Liu Chi looked at the robot's performance and recorded areas for improvement.

After stumbling and falling for five minutes, the robot finally managed to cross the 30-meter gravel road. The situation was not much better when it entered the bumpy dirt road.
