The robot's voice slowly entered Xiaoxin's ears. It wasn't a cold, mechanical voice, but rather like a voice actor, sometimes lively and sometimes powerful.

When it read "Action Kamen encounters a monster," its tone became much lower and it slowed down its speech. But when it read "Action Kamen transforms," ​​its voice suddenly rose, and its mechanical arm moved accordingly.

Shin-chan, who was standing nearby, stared wide-eyed and suddenly shouted excitedly, "Action Kamen! Charge! Fight the monster!"

The audience was amused by Shin-chan's actions, and some even took out their phones to record videos. Some whispered to the person next to them, "This design is so interesting, my child will definitely like it too."

Chairman Yamada smiled and said to those around him, "The fact that it can get children to interact shows that its voice and actions are designed to perfectly suit children's preferences. This is a true 'thoughtful little helper'!"

After the robot finished reading a chapter, Lin Yu smiled, patted Xiaoxin's head, and then stood up to address the audience: "As you all saw, the indoor robot's voice system can adjust its tone according to different stories, making it more immersive for children."

"In fact, we have made a lot of optimizations to enable the robot to understand what children say. It can recognize eight different children's voices, including the childish voice of three to five years old, the clear voice of five to eight years old, and even the unclear voice of children in the teething period. The recognition rate can reach more than 98%."

Lin Yu walked to the robot's side, gently touched its mechanical arm, and then said, "But more importantly, it's safe. We've controlled the maximum force of the mechanical arm to within 2N, which is equivalent to the force of picking up an apple. Even if a child accidentally touches the mechanical arm, they will only feel something soft and won't get hurt."

"Furthermore, the joints of the robotic arm are equipped with highly sensitive pressure sensors. As long as the force exceeds 2N, it will immediately stop moving to avoid squeezing, thereby ensuring the safety of children."

To demonstrate safety, Lin Yu conducted a small experiment. He placed a sponge on the robotic arm's trajectory and then had the robot retrieve a picture book. As soon as the robotic arm touched the sponge, it stopped instantly, and a message popped up on the touchscreen: "Obstacle detected, movement has stopped."

Seeing this, the audience nodded in agreement. President Sato's secretary whispered, "With such a safe design, we can feel very secure at home. We don't have to worry about the children accidentally bumping into things."

Around 10:20 a.m., the interactive session with the indoor robot ended, and the host returned to the stage, holding two blue-covered contracts: "Just now, we witnessed the practical functions and safety design of the indoor and outdoor robots, and I believe everyone has gained a deeper understanding of them."

The host smiled and continued, "Next up is the important signing ceremony of the press conference. We are honored to have invited two important partners who will become the first users of the robot in the market."

The host turned his attention to the audience: "First of all, please welcome President Sato of Tokyo Construction to the stage! Tokyo Construction is a well-known construction company in Japan with rich experience in construction site construction and building material transportation. Their choice to cooperate with our robots is a testament to their recognition of our product strength."

President Sato stood up from his seat, straightened his dark gray suit jacket, said to his assistant, "Prepare the contract," and then walked towards the stage.

As he walked steadily and with a firm gaze to the center of the stage, he first shook hands with Lin Yu. The handshake was of moderate strength, not too forceful, yet it conveyed his sincerity.

"Distinguished guests, good afternoon!" President Sato took the microphone from the host. "I am Sato from Tokyo Kenya. I am very honored to be able to cooperate with Lin Yu's robot team today. The efficiency of outdoor robots is dozens of times that of manual labor, and they have never malfunctioned, which makes us very reassured."

He paused and his tone became sincere: "Our construction site now relies on 10 workers every day to move building materials such as steel bars and cement blocks. Each worker carries 20 kilograms at a time, and they have to make 25 trips a day. Many workers have been doing this for several years and have developed back problems."

"Moreover, the monthly wages for 10 workers are 300 million yen, and we also have to bear the risk of workplace injuries. Now we have decided to order 20 outdoor robots first, with a monthly rental fee of only 25 yen. This will not only save on labor costs but also protect the safety of workers. This is a 'win-win' situation for us."

A round of enthusiastic applause erupted from the audience, and several guests from the construction industry nodded slightly, clearly agreeing with President Sato's statement.

President Sato smiled and looked at Lin Yu.

"Mr. Lin Yu, I hope that our cooperation will make construction site work more efficient and safer."

[Ding! Get to know Sato]

[Congratulations, host, you have obtained a white treasure chest]

[Ding! Sato's favorability has increased. Green treasure chest obtained.]

[Ding! Sato's favorability has increased. You have obtained a blue treasure chest.]

Chapter 280 A Successful Signing Ceremony

"Thank you for your trust, President Sato!" Lin Yu took the microphone. "We will make targeted adjustments to the robot based on the construction site scenario of Tokyo Construction, such as lowering the height of the robotic arm to a certain height to facilitate the handling of building materials, and we will also arrange for technicians to regularly go to the construction site for maintenance to ensure that the robot can work stably."

After speaking, the two picked up their pens and signed the contract. Lin Yu used a black ballpoint pen with the words "R&D Team" printed on the barrel, while President Sato used a silver pen he brought himself with the Tokyo Kengye logo engraved on the cap.

After signing, the assistant handed them red ink, and the two pressed their fingerprints on the contract, then exchanged contracts and bowed to each other. Flashbulbs went off incessantly as media reporters crowded around the stage to capture this important moment.

"Next, please welcome Ms. Tanaka from Matsumoto Electric to the stage!" the host said again. "Matsumoto Electric is a well-known Japanese home appliance chain brand with more than 100 stores nationwide. This time, they plan to place indoor robots in the children's area and home appliance experience area of ​​the stores to provide customers with more thoughtful services."

Ms. Tanaka stood up from her seat. She was wearing a beige suit, carrying a white folder in her hand. She walked with light steps and a gentle smile on her face.

"Hello Mr. Lin Yu, my name is Tanaka."

[Ding! Get to know Tanaka!]

[Congratulations, host, you have obtained a white treasure chest]

[Ding! Tanaka's favorability has increased. Green treasure chest obtained.]

[Ding! Tanaka's favorability has increased. You have obtained a blue treasure chest.]

When she walked onto the stage, she first nodded to Lin Yu and President Sato before taking the microphone: "Hello, everyone! I am Tanaka from Matsumoto Electric. I am very happy to cooperate with the Xiaoyu Robotics team. The reason we chose indoor robots is because of their 'interactivity' and 'practicality'. Nowadays, many parents bring their children to the store to buy home appliances, but the children get bored and cry and want to leave, so the parents can't look at the products with peace of mind."

She said with a smile, "We plan to place 2-3 indoor robots in each of our 20 stores in Tokyo and Osaka. Some of them will be placed in the children's area to read picture books with children and play games with them."

"Some are placed in the home appliance experience area to introduce how to use home appliances to parents. For example, if a customer wants to buy a washing machine, the robot can demonstrate the operation steps of the washing machine and recommend suitable models. This time we will order 50 units first, and we will increase the order quantity based on the feedback from the stores."

The atmosphere was exceptionally relaxed when Lin Yu and Ms. Tanaka signed the contract. Ms. Tanaka signed with elegance and then smiled and said to Lin Yu, "I hope the robot can become a 'little star' in the store and make more customers like Matsumoto Electric."

Applause erupted again from the audience. The host walked onto the stage, took the microphone, and said, "Thank you to Tokyo Kenya and Matsumoto Electric for your trust. This is not only our first order for indoor robots, but also an important step for us to enter the market. In the future, we will continue to optimize our products and provide practical robot solutions for more industries."

At this moment, Chairman Yamada suddenly stood up from his seat, and the audience immediately fell silent, with everyone's eyes focused on him.

He slowly walked onto the stage, took the microphone, and said in a solemn yet gratified tone: "As the president of the Japan Robot Association, I am very happy to see such a practical robot born today, and even happier to see it recognized by enterprises."

"The advantage of indoor and outdoor robots lies in 'not pursuing fancy functions, but only solving practical problems.' If the mining area needs a strongman, it will become a 'strongman'; if the family needs a caring assistant, it will become a 'caring assistant.' This is the original intention of robot research and development."

He looked at Lin Yu with anticipation in his eyes: "I have already communicated with several mining companies in Kansai. They are very interested in outdoor robots. After the meeting, we will arrange for them to connect with you. In addition, at the 'Japan Robotics Industry Conference' to be held in Osaka next month, we will arrange a separate exhibition area for indoor and outdoor robots. We hope you can bring your robot to the exhibition so that more people can see its advantages."

Lin Yu took the microphone and said with a smile, "Thank you for Chairman Yamada's recognition and support! We will definitely prepare well for the industry conference and present the practical functions of indoor and outdoor robots more comprehensively. We also hope to cooperate with more companies and use robots to solve more practical problems."

After the signing ceremony, the media Q&A session began. The host walked to the center of the stage and said with a smile, "The next 15 minutes are for media Q&A. If any reporters have any questions about Xiaoyu Robot, please raise your hands and Mr. Lin Yu will answer them one by one."

As soon as he finished speaking, a reporter in a blue shirt immediately raised his hand. His microphone had a "Tech Weekly" logo on it: "Hello Mr. Lin Yu, I am a reporter from Tech Weekly. May I ask how the after-sales service system for indoor and outdoor robots is established? For example, if the robot malfunctions, how should the user contact for repair? What items are included in the one-year free repair service?"

Lin Yu took the microphone and answered clearly: "Thank you for your question. We have after-sales service centers in Tokyo and Osaka respectively. The Tokyo after-sales service center is in Shinagawa Ward, and the Osaka one is in Tennoji Ward. If users encounter any problems, they can call our 24-hour after-sales service hotline, and our customer service will respond within 1 hour."

He paused, then continued, "The one-year free repair includes the replacement and repair of all parts, whether it's a damaged robotic arm for the outdoor robot, an aging battery, or a malfunctioning voice system or a faulty touchscreen for the indoor robot, all of which are covered free of charge."

"Moreover, during the maintenance period, we will provide a backup robot so as not to affect the normal use of the user. For example, at the Tokyo Construction site, if a robot needs maintenance, we will send a backup robot to the site within 24 hours to ensure that the construction is not affected."

"In addition, we have a spare parts warehouse with more than 500 kinds of robot spare parts, including common parts such as heat sinks, sensors, and batteries. We have ample stock, and if users need to replace parts, we can ship them on the same day, and even remote areas can be delivered the next day..."

The reporter from Techweek nodded and then asked another question: "So, what is the approximate lifespan of the robot? Will the repair costs be very high after the warranty expires?"

"The design lifespan of outdoor robots is about 10 years, and that of indoor robots is about 12 years," Lin Yu replied. "After the warranty period, we will provide 'lifetime maintenance' service. Repair fees will be charged at cost price. For example, if the cost price for replacing a battery is 2 yen, we will charge 2 yen and not make a profit..."

The Q&A session lasted 20 minutes, during which Lin Yu answered eight questions, covering topics from technology and the market to after-sales service and future plans. Each answer was candid and detailed, with no questions evaded. Reporters in the audience took notes, and some even took out recording devices, afraid of missing any important information.

Around noon, the host returned to the stage with a microphone and said with a smile, "Distinguished guests and media friends, the Xiaoyu Intelligent Robot launch event has come to a successful conclusion! Thank you all for coming. The exhibition area will be open for one hour. You are welcome to visit the robot up close. If you have any questions, you can consult the staff on site. In addition, we have prepared Japanese bento boxes in the lounge next to the exhibition hall for you to enjoy."

The background music changed to a more upbeat tune, and the guests got up and headed towards the exhibition area.

The warm lights in the exhibition hall were still on. President Sato's fingers gently traced the mechanical arm of the outdoor robot. The cool metallic touch made him turn around and sigh to Lin Yu, "If we had encountered this robot six months earlier, our construction site could have saved at least three workers with lumbar muscle strain."

Lin Yu smiled and handed over a cup of warm Gyokuro tea: "President Sato, rest assured, we will send technicians to the construction site for inspection every week. The lubricating oil of the robotic arm and the wear of the tracks will be recorded in real time. We can respond to any problems within 24 hours."

Not far away, Ms. Tanaka from Matsumoto Electric was having an indoor robot demonstrate how to operate the washing machine. The robot explained the water temperature control of the "wool wash mode" in a soft, gentle voice.

Several representatives from home appliance chains nearby were recording with their phones and nodding in approval from time to time. Ms. Tanaka caught sight of Lin Yu and waved with a smile: "Mr. Lin Yu, the representative from Kyoto Electric just asked if we could order 10 indoor robots to put in the children's play area. I've already given them Blackie's contact information."

"Thank you for the recommendation, Ms. Tanaka." Lin Yu had just walked over when he heard a series of crisp footsteps. It was Ms. Yoshinaga with Shin-chan and Kazama.

Shin-chan is standing on tiptoe, tugging at the robotic arm of the indoor robot, and saying, "Robot brother, spin around again!"

Mr. Yoshinaga quickly pulled him back: "Shin-chan, don't cause trouble!" Lin Yu smiled and waved his hand, saying to the robot: "Perform a Kamen Rider pose."

The robot's touchscreen flashed, and its robotic arm slowly rose, assuming a fist-like posture. This made Shin-chan jump up with cheers, and he couldn't help but lean over and whisper, "Can you let it calculate what 15 plus 23 equals?"

After the children had finished playing, Misae arrived carrying a bag full of snacks: "Shin-chan, have you had enough fun today? It's time to go home."

As the Batmobile smoothly drove through the streets of Tokyo at dusk, Lin Yu couldn't help but smile as he looked at the email sent by Blackie on his phone. The Tokyo Daily's technology section headline read, "Practical Robots Lead New Directions in the Industry."

Along with the photos he was showing off the outdoor robots, three overseas companies sent emails expressing their desire to visit Kasukabe next week, one of which was a German construction equipment giant specializing in mining machinery.

When they returned to the Nohara family home, Tsubaki was sitting on the sofa in the living room knitting gloves. The light gray yarn flew between her fingers, and next to her was the mohair that Lin Yu had brought back from the yarn shop last time.

"You're back?" Xiaochun looked up and smiled. "I just got a call from Nanako. She said she wants to come see you tomorrow and bring you a new sample copy of 'Akame ga Kill!'"

Lin Yu smiled, walked over and sat down next to her, touching the ball of yarn: "Did you knit this for me?"

Xiao Chun nodded, her ears turning red. "Winter is coming soon. This mohair is very soft and will keep you warm." Just as Lin Yu was about to speak, his phone vibrated in his pocket. It was a call from Hei Ji.

“Mr. Lin Yu, the second batch of White Snake Wine has sold out in pharmacies in Osaka. Several hot spring hotels also want to cooperate to turn White Snake Wine into a ‘hot spring specialty drink.’ Do you want to discuss it?” Heiji’s voice was full of excitement.

"A hot spring hotel?" Lin Yu's eyes lit up. "We can discuss it, but we need to emphasize the health benefits of the white snake wine, such as dispelling cold and warming the body. It will be even more effective when paired with hot springs. Also, have them send over the cooperation proposal. I'll reply after Nana and I have reviewed the sample copy tomorrow."

After hanging up the phone, Shin-chan ran over holding an Action Kamen plushie: "Yu, if Nana-chan comes tomorrow, can she play 'Robot Fighting Monsters' with me?"

Lin Yu ruffled his hair: "We'll have to ask Nana-chan if she's willing." Shin-chan immediately ran to the phone, standing on tiptoe to call Nana-chan, but Misae quickly stopped him: "It's so late, don't disturb Miss Nana-chan's rest!"

The next day, as soon as Lin Yu arrived at the kindergarten, Takakura Bunta greeted him warmly, "Lin Yu! I heard about your press conference yesterday, it was absolutely amazing!"

Takakura Bunta talked to Lin Yu about indoor robots for a long time, but he kept mentioning that he wanted to buy one. After chatting with him for a while, Lin Yu couldn't help but smile.

However, Lin Yu did not expose Takakura Bunta's words, but said, "I think our kindergarten can also use an indoor robot. This would not only take better care of the children, but also reduce the workload of the teachers."

Lin Yu looked at Takakura Bunta, paused, and then said, "How about I send one to the kindergarten?"

"This...this is too much!" Takakura Bunta quickly waved his hand at Lin Yu, who immediately replied, "It's alright, Director, this is just a token of my appreciation for the children!"

After hearing what Lin Yu said, Takakura Bunta felt embarrassed to refuse and could only keep thanking Lin Yu.

[Ding! Takakura Bunta's favorability has increased. You have obtained a purple treasure chest.]

Hearing the system message, Lin Yu raised an eyebrow, thinking to himself, 'So, Takakura Bunta's favorability improvement is still related to the kids!'

When Lin Yu returned home from get off work and entered the living room, he saw Ohara Nanako. She was wearing a beige knitted sweater and holding a light brown envelope containing a new sample copy of "Akame ga Kill!".

"The editor said the color pages for this chapter are especially beautiful, the scenes of Tatsumi and Akame infiltrating the Imperial Treasury are particularly vibrant in color." Nanako handed the sample copy to Lin Yu, her eyes sparkling.

Lin Yu flipped through the sample magazine's color pages. Tatsumi was dressed in black night clothes, his crimson eyes and sword gleaming coldly. The treasure vault in the background was filled with gold and silver jewels, yet it exuded a sinister aura.

"This is absolutely gorgeous!" Lin Yu said with a smile. "By the way, yesterday Hei Ji said a hot spring hotel wanted to collaborate on the White Snake Wine proposal. Could you take a look at it for me?"
