In fact, human exploration of machinery has never stopped, and mechanical dogs have existed for many years.

The BigDog from 2005 was a pioneer, measuring 0.91 meters long, 0.76 meters high, and weighing 110 kilograms. It was equipped with a laser gyroscope, stereo vision, and approximately 50 sensors.

Funded by the U.S. Defense Advanced Research Projects Agency (DARPA), the project aimed to create a robotic mule to accompany infantry on marches, but the U.S. military ultimately did not purchase it due to excessive noise and size.

Then, in 2010, the LS3 was considered the pinnacle of this type of mechanical mule. It had sufficient load-bearing capacity, could run 24 hours a day when fuel was plentiful, and could even reach a top speed of 45 kilometers per hour.

It already has the ability to follow designated personnel or autonomously reach its destination using GPS navigation.

However, the hydraulic power system is too noisy and has a high failure rate, making it difficult to repair in the field.

Italy also had a similar HyQ series during the same period. China's 863 Program also had many universities making similar prototypes, such as Shandong University's SCalf, Shanghai Jiao Tong University's Little Elephant, and Beijing Institute of Technology's 16-DOF hydraulic quadruped.

Furthermore, Shanghai Jiao Tong University showcased a six-legged octopus robot at the Shanghai Science and Technology Festival, which can be used for emergency disaster relief at nuclear power plants.

However, their design concepts are very outdated, primarily consisting of hydraulic robots. While they have strong load-bearing capacity, their enormous weight makes them extremely cumbersome and inflexible. Their applications are limited even in the military field, and no one has ever considered using them in the industrial sector.

Chen Yiran's Watcher D1 is closer to the image of the machine in various novels and movies: fully electric, silent, lightweight, and flexible.

With its full range of sensory capabilities and advanced chips for reasoning and decision-making, this robotic dog is unlike previous robots that could only be used to move goods. It is much more capable than others. In addition to measuring data, it can also perform tasks such as turning valves when different modules are installed.

This time, it can really be used for industrial inspection.

Less than half a day after the press conference ended, the two videos of drilling the pipe gallery and tightening the valve were all over the internet.

ABC and CNN dedicated special segments to seriously discussing the future impact of aurora robots. While the presenter wasn't very familiar with the industry, and although experts suggested waiting and seeing, the CNN presenter firmly believed this was the beginning of the future.

TechCrunch, The Verge, and other media outlets also urgently published columns describing the huge changes that are about to take place in the field of industrial inspection.

Online, the arguments were even fiercer.

Because Chen Yiran habitually conducts live-streamed press conferences, netizens didn't even wait for media comments and immediately launched a frenzy of discussion online.

What some people are most concerned about is when this thing will be affordable enough for every family to buy one. Especially for those who live alone, they don't want to keep dogs or cats because they think it's too much trouble, but being alone can be lonely sometimes. If they die at home alone one day, no one will know, and what if they decompose?

It would be great to have a robotic dog. If something happens, it could break down the door to call for help, or it could call the police to come and collect the body.

Many more people are concerned about the impact this will have on the stock market. They're preparing to follow Chen Yiran's lead and make a killing.

There's also a group of people who are having fun and are relentlessly mocking Google.

While Chen Yiran founded Aurora Mobile and was aggressively acquiring various mechanical technology companies, Google, in an effort to achieve parity, acquired Boston Dynamics, which was then the most well-known company online.

From a traffic perspective, this wasn't a bad deal. Boston Dynamics' various videos are indeed very eye-catching; the balance and running and jumping of the humanoid robots are impressive, which even helped stabilize Google's stock price.

But now, more than a year later, Aurora Group has begun to release products and is truly moving beyond videos and PowerPoint presentations.

However, there seems to be no news at all about Boston Dynamics from Google's side.

Moreover, the technical approach of the Watcher D1 is completely different from that of Boston Dynamics. In fact, as the pioneer of the industry, Boston Dynamics has indeed influenced the overall thinking of many later entrants. Most people who enter this industry assume that hydraulics is the best approach.

The Watcher D1 completely abandons Boston Dynamics' hydraulic approach and uses pure electric drive, which currently seems to be a much more practical choice than hydraulics.

This means that Boston Dynamics could potentially lose all of its previous leading technologies.

Many people started leaving comments on Boston Dynamics' YouTube channel, asking them to rate the Watchmen D1.

Of course, there are also quite a few people who are worried because of this press conference.

Most of them are just pessimistic leftists. They are worried that the Watchers will take away human jobs and that the Terminator storyline will eventually unfold, with Chen Yiran finally revealing his true nature as a mad scientist and ruling the earth with robots.

But there is also a small group of people who are truly disheartened.

Baker Hughes is a company that is difficult for ordinary people to access; they only do business with oil companies.

Their CEO, Martin Craighead, is a supporter of Chen Yiran. He has bought a lot of Apple shares and always thought that the robots Chen Yiran created should be like those in Terminator, which would come out and wreak havoc.

He never expected that the first thing to appear would be a mechanical dog.

He angrily told his secretary, "Quickly, contact TD Williamson, the Lawson Group, and NDT Global. We need to get moving and refute him immediately. What does it mean to liberate humanity from those dangerous jobs?"

"The pipeline inspection industry isn't a blank slate; there are people in this industry! The four of us have been doing this for years; you can't just ignore us like this!"
