It reacts quickly,obeys commands and doesn't leave unpleasant surprises on the floor.This is the AlphaDog.The high-tech dog uses sensors and Artificial Intelligence(AI)technology to learn about its environment,and can even be taken for walks.“It's really very similar to a real dog,” says Ma Jie,chief technology officer at Weilan,the company behind the product.

The robot dog,which moves at a speed of almost 15 kilometres per hour,is the fastest on the market.With four metal legs,it is more stable than a real dog.The robot can predict the friction（摩擦力）and height of the ground to adjust itself and adapt to the environment.The creators are using 5G technology,super-fast Internet speeds with immediate reaction times,to make the robot operate autonomously.

As China seeks to upskill its workforce,the country has been making huge investments in robotics and AI.Robots are already used to deliver parcels,serve in restaurants,offer information at stations and even take throat swabs for COVID-19 tests.In the first month of sales,more than 1,800 AlphaDogs have been sold out,despite the high price of 16,000 yuan.Orders are mostly from computer developers,tech geeks （科技迷）,and also kids,who really seem to like it.

The Weilan workshop is staffed by young tech enthusiasts,filled with pencil design sketches and a central obstacle route of stairs and slopes for the machines to move on in testing.Developers there hope future uses of their four-legged friend could be conducive to the visually impaired.“To help the disabled is an important developing direction for us,” says Ma.“When the robot dog has the function of vision,hearing and dialogue,it can easily interact with disabled people,and lead them to the supermarket or the bus.”

Future software updates will include the dog “barking”—and beyond that,even add human voices to allow conversations between pet and owner.There is also a larger enterprise dog model,designed for industrial inspections of machinery or pipes.The next generation of the AlphaDog in pet form could also introduce personalities to make them look like dogs more,as well as extend its somewhat brief battery life.
