An 85 years old primary school building in Shanghai (China) has changed its location from its former to a new location using a technology dubbed the “walking machine.”
Resident living in Huangpu district who are very familiar to the school building were amazed as they recognised the new location of the school.
According to the engineering responsible for the walking machine, nearly 200 mobile supports were put under the story building to help move it to new location.
The supports act like robotic legs. They’re split into two groups which alternately rise up and down, imitating the human stride.
Attached sensors help control how the building moves forward, said Lan, whose company Shanghai Evolution Shift developed the new technology in 2018.

According to a statement from the Huangpu district government, the Lagena Primary School was constructed in 1935 by the municipal board of Shanghai’s former French Concession.
It was moved in order to make space for a new commercial and office complex, which will be completed by 2023.
Workers had to first dig around the building to install the 198 mobile supports in the spaces underneath, Lan explained.
After the pillars of the building were truncated, the robotic “legs” were then extended upward, lifting the building before moving forward.
Over the course of 18 days, the building was rotated 21 degrees and moved 62 meters (203 feet) away to its new location.
The relocation was completed on October 15, with the old school building set to become a centre for heritage protection and cultural education.
The project marks the first time this “walking machine” method has been used in Shanghai to relocate a historical building, the government statement said.
The city also has a track record of relocating old buildings. In 2003, the Shanghai Concert Hall, built-in 1930, was moved over 66 metes (217 feet) to make way for an elevated highway.
The Zhengguanghe Building a six-story warehouse, also from the 1930s — was then shifted 125 feet (38 meters) as part of a local redevelopment in 2013.
More recently, in 2018, the city relocated a 90-year-old building in Hongkou district, in what was then considered to be Shanghai’s most complex relocation project to date, according to state-run news agency Xinhua.
