A father and son team have created stunning replicas of "Transformers" robots using just scrap metal and instructions they found on the internet.

Farmer Yu Zhilin and his son Yu Lingyun used scrap metal they collected from old cars in Hengyang, China to make the gigantic robots that look identical to "Transformers" stars Optimus Prime and Bumblebee, according to the Daily Mail.

The Optimus Prime and Bumblebee models, which are about 20-feet-tall each, recently sold for about $147,000.

Some rural workers in China are even giving up their jobs to make huge Autobot and Decpticon replicas for astonishing amounts.

The fourth film in the "Transformers" franchise "Transformers: Age of Extinction" was such a huge hit last year in China a group of 11 farmers in Xiaoye village decided to team together to build robots as tall as 52 feet from spare car parts, according to the China Daily newspaper.

A number of the robots took more than a month to make, and while they aren't actually functional Transformers, they are still pretty extraordinary.

Farmer Wang Shizun, one of the many people involved in the construction process of the Transformers, told China Daily just how hard it is to make the replicas.

"Once we have the structure, all the parts are welded and assembled by piece according to the blueprint," Shizun said.

 "Transformers: Age of Extinction" became the all-time highest-grossing movie ever in China, earning $279.75 million in just 10 days after its release.
