A father and son team have created replicas of the Transformers robots out of scrap metal using instructions downloaded from the internet . Peasant farmer Yu Zhilin and his son Yu Lingyun use pieces of scrap metal they have collected from disused cars in Hengyang in China to construct huge robots , similar to the characters of Optimus Prime and Bumblebee who appeared in the multi-million pound films . They have just sold an army of the metal robots for almost one million RMB ( £110,0000 ) constructed in their own makeshift workshop . Xhilin decided to start building the huge models in 2007 when he realised how valuable they could be in China - where the latest Transformers instalment , Age of Extinction , was the highest grossing film ever in the country . The film targeted Chinese audiences , with Chinese car brands featured throughout and Hong Kong used as the backdrop for some of the action sequences . The pair join a cult of Chinese people who have started making replicas of the metal robots that have earned such notoriety in the country . Last year a team of farmers in Xiaoye , a village in the eastern Shandong province , began making the models at a cost of around $ 16,000 ( £11,000 ) and selling them to property developers who have installed them in shopping malls in China . Yu Linguin has been helping his father Pu Zhilin ( right ) produce models of Transformers , using scrap metals from cars they have collected . Lingin is seen in the makeshift factory father and son have made , making a metal model by welding together disused car parts . The pair have been making the models since 2010 after realising the possible success due to the popularity of the films in China . The pair collect old disused car parts at their small Hengyang factory to construct the large models from the metal parts . Old wheels , discarded doors and rusting axles have all been used to piece together the impressive tower Transformers models . Zhilin and his son have worked together to produce the models and are shown here making an Optimus Prime replica Transformer . The pair made their scale Transformers models based on the success of the films featuring Optimus Prime ( left ) and Bumblebee ( right )
