Wooden Ox

The wooden ox (木牛流馬，lit. wooden ox flowing horse) was created by Zhuge Liang while he served Shu-Han. It was a thought to be either

• a mechanical, walking replica of an ox whose main purpose was to carry supplies such as grain to an army that was running low on supplies

or

• a sort of wheelbarrow that had 2 booms on which it was pulled (this was later reversed with the "gliding horse").
