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 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.

The correct English name should be "wooden galloper with a free-standing cargo box" since said device walks in a gallop form. It was equipped with two handles to make it walk by manpower. The swing cargo box is used to store useless work caused by the up-and-down motion of the walking machine. When the cargo box swung forward, the walking machine steps forward at the same time to raise efficiency. This invention was specifically mentioned in the Romance of Three Kingdoms, Records of Three Kingdoms, Book of Qi, and some other works from the Song Dynasty.
