Robot for conveyance

A conveyance robot is provided to withdraw and supply a product to be returned simultaneously by forming a plurality of robot arms capable of being controlled independently, thereby reducing work time and improving productivity. A conveyance robot comprises a base(20), at least one column(40), at least two robot arms(50), a slider(51), and at least two linear moving units. At least one column is rotatably installed at the base. At least two robot arms are installed at the column. The robot arms are linearly moved along the column to withdraw and supply a product to be returned. The slider is formed at the robot arms and is linearly moved moving along the column. At least two linear moving units are installed between the column and the robot arm to allow the robot arm to be rectilinearly moved. At least two robot arms are independently and are linearly moved on at least on column through the linear moving units, thereby a plurality of robot arms working synchronously. The linear moving unit has a rack, a pinion, and a motor. The pinion is tooth-engaged with the rack. The motor is connected with the pinion.
