Multi-functional transfer robot apparatus

A multi-functional robot apparatus comprising:

• an upper plate formed by connecting one or more divided upper plates in a longitudinal direction;
• a porous flexible sheet which is included in each divided upper plate of the upper plate and reciprocates in a lateral direction, each section of the porous flexible sheet spaced apart from each other section in the longitudinal direction by a portion of one of the one or more divided upper plates, wherein the porous flexible sheet reciprocates in a lateral direction, on an upper surface of one of the one or more divided upper plates, both in a first direction from one side of the one or more divided upper plates to an opposite side of the one or more divided upper plates and in a second direction opposite to the first direction;
• a first roller that wraps and rotates one end of the porous flexible sheet to allow the porous flexible sheet to move in the first direction;
• a second roller that wraps and rotates the other end of the porous flexible sheet to allow the porous flexible sheet to move in the second direction;
• a pivot mechanism included between the divided upper plates such that each divided upper plate independently pivots vertically;
• and
• at least one hydraulic cylinder configured to adjust a height, a lateral tilt, and a longitudinal tilt of at least one of the divided upper plates.
