DRUG DELIVERY ROBOT

A drug delivery robot is provided. The drug delivery robot comprises: a storage space in which a drug is stored; a first accommodation unit formed at the front of the storage space along a first direction; an outlet by which the first accommodation unit communicates with the outside; a body having a first communication hole by which the storage space communicates with the first accommodation unit; a front rotational magnet which is located in the first accommodation unit and has a central axis arranged in a second direction perpendicular to the first direction; a first fixed magnet which is fixedly coupled to one side of the body in the rear of the front rotational magnet; and a second fixed magnet which is fixedly coupled to the other side of the body while having the storage space between the first fixed magnet and the second magnet and is arranged to face polarities different from those of the first fixed magnet, wherein the front rotational magnet can selectively rotate around an axis of the first direction or the second direction by means of an external magnetic field control, the body rotates together around the axis of the first direction when the front rotational magnet rotates around the axis of the first direction, the front rotational magnet opens or closes the first communication hole by means of the magnetic force with the first fixed magnet and the second fixed magnet when the front rotational magnet rotates around the axis of the second direction.
