Abstract

This robot hand comprises: a plurality of finger modules; and a connection part that rotatably connects two adjacent finger modules among the plurality of finger modules. Each of the plurality of finger modules includes: a finger including a plurality of joints; a finger motor including a finger motor shaft that operates the finger; a placement motor installed parallel to the finger motor and including a placement motor shaft; a housing installed below the finger and formed to accommodate the finger motor and the placement motor; and a placement gear installed on the upper surface of the housing so as to be concentric with the centerline of the placement motor shaft, wherein the two placement gears of two of the finger modules that are adjacent connected by the connection part are engaged with each other, and when the placement motor is operated, the finger module corresponding to the operated placement motor rotates about the placement motor shaft.
