A light spot indication robot and a light spot indication method thereof are arranged. The light spot indication robot comprises a robot body which is arranged with a control module, a camera module and a laser indication module (100), wherein the laser indication module (100) emits a laser beam, the imaging module shoots to-be-indicated objects to form an image plane, the laser beam and the to-be-indicated object are projected onto the image plane to form a laser spot projection position and to-be-indicated object projection positions, respectively. The light spot indication robot is also arranged with a signal input module. According to content shown on the image plane of the to-be-indicated objects shot by the imaging module and input information of the signal input module, a target object among the to-be-indicated objects is determined. The control module controls the laser indication module to move, so as to cause the laser spot projection position to coincide with a projection position of the target object in the image plane. The present invention converts the location in a three-dimensional space into the location in a two-dimensional space, and has a small computation amount and a quick and accurate position indication.
