Abstract: A robotic sunlight tracking apparatus reduces power consumption and improves efficiency of solar photovoltaic power generation. The apparatus includes a solar cell module for converting sunlight into electricity, a rotation shaft connected to a backside of the solar cell module for supporting the solar cell module while rotating, a cylindrical body under the rotation shaft having a cam with a curvature formed as a recess in a surface of the cylindrical body and a motor built therein to rotate in one direction by operation of a timer, and fixing means for fixing the cylindrical body to ground. The rotation shaft includes a cam follower at one side of the cylindrical body placed in the cam for moving following the cam as the motor rotates, and a lift arm connected to the cam follower for moving up/down, adjusting an angle of the solar cell module when the cam follower moves.
