Abstract: There is provided a self-propelled electronic device for use on a base surface. The electronic device includes a chassis disposable over the base surface. The chassis includes a first surface facing the base surface when the chassis is disposed thereover. A light meter is configured to detect light incident toward the first surface and determine a luminance level thereof the detected light. A light source is configured to transition between an ON and OFF states dependent on the luminance level of the detected light. A line sensor is coupled to the chassis and is configured to sense a line segment on the base surface. A movement mechanism is coupled to the chassis and is placeable on the base surface. The movement mechanism is in operative communication with the line sensor to move on the base surface in a pattern corresponding to the line sensed on the base surface.
