Abstract
Systems and methods are presented for operating a self-propelled device. In examples, an indication of a surface color on which the self-propelled device operates is received from one or more optical sensors. A color transition from a first color to a second color may be determined based on the received indication. Based on the determined color transition, an activity may be determined. For example, an activity may cause the self-propelled device to move, emit a sound, or illuminate a light, such as an LED. The determined activity may then be performed. In some examples, a hysteresis band may limit the effects of noise and other variations in the color signal. Accordingly, a color transition may occur when color values associated with the surface color indicated are within a first area but not within a second area.
