photoresistors(LDR) va infrared (38kHZ) mamoolan behtarin optionha hastan baraye robots.

albatehnemishe goft injoori mesle in axa mibineh,

to LDR mamoolan ye dual comparator mizaran bad 2 ya 4 ta LDR ha ba taghir e light Voltage difference shoon avaz mishe, comparator am ino pick up mikoneh be transistor e ke mamoolan be motor vasl hast (mamoolan PNP) ye low voltage signal mifresteh, transistor am chon PNP e (hamishe is set to 1) motor o az kar mindazeh.

infrared mamoolan bara wall avoid robots bekar mireh, tori ke ba ye inverter ya timer e 555 chip signal generate mikonan (mamooan 38Khz , mesle remote e TV ) ba infrared emitter , pakhesh mikonan ye detector am dareh ke vaghty in signal bar migardeh mifahme jolosh chi kojast.
