Abstract
A self-propelled apparatus includes a main body and an anti-drop system. The main body includes an aperture located at a bottom portion thereof and communicative with an interior thereof. The anti-drop system located inside the main body respective to the aperture includes an infrared detection module and an angle-limiting unit electrically coupled with the infrared detection module. The infrared detection module detects a distance between the bottom portion and a first detection surface. The infrared detection module includes an infrared emitting unit and an infrared receiving unit. The infrared emitting unit emits an infrared signal to the first detection surface. The infrared signal produces a first boundary signal and a second boundary signal after the infrared signal passes through the angle-limiting unit. The infrared receiving unit receives a reflected signal of the first boundary signal with respect to the first detection surface.
