Self-propelled cleaner and self-propelled traveling apparatus
First Claim
1. A self-propelled cleaner including a body equipped with a cleaning mechanism, a drive mechanism to steer and drive said body, and an alarm to give predetermined alarm or information at a preset time, comprising:
- a plurality of human sensors to be disposed roughly equiangularly;
a camera with predetermined viewing angle; and
a sleep determination processor that, when one of said plurality of human sensors detects a human, turns said body in the direction in which said camera faces the direction of said human sensor, takes images of said human with said camera, and determines whether or not the human is sleeping, by determining if the human is lying down and/or whether or not the human is at rest, based on the imaging signals from said camera, wherein;
said alarm gives said predetermined alarm at said preset time, when said sleep determination processor has determined that the human is sleeping.

Abstract
Disclosed herein is a self-propelled traveling apparatus capable of precisely determining whether a human is sleeping or awake, thereby eliminating useless alarms. When a human is detected by one of four pyroelectric sensors, the body of the self-propelled traveling apparatus is turned so that a CCD camera faces the direction of a pyroelectric sensor that detected the human, and takes images of the human. Then, based on the imaging signal generated by the CCD camera, the movement and posture of the human is detected. When it is determined that the human is at rest and lying down, the human is considered sleeping and an alarm is sounded at a preset time.
