Within a moving robot of narrow footprint, having quick traveling performance on a plane-surface, as well as, anti-tumbling function, and further being suitable for operations under coexistence with a human being, being able to travel coping with traveling situations on a level difference, etc.: in front and rear of main driving wheels 2 and 3, each being controlled through the inverted pendulum control, are disposed supporting legs 4 and 5, tips of which can be lifted up and down, wherein the tips of the supporting legs 4 and 5 are positioned to keep a predetermined distance between a traveling surface, when running on the inverted two-wheels travel, and the supporting legs 4 and 5 are fixed or either one in the fall-down direction is thrust out into the fall-down direction, so as to protect it from falling down. Further, upon the basis of detection information of floor-surface distance sensors 4e and 5e and side-surface distance sensor 4f, 4g, 5f and 5g, which are provided at the tips of the supporting legs 4 and 5, the robot senses an existence of a level difference and/or an inclined surface, so as to let the supporting legs to escape from the level difference and/or the inclined surface, and holds the position of gravity center thereof, stably, through other one of the supporting legs, being landed on the ground, and the main driving wheels 2 and 3; thereby enabling to travel over the level difference and the inclines surface.
摘要:
Autonomous mobile equipment includes a position-of-object and own position detecting system and a moving unit, and autonomously moves. The position-of-object and own position detecting system includes a database in which pieces of information on the superficial shape and position of an object are recorded. The superficial shape of the object detected by a position measuring unit is collated with the superficial shape of the object recorded in the database. If the collated superficial shapes agree with each other, the pieces of information on the object recorded in the database are transmitted to a traveling planning unit. If the collated superficial shapes disagree with each other, the information on the object acquired by the position measuring unit is transmitted to the traveling planning unit.
