Charging apparatus for use with a mobile robot

A charging apparatus used with a mobile robot (30) has an improved charging structure so that a mobile robot (30) is easily brought into electrical contact with a charging unit (10), thereby reducing manufacturing costs and preventing a charging failure. The charging unit (10) is provided with a plurality of charging terminals (20) which are brought into electrical contact with corresponding ones of contact terminals (33a/b) of the mobile robot (30). Each of the charging terminals (20) includes a body (21) and a head (21a). A contact plate (23) is mounted to a predetermined portion of the head (21a) to be brought into electrical contact with a corresponding one of the contact terminals (33a/b).
