A mobile body positioning station and a mobile body positioning system include a first partition, a second partition disposed along a direction intersecting an extending direction of the first partition, and a guide device as a guide disposed on a movement path of a robot as a mobile body. The guide device is disposed along an oblique direction with respect to the direction perpendicular to the extending direction of the first partition to extend from the first partition toward the second partition side. The guide device is configured to make the robot move in the oblique direction more easily than move in directions other than the oblique direction, and the guide device moves the robot along the first partition toward the second partition.

Mobile body positioning station and mobile body positioning system

An explosion-proof apparatus includes a frame having a hollow shape; a gas supply device configured to maintain inside of the frame at pressure higher than certain pressure by supplying gas to the inside; an electrical component disposed inside the frame; a battery configured to supply power to the electrical component; a protective device configured to stop power supply from the battery to the electrical component; a battery housing enclosure being an increased-safety explosion-proof enclosure configured to house the battery therein; and a protective device housing enclosure being a flameproof explosion-proof enclosure configured to house the protective device. The battery does not include a management device that manages parameters of the battery.

Explosion-proof apparatus

A charging system includes: a movable body including a frame and a battery provided in the frame; and a charging station configured to charge the battery. The movable body includes: a pressure detection unit configured to detect pressure in the frame; and a charging permission signal output unit configured to output a charging permission signal indicating that the pressure in the frame is detected to be equal to or higher than a threshold pressure. The charging station includes: a charging permission signal acquisition unit configured to acquire the charging permission signal from the charging permission signal output unit; and a power transmission unit configured to execute non-contact charging of the battery when the charging permission signal is acquired by the charging permission signal acquisition unit.

Charging system, charging station, movable body, and charging method

An explosion-proof robot is an explosion-proof robot which is capable of self-propulsion on a field and includes: an explosion-proof casing of a hollow shape inside of which at least one electric component is placed; and a cover including a nonmetal material and covering at least part of an outer surface of the explosion-proof casing.

Explosion-proof robot

An explosion-proof device includes a frame having a hollow shape, the frame housing an electrical component and a battery capable of supplying the electrical component with electric power. A protection device is configured to stop electric supply to the electrical component from the battery, if there is a risk of an explosive atmosphere entering the frame. The battery is housed in an explosion-proof container, within the frame, and thus it is possible to suppress damage to surroundings effectively even in case of ignition of an explosive atmosphere flowing into the frame by the battery.
