Abstract: A robot includes a trunk portion frame (functioning as a “base portion”), a head portion frame (functioning as a “first movable portion”) supported by the trunk portion frame, a flexible outer skin provided in such a way as to come into contact with the head portion frame and cover the trunk portion frame, and a pair of arm portions (functioning as a “second movable portion”), provided in contact with the outer skin, whose relative displacement with respect to the trunk portion frame changes in accompaniment to a displacement of the outer skin that accords with an operation of the head portion frame.

Abstract: Ease of connecting to a robot in a charging station is increased. A charging station includes a base having an upper face up on which a wheel rides, and a power supply terminal to be connected to a charging terminal of a robot. The upper face of the base is such that a target position is set in a far side region, while a reference entrance line that connects an entrance side specific position and the target position is set, and the upper face of the base includes an inverted face of a three-dimensional curved form that provides an entering wheel with a gravitational component that acts toward the reference entrance line side. The power supply terminal is connected to the charging terminal in a state wherein the wheel has arrived at the target position.

Abstract: A sensor is provided with a sensing unit for generating electrical signals responding to a physical quantity, multiple terminals for an electrical connection with an external, multiple signal wires for transmitting the electrical signals to the terminals, a connector housing where the terminals are accommodated, and an electrically isolating case, to which the terminals are fixed. The terminals and the electrically isolating case are inserted into the connecter housing. Thus, the connecter housing can be singly formed without being insert-molded. Accordingly, the manufacture performance of the sensor can be improved.
