A mobile robot includes an electric device unit disposed inside a cover and upward of a robot, and a transport mechanism disposed downward of the robot. An end part of a rotation shaft of a motor driving an arm portion of the robot faces downward. The cover includes a partition plate separating a first housing space in which the electric device unit is housed and a second housing space in which the robot is housed. The partition plate has a protrusion protruding into the first housing space. The protrusion provides a motor housing space in the second housing space. At least one part of the first motor is housed in the motor housing space when a base of the robot is elevated to an uppermost position.

A power transmission unit of a wireless power feeding device supplies power to two or more moving bodies wirelessly by using magnetic field resonance. The power transmission unit includes a power transmission coil, a high frequency generation unit, capacitor circuit groups, and a control unit. The capacitor circuit groups have series capacitors connected in series with the power transmission coil and parallel capacitors connected in parallel to the switching elements for generating a high frequency, and the capacitor circuit groups are set together with the power transmission coil so as to have different impedances to each other. The control unit that controls a switch for connecting and disconnecting the capacitor circuit groups according to the number of the moving bodies to which electrical power is supplied from the power transmission coil.

Power transmission unit of wireless power feeding device

In a wireless power supply apparatus, a first unit electrically connected to a power supply and a second unit electrically connected to an electric load. Power transmission is performed wirelessly between the first and second units using a magnetic resonance phenomenon. Each of the units has a resonant amplifier circuit provided with switching means driven by a drive signal, a resonant coil to which a high-frequency signal generated by the resonant amplifier circuit is supplied such that the resonant coil functions as a resonant inductor on the resonant amplifier circuit, and electric storage means electrically connected to the resonant amplifier circuit so as to be capable of charging and discharging power. The second unit includes current detecting means for detecting a current flowing through the storage means, and phase control means for controlling a phase of the drive signal for the switching means based on the detected current.

Wireless power supply apparatus

A wireless power supply apparatus includes a power reception coil, an actual load and an auxiliary load. The power reception coil functions as a repeater for receiving electric power in a non-contact manner by magnetic resonance with a power transmission coil to which electric power is supplied from a power supply unit and relaying transfer of the electric power from the power transmission coil. The actual load is connected to the power reception coil and is powered by the electric power received by the power reception coil. The auxiliary load is inserted parallel to the power reception coil and the actual load and forms a closed circuit with the power reception coil when supply of the electric power to the actual load is interrupted to be in an open state.

Wireless power supply apparatus, filter unit and power supply apparatus for robot using the filter unit

A wireless power supply apparatus using magnetic resonance is provided for a linear motion type robot. In the apparatus, a high-frequency signal for foreign matter detection is generated. This signal is different in wavelength and frequency from a high-frequency signal for transmitting power between a power transmission coil and a power reception coil. The wavelength is wavelength &#x3bb; and the frequency is frequency f. The power transmission coil serves as an apparent antenna of which the long side is set to &#x3bb;/2. At least either of a wavelength &#x3bb;x or a resonance frequency fx of a resonance wave attributed to the resonance in the antenna is detected when the high-frequency signal is supplied to the antenna. Whether or not foreign matter is present on the power transmission coil is detected based on the wavelength &#x3bb;x or the resonance frequency fx.

Wireless power supply apparatus for linear motion type robot

A direct drive type system such as a direct drive type robot is provided. This system includes a rail member, a movable member guided by the rail member and movable along the rail member, and an electric motor to drive the movable member. The system includes a transmission coil and a reception coil. The transmission coil has plural transmission coil segments which are planar coils and arranged on and along the rail member. High-frequency power is supplied to the transmission coil from a power source. The reception coil is arranged on the movable member to be opposed to the transmission coil and configured to an area faced with each of the transmission coil segments, wherein the area is smaller than that of each transmission coil segment. The reception coil receives power from the transmission coil without contact by a magnetic resonance. The received power is supplied to the motor.

In one of a pair of supporting pillars, a clearance is formed in a side of a moving space of a side of a main robot body. Then, when the main robot body stops in the position immediately near the supporting pillar and an arm is turned, the range in which the arm can turn is expanded without contacting the supporting pillar.

Suspending robot system

A plurality of cables is unified into a parallel in a vertical direction state to constitute a flat cable, and the flat cable is pressed against an internal surface of a perimeter of the Cableveyor. Further, both ends of the flat cable are fixed such that the flat cable touches neither upper or lower inner surface of the Cableveyor by slanting up both ends of the accommodated portion of the flat cable.

Suspended robot system

Since the rotating unit is disposed so that the drive part, which constitutes the rotating unit, is located in the inner side of the bent portion with the curved surface of the CABLEVEYOR in the side of the straight axis, there is no problem occurs by locating the drive part connected with the rotating unit in the inner side of the bent portion of the CABLEVEYOR. Therefore, the dead space formed in the inner side of the bent portion of the CABLEVEYOR can be used effectively.

Industrial robot having a suspended unit

The Cableveyor may be able to support its own weight in the direction of gravity since the Cableveyor having the bent portion that connects between the straight-moving unit and the rotating unit is arranged so that it bends in a horizontal plane. As a result, the Cableveyor and the maintenance member do not collide, thus collision noise or dust caused by the collision can be suppressed. Moreover, since the Cableveyor is arranged to the side of the straight axis, the height size of the robot can be suppressed compared with the composition that arranges the Cableveyor on the upper surface of the straight axis.
