Provided is a robot cell apparatus in which a cooperatively operable area for a pair of robot arms can be widened and which has an excellent workability. The present invention includes a table with a plane having a quadrangular shape in plan view, a workpiece being placed on the plane. Proximal ends of robot arms are respectively fixed to two corners at diagonal positions among four corners of the plane of the table. A cooperatively operable area in which the pair of robot arms are cooperatively operable is formed in a space above the plane of the table.

Robot cell apparatus and production system

To enable positioning a robot arm and a workpiece with high accuracy while reducing vibrations of a camera. According to the claimed invention for this purpose, a robot stationincludes a pedestalto which robot armsandare fixed, a camerawhich images an area including a working areaof the pedestal, and a boothto which the camerais fixed. The pedestalis fixed to a floor surface, and the boothis fixed to the floor surface without contacting the pedestal. The boothis formed in the shape of a rectangular parallelepiped having a short side parallel to a workpiece conveying direction T and a long side perpendicular to the workpiece conveying direction T in a plan view. In the booth, the length of the long side y of the boothis set to not less than the sum of a maximum length by which the robot armsandprotrude from the pedestalin a direction perpendicular to the workpiece conveying direction T and the length in the direction perpendicular to the workpiece conveying direction T of the pedestalin a plan view.

Assembling apparatus and production system

In a gripping device, a displacement-type force sensor is provided on a side of a driving mechanism opposite fingers to which the driving mechanism is connected to form a grip section. The driving mechanism is supported on a housing with an elastic member being disposed therebetween at a position closer to the fingers than the center of gravity of the grip section.

Gripping device and system including the same

A cylindrical piezoelectric element is arranged to share an axis with a cylindrical vibrator having different diameters at central and end portions to fix the vibrator forming a gap at the central portion. Vibration voltages are applied across first electrodes on the piezoelectric element and the vibrator, namely, a second electrode, to vibrate the vibrator and bring a wave front of a traveling wave into contact with a tubular member, i.e., a supporting member fitted to the vibrator. Friction at a contact portion of the vibrator moves a mover including the vibrator and the piezoelectric element in an axial direction of the tubular member. By amplifying the vibration amplitude using the vibrator provided separately from the piezoelectric element, a small actuator capable of performing high-speed driving is realized.
