A robot apparatus includes: a robotic arm provided with a robotic hand capable of changing its position and its orientation by using joints; a visual sensor which measures a position or an orientation of a gripped object gripped with the robotic hand at a measurement teaching point; and a control device. The control device controls the position or the orientation of the gripped object when the gripped object is attached to an attachment target object at a corrected teaching point corrected based on a measurement result by the visual sensor. In this case, the control device determines a measurement teaching point, where the measurement with the visual sensor takes place, such that a driving direction of each of the joints from the measurement teaching point to the corrected teaching point is set to a definite driving direction.

A controller corresponding to production equipment, requiring upgrade can be selected automatically, thereby reduction in operating rate can be reduced. When software is upgraded, version upgrade software relating to a predetermined action description and version information are transferred to a controller management apparatus (S). A version change determination unit selects a controller including the predetermined action description described in the version information (Sand S). The selected controller downloads the new version of software to change the software (Sand S) after stopping operation of the production equipment. On the other hand, a controller not selected does not download the software, and the operation of the production equipment is not stopped.

A robot apparatus includes a manipulator, a teaching apparatus, and a control apparatus. The manipulator includes a hand and an arm having a plurality of joints. The teaching apparatus teaches operation of the manipulator. The control apparatus controls the manipulator based on a control signal from the teaching apparatus for causing the manipulator to operate in a predetermined operation direction. In a case where the predetermined operation direction has been checked, the control apparatus transmits, to the manipulator, a control signal for causing the manipulator to operate at a regular speed. In a case where the predetermined operation direction has not been checked, the control apparatus transmits, to the manipulator, a control signal for causing the manipulator to operate at a speed lower than or equal to a safety speed that is set based on the regular speed.

A wave plate capable of increasing a birefringence quantity and being made into a thin film, and a method of manufacturing the wave plate. The wave plate includes a substrate, whereon convex portions and concave portions are formed with a period less than or equal to the wavelength of light that is used therewith, columnar portions, wherein fine grains of a dielectric material are layered by oblique vapor deposition of a dielectric material from two directions, in a columnar shape on the convex portions in the vertical direction relative to the surface of the substrate, and interstices that are located on the concave portions and disposed between the columnar portions. Using birefringence from the fine grains of the dielectric material and birefringence from the concave/convex portions of the substrate allows increasing the birefringence quantity and making a thin film.

A robot apparatus includes a manipulator including a hand and an arm, a teaching apparatus that teaches operation of the manipulator, and a control apparatus that controls the manipulator that operates in a regular operation status or an erroneous manipulation avoiding status based on a control signal from the teaching apparatus. After determining whether a status of the manipulator is the regular operation status or the erroneous manipulation avoiding status, the control apparatus transmits a control signal for performing operation at a set regular speed to the manipulator in a case of the regular operation status, and the control apparatus transmits a control signal for performing operation at a speed lower than or equal to a safety speed that is set based on the regular speed to the manipulator in a case of the erroneous manipulation avoiding status.

A phase difference element capable of reducing reflection of incident light and a manufacturing method for the phase difference element are disclosed. The phase difference element includes a transparent substrate, an interface anti-reflection film groupand an obliquely vapor deposited film. The interface anti-reflection film group is composed by one or more of alternately high and low refractive index films, with the film thicknesses of the respectively films being equal to or less than the wavelength of light in use. The obliquely vapor deposited film is formed by a plurality of layers of a dielectric material. These layers are alternately obliquely vapor deposited from two directions differing by 180&#xb0; from each other. The refractive index of the interface anti-reflection film groupis higher than the refractive index of the transparent substrateand lesser than that of the obliquely vapor deposited film
