This disclosure discloses a robot system including one or more work facilities and a teaching information database. The work facilities comprise a robot and robot controller. The robot controller controls the movement of the robot based on teaching information stored in a storage part. The teaching information database stores a plurality of types of the teaching information associated with work information. Each work facility includes an interface device configured to receive an input of search condition information, to search teaching information highly relevant to the search condition information among the plurality of types of teaching information, and to receive a selection of desired teaching information among one or more sets of the teaching information hit in the search. The robot system further comprises a first transferring part configured to transfer the teaching information from the teaching information database to the storage part.

Robot system and robot controller

An automatic preparation system according to an embodiment includes a case, a pressure regulator, and a plurality of robots. The case has a workspace inside thereof. The pressure regulator keeps a negative pressure inside the case relative to the outside. The robots are installed on a ceiling surface of the case and have respective arms. The robots bring the arms into cooperation to perform a preparation operation.

Automatic preparation system

A robot system according to an aspect of an embodiment includes a robot and a work bench. The robot has a plurality of joints including a first joint that is provided so as to be rotatable relative to an installation surface. On the work bench, a fixing part, by which a work member used in operations of the robot is fixed, is provided on a plate surface of a top plate with a rotation axis of the first joint serving as a normal line thereof, along a circular arc having a center at an intersection between the plate surface and the rotation axis.

Robot system and teaching method therefor

The present invention provides a sol of spinous inorganic oxide particles not containing coarse particles, in which particles having extremely homogeneous particles are dispersed in a solvent. An acidic silicic acid is added to a dispersion liquid of core particles to grow core particles, and then again the acidic silicic acid is added at the addition rate 1.2 to 1.8 higher than that in the previous step to prepare a sol of spinous inorganic oxide particles. Then the sol is subjected to centrifugation to remove coarse particles having the diameter of 800 nm or more, thus spinous inorganic oxide particles having peculiar form such as a spinous one being obtained.

Sol of spinous inorganic oxide particles, method of producing the sol, and polishing agent containing the sol

The present invention provides a sol of spinous silica-based particles in which silica-based particles having peculiar forms, spinous forms are dispersed in a solvent. The spinous silica-based particles have verrucous projections formed on surfaces of spherical silica-based particles. In the spinous particles, a value of the surface roughness (SA/SASAindicating a specific surface area measured by the BET method or the Sears method and SAindicating a specific surface area converted from an average particle diameter (D) measured by the image analysis method) is in the range from 1.7 to 10. Furthermore the average diameter (D) measured by the image analysis method is in the range from 7 to 150 nm.
