Abstract: An information processing apparatus includes a storage that stores operation explanation information for explaining task contents to be performed on the information processing apparatus, an operation explanation display controller that displays operation explanation information related to a specific task to be performed on the information processing apparatus, a task information acquirer that acquires information about a task performed on the information processing apparatus when the operation explanation information is displayed, an erroneous task determiner that determines that an erroneous task is performed on the information processing apparatus when the acquired information about a task differs from contents information of the specific task indicated in the displayed operation explanation information, and a warning processor that notifies warning information indicating that a task different from the specific task indicated in the displayed operation explanation information is performed when it is determi

Abstract: Provided is a grip tool that allows detecting a slip of an object. The grip tool includes a pair of grip portions that sandwiches to grip an object; an opening/closing mechanism that opens and closes the pair of grip portions; and at least one sensor unit disposed in one or both of the pair of grip portions. The sensor unit includes a plurality of force sensors disposed in a predetermined distribution. The plurality of force sensors each have a function of measuring forces in triaxial directions received from the object. The sensor unit can measure a load distribution received from the object. The slip of the object is detectable based on the load distribution.

Abstract: A cutting tool is described comprising a cutting insert with an upper surface, a lower surface, a side surface, and a cutting blade formed at the intersection of the upper surface and the side surface, and a holder comprising an insert pocket to which the cutting insert is attached. The cutting insert is attached to the holder in such a manner that the cutting blade projects outward from the front end surface and the outer peripheral surface of the holder. The holder comprises in the outer peripheral surface on a rear end side with respect to the cutting blade a concave curve-shaped first wall surface portion that extends from the vicinity of the insert pocket toward the rear end side. The lower end of the front-end-side edge of the first wall surface portion is disposed at a lower position than the cutting blade.
