In a rotation device using a hydraulic actuator, a rotation angle range is increased. A placement member rotatably coupled to a rotary member has a projecting part on an upper face. A hydraulic actuator is arranged on a projecting face of the projecting part; the actuator and the rotary member coupled with a wire material. The projecting part is formed such that it becomes higher from a leading edge on the side of the rotary member to an intermediate portion in the longitudinal direction, and becomes lower from the intermediate portion to a trailing edge. Thereby, when fluid is supplied to the actuator and shortens the actuator length, a tip of the actuator moves along the projecting face of the projecting part, and is located high, separated from the upper face of the placement member such that the rotation angle range of the rotary member becomes large.

Disclosed is a tactile sensor which includes: a disk-shaped first strain generating section; plate-shaped second to fifth strain generating sections each provided as an extension of the first strain generating section extended from one of four substantially equiangular peripheral edge portions of the first strain generating section, each of the second to fifth strain generating sections being structured to support the first strain generating section as a leg thereof; first to fourth foot sections extended at a side different from a first strain generating section side respectively from the second to fifth strain generating sections; a diaphragm type first strain gauge attached to a discoid surface of the first strain generating section; and second to fifth strain gauges attached respectively to planer surfaces of the second to fifth strain generating sections, and a gripping robot using the tactile sensor for detecting contact pressure.

A plurality of trough displacement characteristics and drive signals for driving a drive unit for a trough are determined in association with each other and the speed of transport of the articles M transported by the trough having one of the trough displacement characteristics is also determined. Accordingly, a plurality of relationships between the transport speed of the articles M and the drive signal of the drive unit can be determined and, based on these relationships and merely by inputting a target speed to be attained by the articles M, the drive signal for the drive unit can easily be selected which enables the speed of transport of the articles M to attain the target speed. Also, since a travel quantity characteristics indicative of a correspondence between the quantity of travel of the articles and the driving time of the trough with respect to each of parameters of the plural coefficients of kinetic friction &mgr; is determined, the quantity of travel of the articles M with respect to the driving time of the trough can be grasped with respect to the plural coefficients of kinetic friction &mgr; taken as a parameter. Based on this, the coefficient of kinetic friction &mgr; between the desired trough and the articles M can easily be obtained from the quantity of travel of the articles measured by actually driving the trough for a predetermined time to transport the article M.
