Abstract: A robot system includes a robot that includes a first robot arm provided with a first end effector, a second robot arm provided with a second end effector, a moving device on which the first robot arm and the second robot arm are mounted, and a control device; and a cart that includes a first support to which a plurality of wheels are attached, and a gripping portion. The first support includes, at a first end portion of the first support in a first direction, a recess for receiving a part of the robot. The control device causes the moving device to move the robot together with the cart while causing the first end effector and the second end effector to grip the gripping portion in a state where the part of the robot is fitted into the recess.

Abstract: A robot includes a self-propelled carriage, one or more robotic arms that are mounted on the carriage and allow an end effector to be attached thereto and detached therefrom, a storage that is mounted on the carriage and allows, to be stored, the end effector removed from the one or more robotic arms and the end effector to be attached to the one or more robotic arms, and a covering that is mounted on the carriage and covers the storage from above.

Abstract: A remote control device includes: a first arm; a second arm connected to a tip-end part of the first arm; two rotary bodies disposed at a tip of the second arm; a link structure including link members fixed to the two rotary bodies; and a user interface attached to the link structure. The two rotary bodies are independently and rotatably supported by respective coaxial drive shafts. The user interface is pivotable, with respect to the second arm, on each of mutually-perpendicular three axes passing through a center point of the link structure. The link structure is disposed at the lateral side of the rotary bodies so that the center point is located on an axis of the two drive shafts. The user interface is attached to the link structure on an axis of a rotation shaft passing through the center point.

Abstract: A marine hose has a twist coefficient 1900?K?2900 of fiber cords constituting a fiber reinforced member with three or four twisted filaments made of polyester, an interrelationship R between a predetermined elongation ratio E2 of a plurality of types of the fiber cords having different specifications and a hose elongation ratio E1 in a predetermined expansion test of each of marine hoses in which the fiber reinforced member including the respective fiber cords as constituent members is embedded as reinforcing layers is determined in advance. A threshold Th of the ratio E2 is set based on a standard value of hose elongation ratio E1 in the predetermined expansion test and the interrelationship R and the predetermined elongation ratio E2 of the fiber cords used as the reinforcing layers is set to the threshold Th or less.

Abstract: A robot system includes an actuator which operates a pair of finger members so that tip-end parts of the pair of finger members approach or separate to/from each other, a control device, and a pair of claw members. A base-end part of the claw member is provided with an engaging part. The tip-end part of the finger member is provided with a to-be-engaged part which is capable of engaging with the engaging part. One of the engaging part and the to-be-engaged part has a concave shape extending in a direction from the tip-end part of one of the finger members to the tip-end part of the other finger member. The control device operates the finger members so that one of the pair of finger members and the pair of claw members are located between the other pair, and then operates the pair of finger members so that each of the pair of finger members is brought closer to the corresponding claw member to engage the to-be-engaged part with the engaging part.

Abstract: A method of detecting the rate of corrosion of an existing steel structure installed in a corrosive environment is disclosed. The method includes treating a measurement surface of the member so that an AC impedance of the measurement surface, when electrochemically measured at a predetermined high frequency range of potential variation applied to the measured surface, takes a first valve within a predetermined range; and second value of the impedance is then electrochemically measured at a low frequency range of potential variation applied thereto. The difference between the first and second values is calculated to detect the corrosion-reaction resistance of the surface and the rate of corrosion is determined on the basis of the detected corrosion-reaction resistance and according to a pre-calculated relation between the rate of corrosion and the corrosion-reaction resistance.
