A robot system for carrying out a plurality of operations during assembly or maintenance of an aircraft or spacecraft includes a first robot having a base portion, a movable robot arm having a first coupling portion, and a first control means for controlling the robot arm, a plurality of second robots having movement means, a drive portion operable to drive the movement means, a tool portion having a tool for carrying out a specific one of the operations, a second coupling portion adapted to be selectively and releasably coupled with the first coupling portion in a predetermined positional relationship, and a second control means for controlling the respective second robot. The first and second control means are adapted to control the drive portion of one of the second robots and the robot arm to couple the first coupling portion and the respective second coupling portion in the predetermined positional relationship.

Robot system and method of operating a robot system

To provide an aircraft wing which has both high bending flexibility in the wing chord direction and high capacity to maintain the wing shape in the wing span direction, and to which morphing aircraft technology can be applied in the high-speed regime where aerodynamic forces are high. The wing is formed by arranging a plurality of CFRP rods having maximum anisotropic stiffness in the axial direction, so as to be parallel to the wing span direction, and filling the gaps between the CFRP rods with an elastic material.

Aircraft wing, aircraft wing composite material, and method of manufacture thereof

The resin in a fiber-reinforced resin material that uses a single fiber reinforcing ply or a number of fiber reinforcing plies for reinforcing the resin material is reinforced by dispersing carbon nanofibers therein, whereby a fiber-reinforced composite resin material having improved strength such as compressive strength is provided. In a carbon nanofiber-dispersed resin fiber-reinforced composite materialan uncured resinhaving carbon nanofibersdispersed therein is impregnated into a number of fiber reinforcing plieslaid one upon another. Upon curing the resinthe strength of the matrixitself is increased through the carbon nanofibersdispersed in the resinMoreover, the fiber reinforcementand the resinare joined together strongly by the carbon nanofibersand hence the strength of the composite material, for example the compressive strength, which hitherto has been dependent on the strength of the resinonly, is improved.
