The invention relates to a foot/wheel/track mixing four-wheel drive vehicle with dry adhesion and claws and a moving method thereof and belongs to the technical application field of robots. Each wheelfoot of the vehicle comprises an n-regular-polygon supporting ring (h) and an n-regular-polygon elastic track (i), and a damping shock absorption telescopic rod adhesion component is arranged betweeneach n-regular-polygon supporting ring (h) and the corresponding n-regular-polygon elastic track (i). When the vehicle encounters an obstacle, fixing caps (d13) are stressed to push damping shock absorption telescopic rods to extrude springs and air so that the springs and the air can be inward compressed, and accordingly the vehicle passes through the bumpy ground successfully; through dry adhesion material sheets (e1), the vehicle passes through the smooth slope with large gradient and small friction coefficient; through the fixed claws (g1), the vehicle can move up and down the stairs relatively easily and move on the bumpy ground with large gradient. The foot/wheel/track mixing four-wheel drive vehicle can achieve multiple kinds of complex moving functions and have good all-terrain adaptability and obstacle crossing characteristics.

The invention provides a dry adhesion and claw combined quadruped multiphibious robot and a bionic motion method and belongs to the field of robots. A body main body of the dry adhesion and claw combined quadruped multiphibious robot comprises a front foot supporting frame (3), N series-connected body Z-axis steering engines and a rear foot supporting frame (18); a head neck structure comprises ahead Y-axis steering engine (2) and a camera (1); a tail structure comprises a tail X-axis steering engine (26), a tail X-axis steering engine U-shaped connecting piece (27), M series-connected tail Z-axis steering engine and a tail fin (31); and each foot structure consists of a foot Y-axis steering engine, a supporting foot, a paddle, a claw and a dry adhesion material. The dry adhesion and clawcombined quadruped multiphibious robot can satisfy self-adaptive requirements of a non-structural topographic water surface-land surface under a natural environment; and meanwhile, the dry adhesion and claw combined quadruped multiphibious robot can adopt dry adhesion to perform large slope wall surface climbing on a smooth surface and can also adopt the claw to perform large slope wall surface climbing on a rough surface; and the dry adhesion and claw combined quadruped multiphibious robot can be used as a dry adhesion and claw four-wheel-foot-paddle-driven multiphibious robot on an all terrain multiphibious cross-country mobile platform under the natural environment.

The invention relates to a pultrusion production traction device and method for fiber enhanced composite bent sectional materials based on the traction rate differential motion. The traction device iscomposed of two traction chucks and a rack track. Each traction chuck is composed of a sliding clamping plate, a fixed clamping plate, a vertical guide rail, a sliding connecting piece and a jack. The rack track is a circular curve track and is internally provided with roller shafts, and the motion direction of the traction chucks can be limited. In the traction chuck motion process, through thejack jacking pushing speed differential motion and the rack track limitation, the traction chucks can do plane rotation along the circular curve, and needed bent sectional materials are produced. According to the pultrusion production traction device and method, the motion principle is clear, the equipment structure is simple and feasible, and the pultrusion production traction device and method can be applicable to pultrusion production of bent sectional materials different in radius.

The invention relates to a pultrusion production traction device and method of fiber reinforced composite material curved profiles. The traction device is provided with a rack platform; a rack is provided with two rows of slide rails distributed in a fan shape; each slide rail is provided with a vertical roller; the rollers can move along the slide rails; the two rows of rollers are arranged alongthe circular curve; two guide blocks are arranged between the rollers; and the guide blocks conduct plane movement along the track formed by the rollers under pushing of a jack. The guide blocks areconnected with a chuck through vertical connection shaft to form a traction portion jointly, the vertical connection shafts can drive the chuck to rotate, and the chuck is composed of an upper clamping board, a lower clamping board and a vertical guide rail. Through plane movement of the guide blocks and the rotation of the vertical connection shafts, the chuck can conduct plane rotation along thecircular curve.
