The invention relates to a test system and method for gecko aerial statue adjusting and landing motions and belongs to the field of biomimetic motion test. The system comprises a landing plate (8) and a sliding beam (14) and further comprises a three-dimensional force sensor array (9), a high-speed camera, a computer control terminal (18) and a force sensor data acquisition system (6) which are arranged on the landing plate (8). A gecko staying space formed by a transparent plate (13), a left turning plate (17) and a right turning plate (19) is formed below the sliding beam. By means of the system and the method, gecko aerial moving posture regulation and landing buffering biomimetic mechanism researching can be developed effectively, and a new posture control and landing collision biomimetic method is provided for gecko space robot posture regulation and landing research.

The invention provides a variable-volume bionic fish main body structure, a bionic finish and a motion regulation method and belongs to the field of robots. The variable-volume bionic fish main body structure comprises a body supporting plate 11, a fish tail assembly, an attitude adjusting assembly and a volume adjusting assembly. The attitude adjusting assembly comprises a nut counterweight block(20), a first screw rod (21) and an attitude adjusting motor (23); and by making the nut counterweight block (20) move forwards and backwards, the bionic robot fish is adjusted to bend forwards and backwards. The volume adjusting assembly comprises a nut slide block (34), a second screw rod (35), a volume adjusting motor (36), a variable-volume connecting rod assembly which is positioned on the left side of the body supporting plate (11), and a variable-volume connecting rod assembly which is positioned on the right side of the body supporting plate (11); and by making the nut slide block (34) move forwards and backwards, the volume change of the bionic robot fish is adjusted by using a first connecting rod and a second connecting rod so that the buoyancy is changed to realize a rising and descending function. By controlling a steering engine (14) to rotate, a fish tail (12) swings from side to side. The variable-volume bionic fish main body structure has the advantages of simple structure, clear motion principle and convenient motion realization.

The invention discloses curve profile pultrusion production traction equipment and method based on a traction speed differential motion. The equipment comprises multiple slide rails mounted on a frame; the slide rails are arranged at intervals in a fan form; rollers are mounted on the slide rails; the rollers are distributed in two rows; each row of the rollers are arranged along the same sectionof arcs; first traction chucks and second traction chucks are arranged between two rows of the rollers, and move along rails formed by the rollers; the first traction chucks are positioned in outletsof curing molds; in the moving process of the traction chucks, through ejecting speed differential motions of jacks and limitations of the rollers, the traction chucks are rotated in a planar mode along round curves; and meanwhile, through movement of the rollers on the slide rails, the radiuses of the round curves are adjusted to continuously produce bent profiles with different curvature radiuses so as to realize needed curve profiles formed by multiple round curve profiles. The production equipment is simple and convenient, and is suitable for pultrusion production of bent curve profiles with different types.
