The invention relates to a jumping robot based on the tripping energy-storing-releasing mechanism. The jumping robot comprises a horizontal supporting plate. A bouncing leg is arranged in the center of the supporting plate. The upper portion of a pedal foot of the bouncing leg is connected with a spring guiding column and a tripping rod. A power spring is arranged outside the spring guiding column in a sleeved mode. The lower end of the power spring presses the pedal foot, and the upper end of the power spring abuts against the supporting plate. A tripping contact is arranged at the upper end of the tripping rod. A horizontal hook is arranged at the upper end of the spring guiding column. A stand plate is arranged above the supporting plate. The stand plate is hinged to a cam, an L-shaped connecting rod, a tilting rod and a tripping piece. The upper end of the pedal foot is hinged to two connecting rods. The upper ends of the two connecting rods are connected with the end of a parallelogram connecting rod mechanism through a rotating pair. The parallelogram connecting rod mechanism is fixedly connected with a horizontal rack which is meshed with a gear to form a gear-rack transmission mechanism. The upper ends of the two connecting rods are connected with a vertical pushing rod through a rotating pair. The pushing rod is connected with the supporting plate. The upper end of the pushing rod is hinged to the connecting rod which is hinged to a dead point pushing rod. The dead point pushing rod is arranged in a vertical dead point pushing rod guiding sleeve in a hollow-sleeve mode.

The pilehammer has the advantages of completely preventing the landing gear from colliding with the cylinder hammer and the top transverse beam in a work process, automatically hooking and decoupling the landing gear and facilitating the operation.

The invention discloses a six-bar bouncing combined-type wheel-leg mobile robot, which comprises a wheel-type moving mechanism, a bouncing mechanism, a front and rear swing arm mechanism and a holder mechanism. A six-bar rhombic nonlinear tension spring bouncing and locking mechanism is used, the bouncing height of the mobile robot is increased, the mechanism is prevented from bouncing in advance under the dual effects of oscillation in the spring and a non-rigid ground surface, and the requirement on a lock release mechanism is reduced. The front and rear swing arm mechanism adopts a structure of two front swing wheel legs and a single rear swing wheel leg. Since the swing arm shafts of the front and rear swing arm mechanism are not coaxial with wheels, the limitations to arm length are fewer, and the ability of crossing over ditches of the mobile robot is greatly enhanced. Besides, by adopting the design of the front and rear swing arm mechanism, the occupied space is few, and enough installation spaces are reserved for subsequent upgrade needs. An auto-resetting function and an obstacle leaping function can be realized. A charge coupled device (CCD) observation table is integrated with sensors for postures, positions, directions and the like and is installed in a holder which can be lifted up and lowered down. Under field natural environments, the environmental adaptability and the ability of crossing over obstacles are very high.
