Abstract
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.
