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 advanceunder the dual effects of oscillation in the spring and a non-rigid ground surface, and the requirement on a lock release mechanism is reduced.
