The utility model discloses a multi-mode traveling mechanism for a robot, and belongs to the field of robot design. The multi-mode traveling mechanism comprises connecting supports and machine bodies, and a thigh steering engine is connected to the other end of each connecting support; thigh supports are fixedly connected to output shafts of the thigh steering engines, lateral swing steering engines are arranged in the thigh supports, and lateral swing supports are fixedly connected to output shafts of the lateral swing steering engines; shank steering engines are arranged in the lateral swing supports, shank supports are fixedly connected to output shafts of the shank steering engines, direct-current motors are arranged in the shank supports, and wheels are fixedly connected to output shafts of the direct-current motors. The sufficient through capacity of the multi-mode traveling mechanism on complex terrains is guaranteed; meanwhile, the wheels can be driven by the direct-current motors to rotate, the traveling speed of the multi-mode traveling mechanism on flat roads is increased, and the traveling rate of the robot is accordingly increased.
