The invention discloses a tripodal multidirectional mobile robot. The robot comprises a vehicle frame, a first foot, a second foot and a third foot, wherein the first foot, the second foot and the third foot are completely the same in the aspects of the structural composition, the part state, the connecting manner and the motion characteristic; and the three feet are horizontally spaced at 120 degrees on the vehicle frame, and a left leg board and a right leg board are perpendicular to the vehicle frame. The first foot, the second foot and the third foot are fixedly connected to the vehicle frame through connecting boards. The base structure of the first foot is a plane parallelogram four-bar mechanism, and the left leg board is relatively a rack in the four-bar mechanism; and the influences caused by singular positions in the motion process are eliminated through the structures of synchronous wheels and a synchronous belt. Two sets of foot installation holes are formed in the vehicle frame and correspond to two types of installation states of the tripodal multidirectional mobile robot, and two types of different moving strategies are achieved. The three feet are all fixedly connected to the vehicle frame through screws. By the adoption of the tripodal multidirectional mobile robot, the two installation states are achieved through the same assemblies, and the multidirectional motion of the robot is achieved in each state.
