The invention discloses a three-section machine body type hexapod robot with the transportation function and the operation function fused, and belongs to the technical field of robots. The problems that the rigid machine body structure of an existing hexapod robot is fixed and the function of the robot is single are solved. A front trunk is connected with a middle trunk in a rotating mode through front driving joints, the front trunk and linear drivers of the front driving joints are hinged, and the linear drivers of the front driving joints are hinged to the middle trunk. The middle trunk is connected with a rear trunk in a rotating mode through middle driving joints, the middle trunk and linear drivers of the middle driving joints are hinged, and the linear drivers of the middle driving joints are hinged to the rear trunk. A self-discharging tipping bucket is connected with the middle trunk in a rotating mode through rear driving joints, the self-discharging tipping bucket and linear drivers of the rear driving joints are hinged, and the linear drivers of the rear driving joints are hinged to the middle trunk. A front left leg and a front right leg are connected with the front trunk, a middle left leg and a middle right leg are hinged to the middle trunk, and a rear left leg and a rear right leg are hinged to the rear trunk. The hexapod robot is high in topographical change adaptive capacity and high in motion flexibility and stability.
