Abstract: A self-propelled vehicle is provided, including a rotatable power base comprising two main wheels and at least one auxiliary wheel, the two main wheels being connected to two sides of a power base, the at least one auxiliary wheel being disposed underneath the power base, wherein the rotatable power base further includes a differential for connecting and controlling the two main wheels, thereby, the rotatable power base can be rotate 360 degrees; a connecting module having a first end and a second end, the first end being connected to the rotatable power base; a carrying module connecting to the second end of the connecting module; and a control module being secured to the carrying module for controlling operations of the rotatable power base and the connecting module. Accordingly, time spent on standing and walking by operators can be reduced while increasing work efficiency.
