A multi-degree-of-freedom robotic arm includes a body mechanism, an actuator mechanism, and a control system. The body mechanism has a first end rotating around a vertical heading axis and a second end rotating around a horizontal first pitch axis. The actuator mechanism is installed at the second end of the body mechanism and includes: a first roll mechanism rotatably installed at the second end around a first roll axis perpendicular to the first pitch axis; a second roll mechanism rotating around a second roll axis and installed with an end actuator; and a pitch mechanism installed at a junction between the first roll mechanism and the second roll mechanism so that the second roll mechanism rotates around a second pitch axis with respect to the first roll mechanism. The control system controls and drives an operation of the body mechanism and the actuator mechanism.
