A dual-joint multi-degree-of-freedom mechanical arm and a driving method thereof. The mechanical arm comprises a base, a driving mechanism, a large arm module and a small arm module. The driving mechanism comprises three bidirectional driving components mounted on the base; and the big arm module comprises a big arm push rod, a big arm central rod and an elbow joint universal plate. The comprises a wrist joint universal plate, a universal joint coupler, a small arm central rod, a small arm stretching rod and a wrist joint universal plate. The small arm stretching rod comprises a first connecting rod and a second connecting rod in transmission connection. Two-degree-of-freedom rotation of the big arm module and the small arm module connected in series is independently realized by using three bidirectional driving components fixed on the base, so that movement flexibility of an end executor in a working space is greatly improved.
