The present invention relates to a flexible robotic arm based on the coupling of memory alloy and pneumatic artificial muscle, wherein the flexible robotic arm comprises a fixed disk, a spacer disk, an airbag, a center rod, a base and an air supply pipe. The fixed disk is a circular thin disk, which is installed at the end of the flexible robotic arm and is used to fix other components. The spacer disk is also a circular thin disk, which plays a supporting role in the middle of the flexible robotic arm. The airbag is a silicone thin shell structure, which provides power for the movement of the flexible robotic arm. The center rod material is nickel-titanium alloy, which has shape memory function, and the stiffness is enhanced after heating, thereby improving the stability of the flexible robotic arm. The base is a circular disk, which is used to fix other components and connect other control devices or power sources. The air supply pipe is rubber soft, which provides power by supplying air to the airbag. The present invention realizes the movement and stiffness change of the flexible robotic arm, reduces vibration and improves stability through the cooperation of the airbag and the shape memory alloy center rod.
