The invention relates to the technical field of robots, and discloses a shape memory alloy-driven tensioned integral bionic robotic fish which comprises a fish head, a tail fin, a fish bone and a driver. The fish head and the tail fin are bionic fish mechanism supporting elements based on fish-shaped streamline configuration, and the fish head, the fish bone and the tail fin are sequentially connected and fixed to form a bionic robotic fish mechanism main body; a fishbone mechanism is an integral tensioning mechanism and is composed of tetrahedron units based on a fishbone form, and each tetrahedron unit is connected to the next tetrahedron unit through two driving units in the horizontal direction, two fixing units in the vertical direction and four spatial rhombic supporting units so asto form the fishbone mechanism; and the driving system is an embedded fishbone mechanism driving system based on shape memory alloy driving, and is composed of a spiral shape memory alloy driving device, a controller and a control circuit. Bottleneck problems of low mechanism lightweight degree, segmented driving challenge and driving deployment of an existing bionic robotic fish under the condition that trajectory planning is met are solved.
