The invention provides a three-dimensional space maneuvering bionic robot fish and a buoyancy adjusting device. The three-dimensional space maneuvering bionic robot fish comprises a main body structure, a propeller, a buoyancy adjusting device and pectoral fins. The buoyancy adjusting device comprises a buoyancy cylinder and a volume adjusting mechanism arranged in the buoyancy cylinder, the two ends of the buoyancy cylinder are sealed through watertight hatch covers. Water inlet and outlet holes are formed in two ends of the buoyancy cylinder; the volume adjusting mechanism comprises steppingmotors, lead screws, a movable support and a piston; the piston is fixed to one end of the movable support; a disc with a threaded hole in the middle is fixed to the other end of the movable support;the tails of the two stepping motors are fixedly connected; an output shaft of each stepping motor is connected with one lead screw; and the lead screws are matched with the threaded holes of the disc. The device can ensure that the robotic fish rapidly floats up and dives down, and effectively solves the problem that the three-dimensional space maneuverability of the current robotic fish is weak.
