The invention provides an underwater robot arm with variable buoyancy. The underwater robot arm comprises a box body, a pressure cylinder, a first electric telescopic rod, and a piston. The two sidesof the pressure cylinder are installed in the box body through fixing rods. The bottom of the first electric telescopic rod is fixed to the bottom of the inner wall of the pressure cylinder. The bottom of the piston is fixed to the top of the first electric telescopic rod. According to the underwater robot arm provided by the invention, float bowls are symmetrically distributed on the two sides ofa box body; the area of the air cavity in each flow bowl is adjusted, so that the buoyancy of the box body on the two sides and the whole buoyancy of the float bowl are conveniently adjusted and controlled; the mechanical arm assembly on the box body can be conveniently moved up and down, so that the depth of the underwater robot arm is conveniently adjusted; the structure is simple, use is convenient, adjustment and operation can be conducted at different underwater depths, so that different use requirements of users are met.
