I claim the ornamental design for a toy hydraulic robotic arm, as shown and described.
FIG. 1 is a front perspective view of a toy hydraulic robotic arm.
FIG. 2 is a rear perspective view of the toy hydraulic robotic arm of FIG. 1.
FIG. 3 is a side view of the right side of the toy hydraulic robotic arm of FIG. 1.
FIG. 4 is a side view of the left side of the toy hydraulic robotic arm of FIG. 1.
FIG. 5 is a front view of the toy hydraulic robotic arm of FIG. 1.
FIG. 6 is a back view of the toy hydraulic robotic arm of FIG. 1.
FIG. 7 is a top view of the toy hydraulic robotic arm of FIG. 1; and,
FIG. 8 is a bottom view of the toy hydraulic robotic arm of FIG. 1.
The dashed lines in various figures are for illustrative purposes only and form no part of the claimed design, and areas surrounded by broken lines form no part of the claimed design.
