Minimalist Toy Robot Arm

a mounted base, one shoulder joint, a single straight upper-arm segment, one elbow joint, a single straight forearm segment, one wrist joint, then one hand. Exactly three joints total - shoulder, elbow, wrist - no additional bends, twists, or joints anywhere along the segments. Style: a single toy robot arm, playful muted colors, clean minimalist design. Porcelain white hand with two fingers and a thumb, silver knuckle ball joints. Reduced, toy-like industrial design - simple cylindrical and rectangular forms, oversized ribbed collar joints as the sole ornamental detail at each of the three joints only (not along the straight segments), high-gloss surfaces, two-tone color pairing per segment. No surface complexity, no realistic wear, no wires.
