Craft a wooden R2D2 robot, constructed from a repurposed wine barrel, infused with a steampunk aesthetic. The robot's cylindrical body is fashioned from rich, polished oak staves, adorned with intricate brass gears, cogs, and rivets. A series of copper pipes and valves snake across its surface, contributing to its industrial, retro-futuristic charm. The domed head of the robot features a gleaming brass periscope and a set of glowing, amber-hued lenses that evoke a sense of antiquated technology. Whiffs of aged wine linger in the air, adding a unique olfactory dimension to the scene. The robot stands proudly on iron wheels, exuding a blend of elegance and rugged mechanical prowess, ready to embark on its next daring adventure in a whimsical, alternate universe.
