The Ingenious Whisky-Sniffing Robot Dog Transforming Distillery Operations

Introduction

In the heart of Scotland, Bacardi Limited has turned to an unlikely ally in its quest for quality: a Boston Dynamics robot dog equipped with an advanced ethanol sensor. This mechanical marvel, affectionately named Royal Barkla, is redefining age-old processes in whisky production.

The Leakage Dilemma

Leaking barrels have long been a headache in the spirits industry. Inside Dewar's extensive warehouses, where thousands of barrels age in harmony, a significant percentage are prone to leakage—both liquid and vapor. This not only impacts the quantity of whisky available but also alters its flavor profile.

“How do we make sure that when we come to get that cask, it's got as much whisky in it as possible?” asks Angus Holmes, Bacardi's whisky category director.

Bacardi's Dewar's brand alone can involve over 100 warehouses, leading to a massive challenge when leaks occur. It's not only about losing liquid; it's about safeguarding the integrity of the whisky that takes years to craft.

The Robotic Solution

Enter the National Manufacturing Institute Scotland (NMIS), which proposed an innovative approach: utilizing a robot dog capable of maneuvering through the tightly packed barrels. The Boston Dynamics Spot robot was suggested for its ability to navigate challenging warehouse environments.

For Royal Barkla to be effective, however, it required more than just mobility; it needed an enhanced sense of smell typically found in canines. A specialized 'nose' was developed, capable of detecting ethanol vapor, enabling the robot to identify problematic barrels without the need for human intervention.

Understanding Barrels and Leakage

Whisky barrels leak for various reasons, from the natural evaporation process, termed the “angel's share,” to physical damage caused during handling. Every year, around 2% of a cask's volume can evaporate, a normal part of whisky aging. However, excessive evaporation can lead to considerable loss and undesirable flavor changes.

As Bacardi faces the challenge of stacked barrels in densely packed warehouses, traditional methods—like knocking on barrels to gauge fullness—prove ineffective. This brings the robot dog's innovative capability into sharp focus.

Royal Barkla's Performance

The modified Spot was first meticulously tested to differentiate between normal and leaky barrels. The results were promising. When unleashed in a Dewar's warehouse, it significantly detected faulty casks—10% of those examined—demonstrating its potential.

“It moves with some pace. And it makes that horrible, horror-movie, floor-scratching sound as it chases after you,” Holmes humorously notes, reflecting on the robot dog's effective, albeit eerie, presence.

With its ability to log and report locations of leaky barrels, Royal Barkla adds a data-driven approach to whisky production. Bacardi is now able to better predict loss rates and maintain quality standards.

Future Innovations

While the success of Royal Barkla has been noteworthy, it is not without limitations. Its height restrictions mean it can only inspect barrels at the lower level of the warehouses. Yet, solutions are already in the works.

“We've found a spider robot that can climb,” explains Holmes, hinting at future enhancements for leak detection capabilities. Additionally, exploring the use of drones equipped for ethanol detection could naturally complement existing warehouse technologies.

Conclusion

Bacardi's proactive embrace of innovation highlights the evolving nature of traditional practices within the spirits industry. By welcoming technology like Royal Barkla into their operations, companies can safeguard their products and drive efficiency in operations.

As Bacardi's Andrew Hamilton notes, “If this kind of monitoring can be done in a repeatable, data-driven way, it adds real value.” The future looks bright as the spirits industry gears up for more technologically advanced innovations to address age-old challenges.
