This Slow-Moving Robot Efficiently Cleans Up Cigarette Butts

VERO: The Cutting-Edge Robot Tackling Cigarette Butt Pollution

Every year, approximately six million cigarettes are smoked globally, resulting in an astonishing 4 trillion cigarette butts being discarded improperly. These small remnants, despite the tobacco being long gone, pose significant environmental hazards. Each butt can leach over 700 toxic chemicals into the surroundings, making cleanup a critical issue.

Introducing VERO: A New Solution to an Old Problem

In response to this environmental challenge, researchers at the Italian Institute of Technology (IIT) in Genoa have developed a pioneering solution: VERO, which stands for “Vacuum-cleaner Equipped Robot.” This innovative robot is designed to address the pervasive issue of cigarette butt pollution with a novel approach.

The Design and Functionality of VERO

VERO employs a familiar four-legged robot design, specifically the Unitree AlienGo unit, which is adapted with a unique feature—a vacuum cleaner system. This vacuum system, worn as a backpack, includes a nozzle on each of its four feet. Each nozzle is custom-designed and 3D-printed to ensure that VERO can clean as close to the ground as possible without compromising its mobility.

Advanced Training and Neural Networks

Training VERO to effectively use its vacuum system presented a significant challenge. According to a paper published in The Journal of Field Robotics in April, the researchers developed a sophisticated neural network to process visual data from VERO’s onboard cameras. This network is crucial for distinguishing cigarette butts from other debris in cluttered environments and avoiding false positives.

Once VERO identifies a cigarette butt, it must navigate its environment to position one of its nozzles within suction range while maintaining balance with its other limbs. Unlike many wheeled robots, VERO is designed to handle uneven terrain, stairs, and other obstacles, requiring careful maneuvering to avoid tipping over.

Performance and Future Potential

VERO has achieved an impressive nearly 90 percent accuracy rate in various scenarios. While it may not be the fastest quadrupedal robot available, its specialized functionality and effectiveness in collecting cigarette butts make it a valuable asset for litter cleanup.

Beyond its current application, VERO holds potential for other uses. Researchers envision it assisting with tasks such as weed spraying in agriculture, infrastructure inspections, and even construction projects like rivet attachment or nail driving.

As the world continues to grapple with the environmental impact of cigarette butts, VERO represents a significant advancement in robotic waste management, offering a glimpse into the future of automated cleanup and maintenance solutions.
