A German company has developed a groundbreaking method of dismantling old ships using a robot arm that utilizes water and sand. Bryce Lawrence, the operations director of Leviathan, explains that this innovative technology involves the use of multiple ship-cutting machines to recycle steel from decommissioned vessels. Not only does this method provide a more efficient and effective way of recycling ships, but it also prioritizes the safety of workers and aims to protect the environment. The traditional shipbreaking industry, as reported by the BBC, has been labeled as the “dirtiest and most exploitative in the world” due to its hazardous practices and pollution. Heavy metals from the ship-cutting process pose significant risks to workers, marine life, and the ocean ecosystem. It is crucial, therefore, to explore alternative options such as the implementation of robotic ship-cutting technology. These machines have the potential to revolutionize the shipbreaking industry, addressing the pressing need for safer practices and environmental sustainability. In this article, we will delve into the functioning of the robot arm, its advantages in terms of worker safety and environmental impact, and provide insights into other intriguing robotics projects.
How Does the Robot Arm Work?
A recent tweet from Interesting Engineering reveals that the robot arm employed by Leviathan integrates various established technologies. For instance, the robotic arm itself is similar to those used in car factories, while the waterjet technology is sourced from another German company called ANT AG. This waterjet system effectively combines high-pressure water and sand to cut through materials with exceptional precision. In fact, the technique is so accurate that it is utilized by bomb disposal experts to disable explosives. Till Weber, the general manager of ANT AG, explains that with this robotic arm system, the waterjet can be deployed from a distance of up to half a kilometer. Currently, Ukraine is already utilizing this technology. Bryce Lawrence emphasizes that this ship-cutting method requires a smaller workforce compared to conventional approaches. Additionally, the company has developed computer software that automatically determines the optimal cutting points on a vessel. Although certain drawbacks exist, such as the need for specialized equipment on a dry dock instead of a beach, Lawrence assures that a containment area will be in place to capture the water and toxic substances expelled during the cutting process. The water will be treated before the robot arm resumes its operations. Lawrence envisions a scenario where multiple robots start cutting the ship simultaneously from different locations, converging towards the center.
Benefits of Robot Arm Ship-Cutting
Compared to the traditional shipbreaking method that involves human workers using fuel-powered torches and sledgehammers, the implementation of robot arms represents a significant leap towards a safer and more eco-friendly approach. Workers in South Asia, where old vessels are typically sent for dismantling, are often subjected to hazardous conditions without proper protective gear, resulting in numerous fatalities. Moreover, this method contributes to the contamination of the ocean with heavy metals. In contrast, Lawrence asserts that Leviathan’s robotic ship-cutting technology significantly reduces carbon emissions. However, he acknowledges that competing with the low-cost shipyards in South Asia remains a challenge.
Other Fascinating Robotics Projects
Japan has also been at the forefront of captivating robotics initiatives. The University of Tokyo, for instance, launched the Jizai Arms project, which aims to examine human reactions to cyborg limbs. These robotic arms and fingers mirror the movements of the human controller. They are attached to a battery pack, similar to a backpack, that can support up to four limbs simultaneously. The most intriguing feature is the ability to attach one’s robot arm to someone else’s battery pack, enabling the control of an additional limb to assist in various tasks. According to the research paper on Jizai Arms, participants experienced a distinct sensation when attaching or detaching the robotic arms. They particularly noticed a strong impact when reducing the number of attached robotic arms. Another remarkable robotics project is the 15-foot-tall transforming mech called Archax, developed by tech company Tsubame in Japan. Archax functions as both a robot and a vehicle, standing at 14.8 feet tall when in robot mode and capable of lifting and carrying objects weighing up to 15 kg or 33 lbs. In vehicle mode, it deploys its wheels and reaches a speed of 6 mph or 9.65 kph.
In Conclusion
Leviathan, a German company, has pioneered a new method of ship dismantling that utilizes water and sand with the help of a robot arm. This innovative approach offers a safer and greener alternative to the traditional shipbreaking industry. By employing robot arms to cut up ships, the risk to workers is minimized, and the chances of harmful chemicals spilling into the environment are significantly reduced. Despite the need for further development, Leviathan’s creators believe that their technology holds immense potential for transforming the shipbreaking industry.
