The Objectives & Aims
Partial automation using a collaborative robotic system
The CoboTank project is implementing partial automation using a collaborative robotic system, a so-called cobot, to support the loading process of tankers in the first work strand.
For example, the correct hose used for loading and unloading can be gripped by the cobot, transported across the pontoon and the tank lid opened immediately before the hose is handed over to the crew. A cobot is a robotic system that operates in cooperation with a human and is also guided by the latter.
The human operator is physically and mentally relieved and only takes on planning, guiding and monitoring tasks, while the cobot performs the physically demanding, often repetitive, monotonous or risky tasks - such as transporting heavy loads - precisely and safely.
In the application for loading and unloading tankers, the operator instructs the semi-automated cobot to carry out the respective tasks and uses an intuitive operating concept to do so, e.g. by guiding the cobot using a handle. The operator can react quickly to changes in the situation and interact with the crew on board. Partial automation using a cobot brings added value in following fields:
- an acceleration of the processes (efficiency),
- increased process reliability (security),
- the best possible occupational safety (safety), and
- improvement in ergonomic aspects (physical and psychological) (ergonomics).
In addition to the cobot, a robot arm is being developed in a second work strand to implement a fully automated refueling process. However, the complexity of this solution requires an extensive research agenda. Furthermore, the implementation of automated refueling processes on today's tankers is currently not possible due to the environmental conditions and the applicable standards and laws. Therefore, building on the findings of the first strand of work on partial automation, the concepts for full automation will first be developed and implemented in a scaled demonstrator in the research environment. The scaled environment allows the safe testing of innovative concepts for control technology, path planning, environment detection and navigation in the application of automated loading and unloading of tankers. In addition, requirements for the tanker and the wider environment that support the technical implementation of automated loading and unloading will also be developed and formulated as part of this line of work. At the same time, the corresponding guideline work will be prepared with the partners.
An interdisciplinary approach involving engineers, psychologists and business economists ensures the effectiveness and acceptance of the solutions in equal measure.
Cobots are considered “colleagues of steel”.
Cobots must not pose a risk to humans in the context of cooperation. They are therefore designed to work together with humans without physical barriers or safety enclosures. Designed with intelligent algorithms and control strategies, they can recognize hazards for the operator and the environment and warn the operator or block dangerous operating instructions (such as imminent collisions).
