Concept


The LIAA scenario

Today’s manual assembly areas consist of different workplaces. Each workplace contains part supply areas, tools and fixtures to conduct specific assembly steps on a set of predefined products. Depending on the current order situation workers use these workplaces to assemble products in varying sequences and batch sizes applying many different assembly skills. Some of these are complex and require superior human sensing capabilities; others are simple and purely repetitive. In today’s manual assembly areas all of them are conducted by humans. Therefore, layout, workplaces, part supply, tools and fixtures are optimized for human utilization. This constitutes a big obstacle for the introduction and utilization of robots even for the simple and repetitive jobs. LIAA will overcome this obstacle with a holistic approach that considers all aspects relevant to enabling human-robot symbiotic assembly.


The LIAA use-cases

The LIAA framework addresses the following use cases in an assembly workshop with changing work load and different assembly workplaces:

  • Human OR robot work consecutively at a common workplace: depending on the current work load either a human is assembling small quantities of one product at a workplace or a robot is manually put into place if the product is required in high numbers. Human and robot use the same tools and fixtures.

  • Human AND robot share a common workplace: depending on the current work load, either a human is assembling small quantities of one product at a workplace or a robot is additionally put into place to support the human if high numbers are required. Human and robot then divide the required assembly steps according to their respective strengths: the robot does the simple and repetitive jobs while the human takes over the demanding steps requiring advanced sensing and reasoning capabilities.


Lean

LIAA aims at the development of low-cost, low-complexity robot systems. Low-cost robot systems are enabled by the availability of low-cost robots for about 20.000 € (e.g. Universal Robot UR5, Rethink Robotics Baxter), low cost sensor systems for about 200 € (e.g. Kinect-like sensors), by tool sharing between human and robot and by integrating the human in the loop (symbiotic assembly). The human in the loop will eliminate complex and costly application-specific robot tools and fixtures otherwise required by the robot system to cope with the types of unstructured environments that are easy for humans.


Intelligent

The LIAA robot systems require advanced software functionality to be productive in close cooperation with a human worker. Therefore, an intelligent programming and control system is the core of a LIAA robot system and therefore the focus of the efforts within LIAA. Of course, this complexity will be hidden from the worker interacting with a LIAA robot system.
