The LIAA framework at a glance

The LIAA framework constitutes a holistic approach that covers all aspects required to allow symbiotic human-robot assembly come true:

  • Symbiotic Workplace Design

    Assembly workplaces must be designed such that they can be used by robots and humans likewise. This involves the development of criteria and metrics to measure a workplace’s suitability for symbiotic assembly, safety concepts and finally design principles for symbiotic workplaces. A Computer-Aided Symbiotic Workplace Design Tool will integrate all results and support the user in the design of symbiotic workplaces.

  • Task Assignment and Dynamic Scheduling

    Assignment and Dynamic Scheduling takes care of assigning job to humans and robots in a way such that the assembly workshop is operating most productive. This involves the development of a Uniform Task Description that can be translated into instructions for humans as well as robot programs, resource models for humans and robots; algorithms for resource assignment based on capabilities and scheduling algorithms taking into account current work load. An Assembly Workshop Symbiotic Planning Tool will integrate all results with the aim of using the available resources (humans, robots, workplaces) as productively as possible.

  • Symbiotic Robot Execution

    To be productive when applied to a workplace the robot must adapt its behavior instantaneously based on situation awareness and prediction. This involves the development of models describing the current state of a symbiotic workplace; sensor based human activity recognition algorithms; human activity prediction algorithms; instantaneous program adaptation strategies to avoid unsafe situations; exception handling and error recovery. All results will be integrated into a Symbiotic Robot Execution System that controls the low-level functions of the robot during assembly execution.

  • Human-Robot Interaction

    Augmented Reality (AR) devices in combination with an AR visualization and simulation environment give the human worker all relevant information about the current situation during operation; AR-based Human-Robot-Interfaces and natural 6DoF interaction allows the user to interact with the robot in every situation in an intuitive and productive way.

  • Robotic Assembly Skills

    A skill formalism and skill instances based on this formalism are the basis for robotic assembly, special skills for local referencing and calibration and a work flow to generate robot programs automatically based on a task description and skill instances is key to deploying robots into symbiotic workplaces in short time and without expert knowledge.


Architecture

The figure below gives an overview of the (simplified) software architecture of the LIAA framework. The architecture reflects the above described core aspects of the LIAA framework (that were also the source for the work package definition).
