  • Leader : David Daney
  • Type : team
  • Research center(s) : Bordeaux
  • Field : Perception, Cognition and Interaction

  • Inria teams are typically groups of researchers working on the definition of a common project, and objectives, with the goal to arrive at the creation of a project-team. Such project-teams may include other partners (universities or research institutions)

Team presentation

This research project is part of the field of collaborative robotics. It is motivated by the following societal and economic issues:

● The preservation of know-how in the production and assembly companies,
● The preservation of human in the industry: less hardship, musculoskeletal disorders (MSDs),
● Productivity Improvement: Synthesize a gesture of production; delegate manipulation tasks and dexterity constraints to an assistance system in order to focus the operator on cognitive tasks,
● the factory of the future.
The scientific issues addressed are:
● Identify and analyze the cognitive and physical fragilities of the operators.
● Evaluate the cybernetic organism.
● Design the cobotic system.
The scientific objectives are:
● Measure, analyze and model the activity: model the knowledge, behaviors, interactions and uses; to better understand the place of the human within the production apparatus.
● Model the operator's gesture: propose a modeling of the human that takes into account the uncertainties and variability of the parameters; to include in this model psychic and cognitive constraints.
● Measure, analyze, synthesize the gesture: develop new evaluation indices that synthesize the properties of the gesture, its ergonomics and its influence on the task; identify the constraints leading to underperformance of the operator or the difficulty of the action; propose corrections learned or deduced from the model.
● Design a robotic system: use existing cobotic architectures to design a collaborative production cell (tasks, sharing of authority),
● Understand the needs of the operator in terms of assessment and cognitive and physical assistance.
● Design and control industrial robotized operator assistance systems.
● Design of cobots coupling physiological, biomechanical evaluation and operator performance in physical and cognitive symbiosis with its robotic assistance system.
Ultimately, the project must allow better penetration of cobots in our industries by demonstrating a quantifiable added value of the human / robot couple on the workstations.

Research themes

We describe three lines of research that structure the research themes of Auctus. The first "analysis and modeling of behavior" aims to analyze, model and then merge the physical and cognitive constraints to which industrial operators are subjected: they come from the way work and tasks are split and organized within a business, from the activity and the environment to the ergonomic, biomechanical, musculoskeletal constraints of the human. The second theme "human / cobot coupling" focuses on the evaluation and optimization of the robot / human pair. Finally, the third uses previous evaluation indices to design operator perception and assistance systems.
  • Analysis and modeling of behavior
