  4. ILIAD in a nutshell Why the intermediate is the big step

  5. Concept image More quickly changing market needs, unforeseeable trends, shorter product life cycles, …

  6. Flexible intralogistics needed • Today’s highly automated goods-to-man solutions • require dedicated warehouses, • are unsuitable for fresh food, bulky goods, etc. • ILIAD’s aim is to provide solutions for flexible intralogistics for the transition to automation in shared spaces.

  7. Flexible intralogistics needed Therefore we need intralogistic systems that are F-RE-SE–QUD–SA-EFF! (1) highly flexible, (2) rock-solid reliable, (3) self-optimising, (4) quickly deployable and (5) safe yet (6) efficient in environments shared with humans.

  8. Approach Safety and efficiency by Easy deployment with long-term learning and semantic mapping prediction of patterns Flexible manipulation Human safety-aware AGV fleets: On-line, self-optimising safe and legible motion planning, fleet management human detection and tracking, mutual communication of intent

  11. Demonstrators • Demos at key stakeholders from food distribution sector. • Distribution of fresh food products particularly challenging: • sensitive products, • short shelf life, • rapid response to consumer needs. • Food industry largest manufacturing sector in EU: 4.2 million jobs.

  12. Orkla Foods Not always well-defined aisle environment Heterogeneous and brittle (and sometimes large or heavy) items to pick.
