May 2011: Starting from the color sorter arm, I built this LEGO industrial plant, realizing a desktop-scale model of an automatic warehouse. It features the 4DOF palletizing manipulator robot, and an automatic guided vehicle that moves products (colored balls) from the picking stations to the dropping stations, implemented as gravity racks. The development took two months full time.
Your company can use such LEGO industrial model to attract people to your fair booth, for simulation and training purposes.
