What do robots and birds have in common? They both have difficulties recognizing transparent objects. Because they have their pitfalls: other objects can be reflected on them, they can dazzle or be completely transparent. Researchers at Fraunhofer IOF had an idea of how they could enable robots to "see" glass. In our "Recognize and understand" experience world, we show you the technology that will enable robots and machines to recognize and interact with transparent objects in the future. You will also see an ultra-compact multispectral camera that makes the invisible visible to the human eye. This camera can be used to determine the degree of ripeness of fruit or, in future, to observe when a plant needs water.
