Buying Robotic Flowers
The National Institutes of Health spent $1.3 million in 2015 on flobots, which are, as the name implies, robotic flowers. Flobots use a sugar solution that mimics nectar, which is used to entice bees. Researchers use flobots to study the behavior of bees, which they say interact with flobots in a fashion similar to how they interact with real flowers.
