With the bee hive collapses, growers are desperate for pollenation options. Is anyone working on swarms of tiny flying robots to augment the bees? They could look for a certain color, poke around inside the flower for a moment, and move on to the next. When they need recharging, they fly back to their hive (the same reason bees fly back).
Of course, replacing germinators that run the seeds through their digestive systems would be a different problem.
