Cell phones proliferated in the early aughts in America just as Colony Collapse Disorder began to claim large swaths of our bee population, and some thought perhaps there was a connection. But it was just correlation, not causation. Bees seem instead to be stressed by nicotine-derived pesticides and other still-to-be-determined factors. From Dina Spector at Business Insider, an article about RoboBees, one proposed solution to the problem but probably not the best one:

“Honeybees, which pollinate nearly one-third of the food we eat, have been dying at unprecedented rates because of a mysterious phenomenon known as colony collapse disorder (CCD). The situation is so dire that in late June the White House gave a new task force just 180 days to devise a coping strategy to protect bees and other pollinators. The crisis is generally attributed to a mixture of disease, parasites, and pesticides. 

Other scientists are pursuing a different tack: replacing bees. While there’s no perfect solution, modern technology offers hope.

Last year, Harvard University researchers led by engineering professor Robert Wood introduced the first RoboBees, bee-size robots with the ability to lift off the ground and hover midair when tethered to a power supply. The details were published in the journal Science. A coauthor of that report, Harvard graduate student and mechanical engineer Kevin Ma, tells Business Insider that the team is ‘on the eve of the next big development.’ Says Ma: ‘The robot can now carry more weight.’

The project represents a breakthrough in the field of micro-aerial vehicles. It had previously been impossible to pack all the things needed to make a robot fly onto such a small structure and keep it lightweight.”

Just one more post about delivery drones, and then I promise I’ll stop for awhile. The opening of Alvin Powell’s Harvard Gazette interview with engineering professor Robert Wood, who sees not technical obstacles to such delivery systems but bureaucratic and legal ones:

Harvard Gazette:

Amazon’s Jeff Bezos said he’s serious about using flying robots to deliver packages, saying that the technology is almost there — within four or five years — and that Federal Aviation Administration [FAA] regulations might permit it by 2015. What was your reaction when you heard this?

Robert Wood:

The technology is actually quite close. My first reaction is that the technology is much closer than overcoming the FAA and liability barriers. Of course they will need to refine the vehicle and controller designs to first ensure safety and, second, to verify efficiency and efficacy of this method.

Harvard Gazette:

How realistic is the scenario of using flying robotic drones to deliver packages? I’m sure it seems completely ‘out there’ for most of the public. Is it?

Robert Wood:

I think technically this is quite reasonable. In a laboratory setting, moving an object from one position to another using a flying vehicle is something that has been demonstrated. When you start to move this out of a lab setting, there are tremendous challenges, including weather, turbulence when moving around buildings or objects, dynamic objects in the environment such as people or cars, and imprecise or unreliable sensor information. But the robotics community is working on solutions to all of these topics — [like] the ‘self-driving car’ — so I suspect the answers are not far off.”
