Design Summary_Analysis Draft #2

In the article, "The RoboBees Flies Solo," Harvard John A. Paulson School of Engineering and Applied Science (2019) addressed researchers’ breakthroughs to a decade-long process of making a self-sustaining miniature flying autonomous vehicle.

According to the article, the researchers faced difficulty in finding the perfect balance between mass and power at such a tiny scale, where efficient flight is proven to be much harder to achieve.


Throughout the decade, researchers working on this project made several important and major additions to the design of the vehicle such as including an additional pair of wings and making adjustments to the actuator and transmission ratio and thus enabled them to “put everything we need on-board without using more power, ” as 
Jafferis stated in the article .

This particular change in the project allowed researchers to remove the power cord and add solar cells, allowing RoboBees to achieve a self-sustaining function and fly untethered.


Although the article provided us with the information on how untethered flight was achieved, it lacks explanations on how such changes would benefit users as well as assurance that with the implementation of such changes our society stand to reap more benefits


(support idea) In the article, it stated that it made changes the actuator and transmission ratio yet it did not mention how this can help in agricultural practices or for rescue efforts. The article only mentioned that by doing so they are able to generate more lift and "put everything they need on-board without using more power" but did not mention the purpose of taking such a step. This information will not be useful for farmers as they do not know what is the purpose of having a better actuator and transmission ratio. Although the actuator and transmission ratio provides more lift, it doesn't provide the speed needed for rescue effort and also it doesn't provide the ability to carry heavy load for agricultural effort. The article also doesn't provide us with how long the robot can last before running out of battery and also in order for the robot to maintain it's untethered flight, it needed "the power of three Earth suns to fly", which makes it difficult for it to be used for any kind of outdoor purposes as of present. Mario (2019) pointed out "drones can carry impressive loads, because it is their original purpose and these batteries are designed to handle that extra weight and so they don’t lose flight time" yet with so much limitations, mainly the battery life, Robobees wouldn't be able to handle carrying loads as it could barely even sustain itself.


The article also doesn't provide us with the assurance that the Robobees will be more beneficial than harmful. As bees are currently about to face extinction, the presence of such robotics bees may not aid our effort in trying to preserve these real small insects. Also similarly to when Albert Nobel first created dynamite with good intentions, Robobees which were created with good intentions might end up in the wrong hands and that could results in devastating results. As pointed by Perry (2016) mentioned "Will we become more lax with environmental regulations, now that we know we have a replacement for bees?" Similarly, Hyman (n.d.) mentioned "What’s stopping someone from using them for espionage? With their small and efficient bodies and ability to control themselves, they’d be very worthy allies for intelligence agencies and experts in corporate espionage." 


In conclusion, this article may have provided us with the scientific aspect of the changes, it however proved to be missing out on the practicality and impact of the changes when the changes are implemented.
