It turns out that bees also have "right handed" and "left handed", and it is expected to be applied also to Autonomous Flight Technique of Drone

Studies that there are "right-handed" and "left-handed" individuals who prefer either right or left in a bee as some people have a pen with a right hand or others have chopsticks with their left hand It is clarified by. By further advancing this research, it is expected that it will be useful for autonomous flight such as drone in the future.

Brisbane researchers discover bees can be left or right-handed - ABC News (Australian Broadcasting Corporation)

This research was conducted by a research team at the University of Queensland in Australia. We investigated left and right biases seen when bees fly by avoiding obstacles in the front and it has been discovered that individuals with a high probability of choosing either left or right exist at a certain rate .

Professor Mandyam Srinivasan, who led the research team, prepared a long tunnel-like experimental facility, and introduced sugar water at the innermost side and induced the bee to enter the back. In the tunnel there is a board with two openings, and when the bee goes backwards, the choice between the left and right is picked up with a camera attached at the top and recorded.


In the experiment, a plurality of openings having the same size on the left and right or one having a larger one is prepared. Approximately 120 bees were marked with acrylic paint made by Tamiya so that individuals could be recognized and blown in the tunnel and recorded what kind of judgment each individual makes judgment. Then, when the left and right are the same size, 55% of the bees that could be measured slipped through the opening without bias toward the left and right, but bias was found in the selection of left and right individuals , One quarter of the 45% group had a strong leftward deflection, another one a strong rightward deflection. Speaking of simple probability, it is no wonder that the ratio of choosing left and right will be the same because it is an alternative state, but for individuals of 45% of the whole, "commitment" to either left or right It has been confirmed that there is.

By the way, it is also clear that when you change the size of the opening on the left and right, the tendency to choose the opening that is larger in proportion to the ratio of the difference in size becomes stronger.

What is particularly interesting in this result is that the individuals of "right handed" and "left handed" all accounted for 25% of the total. Mr. Srinivasan pointed out that, in addition to being interesting in the presence of things like "dominant hand" also in bees, unlike humans who have many "right-handed" people, left and right handedness are the same It points out that it is also noteworthy that it exists in proportion.

For small animals such as bees, making selections on either side of the left or right leads to a big difference in results in efficiently flying in the woods where trees grow. Especially Srinivasan points out that evenly distributed left and right leads to the result that the entire group can get out of the wood more quickly.

Furthermore, it is thought that this research result can be applied to Autonomous Flight Technology of Drone. Many engineers are paying attention to events that exist in nature such as animals around Mr. Srinivasan, and the findings found this time can be important hints for efficiently flying drones. Srinivasan said, "Biasing the program to autonomous flying drone to make some judgment to the right and some to judge to the left makes it more efficient for the entire group without complex control It will be possible to skip it in a similar way, "he says.
