Bio-Inspired Eye Stabilizes Robot's Flight
Transcript of Bio-Inspired Eye Stabilizes Robot's Flight
Biorobotics researchers have come up with the first aerial robot able to fly over uneven terrain that can be stabilized. In order to come up with its design the researchers looked at insects. Its optic flow sensors were inspired by insect’s vision. It can fly along something like a tunnel with uneven and moving walls without having to worry about measuring altitude or speed. It can fly by itself, and can easily avoid vertical obstacles. All of the other aircraft drones have an internal device known as an accelerometer. However BeeRotor doesn’t. It was made so that it can adjust its speed and still follow the terrain without the accelerometer. Meaning it moves much like a winged insect. It weighs 80 grams and is only 47 centimeters long. To measure the optic flow BeeRotor was equipped with 24 photodiodes located at the top and bottom of its eye. It can detect changes in the environment, and also its motion. BeeRotor has 3 feedback loops, which have 3 different reflexes on its optic flow. The first loop controls its altitude. The second controls its speed. The third stabilizes the eye. The reason they built BeeRotor was to see how it is that winged insects can fly without an accelerometer.
I think BeeRotor can be useful. Our world is full of mysteries so it can help reveal another mystery. The fact that it works just like an insect means that scientist are one-step closer to finding out just how exactly winged insects work. The insects have no accelerometer so how could they fly? BeeRotor can give them a step into the right direction as to how the insects fly.
Final Summary Statment
In conclusion BeeRotor is a very useful creation. It was made to help scientists come up with hypothesis as to how exactly winged insects fly with no accelerometer. Hopefully in the near future with the help of BeeRotor scientists can have their answer. Then the can work on uncovering the other mysteries of the Earth with the help of technology.

Accelerometer-/əkˌseləˈrämədər/noun- an instrument for measuring acceleration, typically that of an automobile, ship, aircraft, or spacecraft, or that involved in the vibration of a machine, building, or other structure.
Optic flow- the motion of all the surface elements from the visual world. As you move through the world, the objects and surfaces within the visual environment flow around you. The human visual system can determine your current direction of travel from the movement of these surfaces.
Photodiode- a semiconductor diode that, when exposed to light, generates a potential difference or changes its electrical resistance.
