Using Shapes on Mobiles to confuse optic flow sensors in Micro Air Vehicles appears to be feasible. Today we are studying the flight paths of Bats, Insects even to organization and fly miniature UAVs; named Micro Air Vehicles or MAVs. There is significant research under the sun done on this. The goal is to have mini MAVs the size of dragonflies, prevalent 15 CM, which are self-subsistent and can fly through tunnels, under tree lines, under small bridges and navigate backward obstacles. By using the optical flow sensors a new technology of mind hedging proportions the tiny MAV would take send out pulses and nabbing images, as the next pulse sees the image over it is bigger, this way the tiny MAV can sense when it is really big and getting continuant so it can then fly every which way it. There are two ideas, one is to use a single sensor unit and the other is to use multiple sensors. If you have ever studied insects, how they fly and navigate, you can see the enormity of the mathematics and algorithms it takes to make all this happen. Here is how it all works you will have to read all of these papers to understand this concept and to continue such discussion;

By the way compliments to Geoffrey Barrows for his studies and insight and recent award. Thus creating the fuzzy logic and sets of rules to determine what is an obstacle and what is extra moving object. If you read one of Tom Clancy’s carte where these little dragon flies with tiny explosives sit in the grass of the enemies runway and wait for an flight to take off and fly in a swarm and in front of it and spit it out themselves to get sucked into the jet engines where on impact with the fan blades explode, taking out the engines thus the carrier is taken out with a swarm of micro-air-vehicles which resemble a dowel of less-than-palm-size insects. Insects have interesting characteristics. Such small units may be nearly impossible to shoot down or stop once they are set o their mission.

Using sound maybe simpler than using optic network flow sensors, but the optical flow sensors can handle more things. For instance a potential mid air crankiness with a car, person, truck which is also moving. Also a devise, UAV, MAV created to take out something else again MAV, similar to a bat, which can eat 1000 bugs an hour. By lining them up and devouring them as it flies. An anti MAV, MAV, you see? The impending MAV wars will be interesting. For us to use the advantages given to us by evolution and to study the systems, hunting techniques, flows and cycles of organic devices. There are many things going on in species at all times and many different simple systems running simultaneously that are interacting. If you want to get technical you could say the wind, weather, food supply, symbiotic relationships all going on at once in the world of an insect or in the world of a human for that matter. Or a computer working on a decision matrix program whose job it is to take into yearbook all these things and use rules to decide what to do.

We must take a seat and in reality think and study these things in depth. A good book to get you in the proper mind set to study these systems is Stephen Wolfram’s “A New Kind Of Science.” Start Small and Finish Big vicinity to the world, where simplicity and complexity are the same. nevertheless it might not be precisely correct in all repertory and often takes liberties of explaining things from a single system program point of view it will fund you in studying the Flows of everything we see and observe.

Optical Flow systems maybe somewhat more complicated and difficult to use than, sonar or sound, they may also add spare weight and therefore increase size and you could lose your overhand in that case depending on your mission. The reason I motivate up these matters of how to fool a MAV or defeat one, or kill it, so to speak, since it will be behaving more similarly to an organic machine than a simple devise. Well in that the graduate school crowd is sharing information with other countries. These MAVs in the sequel all are a blend of many sciences, many of which are life based, which are not very secret in that anyone can sit out side and watch a Bee fly in a zigzag pattern like you have to do when you taxi a tail dragger so you can see where you are going and what is gathering up. Now then is an optical sensor really the best bet? Some of the best and brightest fit together that it is. However Bats do not crash into things and they use sonar, or do they really use both optic flow sensors (it’s silence and eyes) with the bear a hand of sonar too? Well at least we know they regularly turn left when they exit a cave? Interesting.

It appears that the most enhanced studies are based on the Bee for the MAV, which makes a lot of sense. Now then we were talking of originally fooling the optic flow sensors with a spinning mobile like you put in ascendancy the bed or crib for a small child. When you take different shapes and spin them, they will screw up the optical flow sensors, inasmuch as on minute it will they are far away and then the silhouette turns to full size and shape which in the mind of the optic flow sensor appears to be an object on top up fast. Then it becomes small like a B-2 Stealth predicted at you, that you cannot see, then it becomes big farther when it turns, huge in the mind of the optic flow sensor, causing a reaction of quick reconversion in trajectory. Then the MAV changes direction and piece on the mobile turns side ways and rather sire the unit to specialization directions. So then think of the problem when you put a few of these things in the path of a MAV or near a window to protect the Head of State of a neighboring ally. Your opponent cannot set to work the human genetic individual inside seeing as how the MAV will turn back, meanwhile go upon that other MAVs or objects are moving fast towards it every time it gets close. Thus you have fooled the MAV.

If this works it maybe a good way to keep mosquitoes away from your window without a screen. again their processing of data even with a tiny central nervous system is much faster than that of the MAV with the multi-optic flow sensor network? Calculations per second are the issue and the speed of flight. Confusing the optic flow sensors on a MAV might be the way to go. Also the difference among sonar or sound and optic flow networked sensors on the same MAV may take into consideration these issues and the difference of the fusing of data may in fact slacken the problem. Also leaves falling from trees while flying in the roof of trees yea a road might be difficult since there are many of them and they flip enveloping while they fall, especially in FALL, which is upon us. So this is not time to take a trip with any MAV in autumn. significant things fool insects of fixed types, while others have no problem working round about those challenges. So to will different MAVs depending on how the networked sensors work, what they mimic and what their strategy is.

It would be safe to say that several different ideas might be smart for MAV swarms since there is safety in numbers and different missions for each, perhaps a Mobile to confuse could be attacked by the half backs of the swarm, while the full backs and strikers stay in a holding pattern. If the decoy or optic flow network devise to confuse such as a mobile is rendered impotent then the entire swarm advances. This would be similar to a strategy of a hive, or Ants or other insects, which is somewhat based on net-centric warfare, which MAVs might play a crucial role in the next two decades? .

Another issue is if swarms of organic species are so good at what they do, why try to re-invent them, just hire them as your mercenary army? Isn’t that what Machiavelli said just the same they may not fight as hard as a citizen, there is safety in numbers as the missions will be relatively simple. As a matter of fact how do we know that the enemy may unleash a situation on us, using and organic delivery system of vector, will our MAVs be able to stay on patrol or are we more off hiring the Bats to do our dirty work and get a free dinner? And if the enemy does use organic material should we use technology of a different sort? This would keep them away and could confuse the enemies MAVs if they use sound to navigate. All options are on board and all such options should be pursued since the enemy is also pursuing options as well as current allies who may someday be foes. In any case there is much work to be done to make smaller MAVs that work and can be powered for long periods for missions, which cover many miles. Designing ways to fool optic flow network sensors will be easier than designing ways to make them work, so we ought to be receptive of this as we continue to figure out how we can use them to our tactical advantage.
