From the Ted Talk by Vijay Kumar: Robots that fly ... and cooperate
Unscramble the Blue Letters
So this is the kind of coordination we want our robots to have. So when we have a robot which is surrounded by neighbors — and let's look at robot I and robot J — what we want the robtos to do, is to monitor the sapoatiren between them, as they fly in foiotamrn. And then you want to make sure that this separation is within abptclacee levels. So again, the robots monitor this error and calculate the control commands 100 times a second, which then translates into motor commands, 600 times a second. So this also has to be done in a decentralized way. Again, if you have lots and lots of robots, it's impossible to coordinate all this information centrally fast enough in order for the robots to accomplish the task. Plus, the robots have to base their actions only on laocl ioomrifantn — what they sense from their neighbors. And then finally, we insist that the robots be agnostic to who their neighbors are. So this is what we call anonymity.

So this is the kind of coordination we want our robots to have. So when we have a robot which is surrounded by neighbors — and let's look at robot I and robot J — what we want the ______ to do, is to monitor the __________ between them, as they fly in _________. And then you want to make sure that this separation is within __________ levels. So again, the robots monitor this error and calculate the control commands 100 times a second, which then translates into motor commands, 600 times a second. So this also has to be done in a decentralized way. Again, if you have lots and lots of robots, it's impossible to coordinate all this information centrally fast enough in order for the robots to accomplish the task. Plus, the robots have to base their actions only on _____ ___________ — what they sense from their neighbors. And then finally, we insist that the robots be agnostic to who their neighbors are. So this is what we call anonymity.

So this is the kind of coordination we want our robots to have. So when we have a robot which is surrounded by neighbors — and let's look at robot I and robot J — what we want the robots to do, is to monitor the separation between them, as they fly in formation. And then you want to make sure that this separation is within acceptable levels. So again, the robots monitor this error and calculate the control commands 100 times a second, which then translates into motor commands, 600 times a second. So this also has to be done in a decentralized way. Again, if you have lots and lots of robots, it's impossible to coordinate all this information centrally fast enough in order for the robots to accomplish the task. Plus, the robots have to base their actions only on local information — what they sense from their neighbors. And then finally, we insist that the robots be agnostic to who their neighbors are. So this is what we call anonymity.
