"From the Ted Talk by Raffaello D'Andrea: Meet the dazzling flying machines of the future"

#### Unscramble the Blue Letters

If the monipsnoner is an exercise in frugality, this machine here, the omnicopter, with its eight propellers, is an exercise in excess. What can you do with all this surplus? The thing to notice is that it is highly symmetric. As a result, it is ambivalent to orientation. This gives it an eroaxnrrtdaiy capability. It can move anywhere it wants in spcae iicreprvetse of where it is facing and even of how it is rotating. It has its own complexities, mainly having to do with the interacting flows from its eight propellers. Some of this can be modeled, while the rest can be larneed on the fly. Let's take a look.

#### Open Cloze

If the ___________ is an exercise in frugality, this machine here, the omnicopter, with its eight propellers, is an exercise in excess. What can you do with all this surplus? The thing to notice is that it is highly symmetric. As a result, it is ambivalent to orientation. This gives it an _____________ capability. It can move anywhere it wants in _____ ____________ of where it is facing and even of how it is rotating. It has its own complexities, mainly having to do with the interacting flows from its eight propellers. Some of this can be modeled, while the rest can be _______ on the fly. Let's take a look.

#### Solution

1. extraordinary
2. learned
3. space
4. irrespective
5. monospinner

#### Original Text

If the monospinner is an exercise in frugality, this machine here, the omnicopter, with its eight propellers, is an exercise in excess. What can you do with all this surplus? The thing to notice is that it is highly symmetric. As a result, it is ambivalent to orientation. This gives it an extraordinary capability. It can move anywhere it wants in space irrespective of where it is facing and even of how it is rotating. It has its own complexities, mainly having to do with the interacting flows from its eight propellers. Some of this can be modeled, while the rest can be learned on the fly. Let's take a look.
