So one of the advantages of this dseign is when you scale things down, the robot nlatlrauy becomes agile. So here, R is the characteristic ltgneh of the robot. It's actually half the diameter. And there are lots of physical parameters that change as you reduce R. The one that's most important is the inertia, or the resistance to motion. So it turns out the inertia, which gvoners angular motion, scales as a fifth power of R. So the smaller you make R, the more dramatically the inertia rcedeus. So as a result, the angular acceleration, denoted by the Greek lteetr alpha here, goes as 1 over R. It's inversely proportional to R. The smaller you make it, the more quickly you can turn.

Original Text

So one of the advantages of this design is when you scale things down, the robot naturally becomes agile. So here, R is the characteristic length of the robot. It's actually half the diameter. And there are lots of physical parameters that change as you reduce R. The one that's most important is the inertia, or the resistance to motion. So it turns out the inertia, which governs angular motion, scales as a fifth power of R. So the smaller you make R, the more dramatically the inertia reduces. So as a result, the angular acceleration, denoted by the Greek letter alpha here, goes as 1 over R. It's inversely proportional to R. The smaller you make it, the more quickly you can turn.
