| Nov 19, 2016 at 16:11 | comment | added | supercat | A robo-cat wouldn't even need the hind legs to change its orientation. All it needs is the ability to have the hind section make a complete rotation relative to the front and then be in the same "state" as it was initially. After the hind section has made a complete rotation relative to the front, both sections will have a new orientation relative to the rest of the universe. | |

Very minor C -> H fix and bolding

I'm guessing "hinder-cat" (C) is supposed to be H ?

| Nov 29, 2013 at 10:53 | comment | added | Selene Routley | @David Thanks. Be sure to take a look at the link that QuantumMechanic just posted: shows another (and probably more realistic) way a cat rotates physics.stackexchange.com/q/24632/2451 | |
