This video shows a Nao robot attempt to do it's version of Tai Chi.
To see the Nao get up on its own go to www.youtube.com/watch?v=fYQrq4iCUqg or to see it complete the routine without falling over, go to https://www.youtube.com/watch?v=t4L5z4r7QS8
I've also added a video of how to use Choregraphe software to program the Nao robot to do this dance at https://youtu.be/0-G_7qq1ikc.
