Turn Robot around?

How can I turn this robot I’ve made around 180 deg. to face the other way? Everything I’ve tried his legs end up all wonky.

The constraints on this model are a little busted. At least, for what you want to do.

  1. Delete or mute the limit rotation constraints on the thigh and calf bones.

  2. Select the body and both foot control bones.

  3. Rotate in z axis, confirm.

Change the limit rotations to use local space on all leg bones.
