Broken legs - the work around

Even the weedier AX-12A Dynamixel servos used in the knee and hip joints have enough power to snap the weaker Bioloid frame parts - especially the F10 bracket.

The hexpod robot snapped two of these in early attempts at walking. I can blame my bad software, but it's not good when a software bug can cause a hardware failure...

So I've doubled up the F10 bracket, which should make it somewhere between 2 and 8 times stronger (the 8 times if the two layers are firmly clamped together and can't slide relative to each other). This seems to have done the trick. No more broken legs.
