Hi,
Robotis Dynamixels are great motors and current model selections are good but not enough to carry batteries or walk itself without a support.
I am really curious about making it with Dynamixel MX-106 and MX-64 motors for legs and other critique parts. I know sizes and weights of the motors differ so the design must be replaced with stronger one.
Maybe “Poppy: the Hercule” model can be another progress

Yep it is possible and it is quite easy to do.
Actually, several parts are already designed to be compatible with MX-28 or MX-64. Not with MX-106 because of the price (500$), but it would be possible also.
For the moment, it is only on our private branches, but if you want them, it is possible push them in the public repository.
Here is an example with the pelvis part:
We manage the different compatibility options with Solidworks’ configurations.
