Next in line making arms.
Turn of palm I have done on the axis.
A twist shoulder and elbow I made on magnets. In each half is two magnets. For shoulder and elbow. Opposing magnets in one axis made on the principle - one fixed and the other is free, but is limited to move, so as not to be attracted to another magnet in this half.
In the central element set a fixed square magnet(so I wanted). Together with a fixed magnet in one of the halves they creates rotational axis. Free magnet in the second half himself centralized. Is no need to center all three magnets, but only two.
A bunch of glued parts ready for assembly of both arms.
The frame arms.
Arms is done.
A few photos of Junchoon already with arms.
