The Arms

I knew already this was going to be the trickest bit so did a few sketches first:

From this final rough sketch I ended up getting the first arm prototype done now I just have to reproduce a second one for the other arm and tweak.

Everything is working and moving as required. Only problem is the joint attaches the arm to the body isn't fixed so the arm droops (why I put the red block under the hand) but I'll fix that later.
