It looks like the hardware repository for the "open source" Handibot is seven months since the last commit (Sept 2015). No sign of V2.0 there. Is V2 somewhere else? or just not yet posted to [github.com] ?
I'm trying to get set up on our github repository so that I can upload everything I've created for the tool...in the meantime you can grab the model of handibot here: [www.dropbox.com]
