I've built my own GELLO setup (the setup the author based it's arm on) and it's quite neat, but as I only use it for teleoperation of an real arm, I wonder how useful this low cost arm really is? Considering limited range, probably backlash, and the limited torque Also it doesn't seems to use springs like GELLO which was a nice add, although the 3D printed parts where the spring was mounted broke quickly.
