I ran across a 3D Printable robot on Thingiverse that may be the next step beyond JD. Poppy The Robot
It looks really interesting. The main website for Poppy is
Unfortunately it uses Dynamixel Servos (which is not uncommon for academic projects) and they are really expensive. Also right now ARC has a problem with them. I haven't heard anything lately on when the fix might be coming.
Poppy appears to be a tethered robot but a wifi EZ-B v4 mounted in the head could certainly fix that. The other thing May be where to put the battery. Perhaps a battery backpack. I haven't heard when an EZ-B accelerometer might be on the way but I am sure that would be needed as well.
It would be fun to tinker with though. Just thought I would share the find.
