I recently completed Z3US after about year of building and programming! Z3US is a humanoid robot built with the LEGO MINDSTORMS EV3 and NXT platforms. Z3US can move around via tank treads, controlled by a NXT joystick remote. Also, Z3US can mimic movements of the right arm via EV3 EXOSKEL3TON. Z3US uses a total of 2 NXT'S and 2 EV3'S (Including remotes).
One EV3 is used in the EXOSKEL3TON (Inspired by Daniele Benedettelli's [exoskeleton] and similar to Arthur Sacek's [Shadowing Humanoid] ). The second EV3 is in Z3US, and mimics the movements of the EXOSKEL3TON.
The NXT'S are used for mobilizing Z3US. One NXT is used for the joystick remote, and the second, for the actual motors that you control with the joystick remote. Both NXT'S use the programs from philohome.com .
I would like to thank those in the LEGO MINDSTORMS EV3 Group on facebook who helped me out. Also I would like to thank Bazmarc for all the help and support.
Following, are some photos and a video.
