First of all, I've been making allot of progress with Z3US. I've replaced the NXT used as a head with an EV3 and I've been programming the EV3's via Daisy Chaining :)
Second, I've started building a powered Exoskeleton! So far I've only been buying necessary parts and not actually started putting them together. My plan is to build just one exoskeleton arm and get it working then do the other arm.
The exoskeleton will only power the upper-body (arms). It'll be powered by electric linear actuators and the expected total power (including my own) is about 200 pounds of weight I will be able to lift.
I've already spent about $300 USD on parts! I'd better finish this one!
