The most difficult stages are now complete.
All 7 motors are installed together with the 2 control hubs. So the most complicated stages of the build are complete and everything can be controlled from my mobile phone.
A view from the front showing the various motor driven pistons that move the arm, jib, and bucket platform.
And from the rear. The next three stages should be just adding all the pretty stuff, like cowls, ladders, etc..
