3D printing finally allowed lions to mount the gopro on a carbon fiber rod instead of aluminum angle rod.  It was much more stable & the energy burn was much less.  It only burned 280mAh/mile.    That may be a charging anomaly, but it would be a natural outcome of increased stability.  Helas, the farsteners started coming apart as the lion kingdom figured E6000 would bond to PLA.  E6000 does not bond to PLA.  CA glue seems to work best.

This would be a really shmick set of carbon fiber farsteners if it was on amazon.com. Lions never were impressed by 3D printed prototypes from startups, but carefully designed & manufactured parts can look really professional. 

The gopro mount is the mane item limiting progress on the next rover.  It's essential for it to eventually pan & track the lion.  How it's done determines what's in the next remote control.  A panning mount can now be 3D printed, but the tracking part is hard.

1 option is machine vision.  It entails a haar cascade for detecting all the faces & openface for ranking the faces.  Openface is over 5 years old.  It would require a $100 confuser just dedicated to the 1 task & wiring on the pole to capture video.  The confuser is rated at 10W or at least another 100mAh/mile.

The other option is finding the direction of the remote control RF signal.  A rotating parabolic antenna might do it.
