First - I needed to be able to move the drill-arm, but the old idea was to use an external servo and extensions. Not cool. So I decided to put the entire servo inside the Big Daddy. Guess what? It's a perfect fit!
|2) Partly assembled and looking good! There are smaller servos, but this one pulls approximately 5Kg, which|
is plenty of power to throw the arm around!
|3) The new joint very closely resembles the old joint, meaning the seam will be invisible.|
Once that was done, I needed to fix the servo "head" in the arm itself, otherwise it would just rotate around its own axis instead of moving the arm around...
|4) Part of the servo inserted and glued in place. The glue is just an extra precaution since |
I carved out a perfect hole before inserting the piece.
|5) Fully assembled (well, sort of) and ready to drill your balls out!|
Before assembling it for real, I need to replace the old multi-LED version of the helmet-light with a single LED that can show all colors. The reason for this is that the various colors shone with uneven brightness which the new one will hopefully remedy.
After that he's pretty much ready to roll - besides the angular motion from side to side, but that will be done using an external servo. I see no reason for Mr Bubbles to become fully mobile...
