Although in reality, this is a video where I had fun with video editing, it also has innovative content.
For example it is been a while that I wanted to test the two servomotors of the elbow that I built years ago, playing with the parts of a servomotor original.

The movement in addition to being smooth enough is also very useful, as the Robonova / Robozak it was almost totally lacking.

First of all, the purpose of the project was to integrate a pair of servo motors with additional function of the elbow on our friend Robonova / Robozak, or as I have renamed NovaXXL because of the many changes I've made.
Just to compare the two models:


ORIGINAL VERSION

Image



NovaXXL VERSION

Image

You may notice two major changes.
the addition hip joint, which perhaps will be the subject of a future analysis and the two elbows, which make the movement of the arm more versatile.


Image

the idea of ​​"reorganize" the servomotor has also come from the fact that if we take a simple servo motor and we add it to the arm, we would get such an effect, that to me, with all due respect to those who did it, but it is a do not really pretty (but it is my point of view):

Image

Another example:

Image

Having said this let's get to the system that I used.

It begins with the disassemble of a pair of servo that I did not use and I removed the logic and mechanics.


Image

Image

Image

After having taken the right size, it moves on to the "reduction" of the polygon entrusted to the valiant "blade" killer:

Image

Image

Image

And thus obtaining a servo motor "in miniskirt"

The gear housing will remain intact for obvious practical reasons:


Image

This mini block, will find place just above the servomotor forearm though rotated 90 °

Image

The bracket has been made ​​in the classic system of aluminum / hammering / fold:

tomorrow for the continuation.

Now is the time to clean the motor from pre-existing glue and prepare it for inclusion in a new housing.


Image


......... formed by a square tube, with a side equal to the diameter of the motor.

Image


Image


Image


.....remount the electronics .... and I turn the cables to an alternate location:


Image


Image


Image


.....another small reduction


Image


I go prolong contact between electronics and motor, in order to remove the circuitry from the motor itself.


Image


electronics will be inserted into its original slot.


Image


and .... staying in a slot formed by the bracket:


Image


Image


it's time to insert the motor with the new housing:


Image


Image


Image

a C bracket will be used to secure the two parts together:

Image


Image


Image


Image


End of the experiment.
