What kind of servo?

Hey folks,

I have a little question for you people here;

I am doing a robot arm as a school project and as “design inspiration” I used this robot arm: youtube.com/watch?v=hfA_ThHh-_A
And I am curious if anyone of you know what kind of servo this guy is using for his gripper? It can be seen closer around 0:41 to 0:53.

And if not, it’s fine. Thought i’d just throw this out here and see if anyone of you recognize it.

Thanks in advance!

Maby a Hitec HS-5645MG ?

Look like a transparent blue servo.
Many HTX servo are like that… take a look

been doing some research… he had also posted some info on this project but no mention of the gripper servo.

Some of the small blue plastic servos that might be used in the gripper.
