Animating a robot arm

Hello developers :wave:

Im new on this platform so im sorry if this isn’t in the right catergorie.
Anyways I have a problem animating a robot arm, I can’t seem to find out how to give every single piece of arm a own track to animate while still being connected to each other.

(The arm im working with)

(Little more detail)

I want every single colour to move seperate from eatch other while still being attached.
Arm 1 = yellow
Arm 2 = red (I’m colorblind)
Arm 3 = puple
So when arm 1 moves i want arm 2 and 3 to rotate with it but while arm 1 is moving i want arm 2 and 3 to be animated at the same time (Like rotate or something). But as you can see i only have 1 animation track and i can add other tracks but if i do so they disapear instandly. So i have to move 3 arms with 1 track and thats simply impossible.

I tried following video’s, tutorials and forums but i geuss my brain isn’t understanding it…

Does anyone know a good tutorial on how to do this the right way or can explain me how to do this?

Thanks in advance!
