Newbie question - Multiple tools on the z axis

Hi guys! im new here! im trying with this post to understand linux cnc possibilities. Im very new at this.

Is it possible to create robots (mainly with xyz axis) but with different tools on the Z plane? Could i have more than one tool at the Z axis at the same time? I know i have to learn a lot of HAL but not sure if is even possible.

Mainly, Im trying to create a compressed air robot graber for wood to move it around to different stations to be able to cut it, hole it, paint it, etc, etc, but im not sure if is possible with linux cnc or what kind of limitations i will find (besides my knowledge on hal lol).

Could you give me a few hints on this ? ty

(btw im sorry about my eng is not very good ty)

Im trying to understand if i could control a machine like this with linux cnc: (at 3:38 of the video). That's a robot arm but in my case i would try to build a cartesian robot that grabs planks the same way
